How to Do Ternary or Trinary, Base 3 Numbering System Conversions Lesson / Tutorial Examples

Latest update: November 24, 2024

If you understand the everyday decimal (base 10) number system, then you already understand the ternary, base 3 counting and numbering system. You just don’t know you know yet. The complete lesson immediately follows the short semantics note about "ternary" versus "trinary".

Base 3 Conversion - Base 3 to Base 10 and Back - 0 1 2

How to Learn the Ternary Base 3 Numbering System

A complete lesson and examples.

Semantics Note

Ternary is the primary descriptor used to identify base 3 (using the digits 0 1 2) in mathematics as relates to numbering systems. Trinary is the primary descriptor used to identify base three as relates to logic (using the digits -1 0 +1); but the term has also been used in place of ternary. This page does not address the logic definition of trinary. This page is about and explains the base 3 number system; usually called ternary, but sometimes referred to as trinary.

A Quick Review of Base 10 Structure...


Base 10 Decimal Orders of Magnitude

1 · 10 · 100 · 1,000 · 10,000 · 100,000

Positional

100,000 · 10,000 · 1,000 · 100 · 10 · 1

We use the base 10 numbering/counting system in our day-to-day living. Base 10 has ten numbers (0-9) and orders of magnitude that are times ten.
  • The lowest order number represents itself times one.
  • The next order number represents itself times 10.
  • The next order number represents itself times 10 x 10, or itself times 100.
  • The next order of magnitude would be 10 x 10 x 10, or 1000.
And so on. A base 10 example would be the number 3528. This number means that there are:
  • Eight 1’s,
  • two 10’s,
  • five 100’s,
  • and three 1000's.
Which represents 8 + 20 + 500 + 3000 for a total of 3528.

The Ternary or Base 3 Numbering System...

...uses the same structure, the only difference being the orders of magnitude. Base 3 or ternary has three numbers: 0, 1, and 2.

The orders of magnitude are times three.
  • The lowest order number represents itself times one.
  • The next order number represents itself times 3.
  • The next order number represents itself times 3 x 3, or itself times 9.
  • The next order of magnitude would be 3 x 3 x 3, or itself times 27.
  • The next order of magnitude would be 3 x 3 x 3 x 3, or itself times 81.
And so on.

Orders of Magnitude in Base 3

  • 1 · 3 · 9 · 27 · 81 · 243 · 729 · 2,187 · 6,561

Positional

  • 6,561 · 2,187 · 729 · 243 · 81 · 27 · · 3 · 1

A basic, first example of a ternary number would be the base 3 number 11111. This would mean there are:
  • one 1,
  • one 3,
  • one 9,
  • one 27,
  • and one 81.
Which represents 1 + 3 + 9 + 27 + 81 for a total of 121 in Base 10 decimal.

Another base 3 example would be the number 1120. This number means that there are:
  • No 1’s,
  • two 3’s,
  • one 9,
  • and one 27.
Which represents 0 + 6 + 9 + 27 for a total of 42 in base 10 decimal.

Another base 3 example would be the number 2101. This number means there are:
  • One 1,
  • No 3's,
  • One 9,
  • And two 27’s.
Which represents 1 + 0 + 9 + 54 for a total of 64 in base 10 decimal.

How to Do Duodecimal, Dozenal, Base 12 Number System Conversions — Examples, Math Problems

Latest update: November 24, 2024

If you understand the everyday decimal (base 10) number system, then you already understand the duodecimal, base 12, dozenal counting and numbering system. You just don’t know you know yet. The complete lesson immediately follows the short introduction.

For other base numbering systems, check out mathschool.etsy.com.


Timekeeping is heavily reliant on the number 12 and its composites (evenly divisible numbers: 2, 3, 4, 6).


How to Learn the Duodecimal, Dozenal, Base 12 Numbering System


An Interesting "Political" Side Note.

The base 12 numerical system, also known as the duodecimal or dozenal system, is just like all the other base numbering and counting systems. However, this is the only base numbering system which has a "political" aspect to it. This has to do with the number 12 being a very useful number and as to which symbols to use for the base 10 numbers "10" and "11".

If one wishes to remain within the standardized structure of hexadecimal and the other base numbering and counting systems up to and including base 36, then the use of sequential numbers and letters should be used. Thus, as in hexadecimal, the base 10 number "10" is equal to the base 12 number "A", and the base 10 number "11" is equal to the base 12 number "B".

Others advocate the use of different symbols, some examples being:
  • 10 = T
  • 10 = X
  • 11 = E
This how-to tutorial will stick with the base 2 through base 36 mathematical "standard" of 10 being designated by "A" and 11 being designated by "B".

Complete Lesson and Examples

A quick review of the decimal, base 10 structure...

Base 10, Decimal Orders of Magnitude
1 · 10 · 100 · 1,000 · 10,000 · 100,000
Positional
100,000 · 10,000 · 1,000 · 100 · 10 · 1

We use the base 10 numbering/counting system in our day-to-day living. Base 10 has ten numbers (0-9) and orders of magnitude that are times ten.
  • The lowest order number represents itself times one.
  • The next order number represents itself times 10.
  • The next order number represents itself times 10 x 10, or itself times 100.
  • The next order of magnitude would be 10 x 10 x 10, or 1000.
And so on.

A base 10, decimal example would be the number 7824. This number means there are:
  • Four 1’s,
  • Two 10’s,
  • Eight 100’s,
  • And seven 1000's.
Which represents 4 + 20 + 800 + 7000 for a total of 7824.

The duodecimal, base 12, dozenal numbering system...

...uses the same structure, the only difference being the orders of magnitude. Base 12 aka duodecimal has twelve numbers (0 thru B). The numbers are:
  • 0 = 0, 1 = 1, 2 = 2, 3 = 3, 4 = 4, 5 = 5, 6 = 6, 7 = 7, 8 = 8, 9 = 9
  • A = 10
  • B = 11
The orders of magnitude are times twelve.
  • The lowest order number represents itself times one.
  • The next order number represents itself times 12. The next order number represents itself times 12 x 12, or itself times 144.
  • The next order number represents itself times 12 x 12 x 12, or itself times 1728.
  • The next order number represents itself times 12 x 12 x 12 x 12, or itself times 20736.
And so on.

Positional

248832 · 20736 · 1728 · 144 · 12 · 1

A basic, first example of a duodecimal number would be the base 12 number 11111. This would mean there is:
  • one 1,
  • one 12,
  • one 144,
  • one 1728,
  • and one 20736.
Which represents 1 + 12 + 144 + 1728 + 20736 for a total of 22621 in base 10 decimal.

Another base 12 example would be the number 2B9A. This number means there are:
  • Ten 1’s,
  • Nine 12’s,
  • Eleven 144’s,
  • And two 1728’s.
Which represents 10+108+1584+3456 for a total of 5158 in base 10 decimal.

Another base 12 example would be the number A51B. This number means there are:
  • Eleven 1’s,
  • One 12,
  • Five 144’s,
  • And ten 1728’s.
Which represents 11+12+720+17280 for a total of 18023 in base 10 decimal.

Some of the Comments from the Previous Hosting Platforms

  • Commenter, Will Apse, said: I'm a bit weird about the number 12. As a kid I used pounds, shillings, and pence for money with 12 pennies in the shilling and twenty shillings in the pound (decimalized when I was 12, lol). This might be why I often think about the oddities of 12's. Money and time are rather important.
  • Commenter, DreamerMeg, said: I was brought up in the UK pre decimal money, same as Will Apse, but it's still difficult for me to get my head round the idea of base 12.
  • Commenter, BradMastersOCcal, said: Binary to base 12 is not as clean as base 8 (3 bits) or 16 (4 bits); this allows binary to just overflow into the next number. Base 12 has to use 4 bits but stop at 1011 (B). It is more like BCD. I had no idea this was a popular common base. Thanks, it is a very interesting article.
  • Commenter, DreamerMeg , said: As a child, we had to learn to count in 12's for the UK's monetary system. Counting in 10's is a lot easier. We had a class of 7-year-olds chanting 12 pence is 1 shilling, 18 pence is 1 and sixpence, 24 pence are two shillings, 30 pence is 2 and sixpence, 36 pence is three shillings! The UK went decimal in 1971 but I can still calculate between new money and old money and between decimal measurement systems (SI units) and the old pounds and ounces. Keeps the brain active, but I don't know that it's useful. Good article.

Numbering System to Decimal Base 10 Lessons

HAL says hi.

Introduction and Start of Base Number Systems Tutorials

These four base numbering system lessons use the exact same teaching methodology. As such, when you have learned one, you will have learned them all. There is also some repetitiveness, purpose being to reduce unnecessary scrolling. Comparisons of different base number systems can also prove useful.

If one understands the everyday, base 10 decimal number system; then you already understand the base 2, base 4, base 8, and base 16 numbering systems. You just don’t know that you know yet.

As you know, we use the decimal, base 10 numbering system in our day-to-day lives. The decimal base 10 system has ten numbers (0-9) and orders of magnitude that are times ten. The lowest-order number represents itself times one. The next-order number represents itself times ten. The next order number represents itself times 10 x 10 or itself times 100. The next order number represents itself times 10 x 10 x 10 or itself times 1000. And so on.

An example of the decimal base 10 system would be the number 7824. This number means there are:
  • Four 1’s,
  • two 10’s,
  • eight 100’s,
  • and seven 1000's.
Which represents 4 + 20 + 800 + 7000; for a total of 7824.

Tutorial continues below for the base numbering system lesson of your choice. This is a large file, your selection may take a few seconds to display the correct section.

Base 4, also known as the quaternary number system, is predominantly used in DNA genotyping and some electronics applications, etc. [A year 2019 update. Scientists have added four more letters to the DNA alphabet, so base 8 may also be relevant.]

This lesson gives you everything you need to know for converting from quaternary aka base 4 to decimal and for converting from decimal aka base 10 to quaternary. If you understand the decimal number system (or the binary base 2 numbering system for that matter), then you already understand the quaternary (base 4) number system.

Per the introduction, base 10 has ten numbers (0-9) and orders of magnitude that are times ten. The orders of magnitude are l, 10, 100 (10x10) , 1000 (10x10x10), etc.

An example would be the number 7112. This number means that there are:
  • two 1’s,
  • one 10’s,
  • one 100’s
  • and seven 1000’s.
Which represents 2 + 100 + 100 + 7000; for a total of 7112.

How to Do the Quaternary Base 4 Numbering System


Base 4 uses the same base 10 structure, the only difference being the orders of magnitude. Base 4 has four numbers (0-3) and orders of magnitude that are times four . The lowest-order number represents itself times one. The next-order number represents itself times four. The next order number represents itself times 4x4 or itself times 16. The next order number represents itself times 4x4x4 or itself times 64. The next order number represents itself times 4x4x4x4 or itself times 256. And so on.

Orders of Magnitude in Base 4

Positional

16384 · 4096 · 1024 · 256 · 64 · 16 · 4 · 1

A basic, first example of a quaternary number would be the base 4 number 11111. This would mean there is:
  • one 1,
  • one 4,
  • one 16,
  • one 64,
  • and one 256.
Which represents 1 + 4 + 16 + 64 + 256; for a total of 341 in Base 10 decimal.

Another base 4 example would be the quaternary number 321. This number means that there are:
  • one 1’s,
  • two 4’s,
  • and three 16’s.
Which represents 1 + 8 + 48; for a total of 57 in decimal.

Another base 4 example would be the quaternary number 3023. This number means that there are:
  • three 1’s,
  • two 4’s,
  • no 16’s,
  • and three 64’s.
Which represents 3 + 8 + 0 + 192; for a total of 203 in decimal.

If you understand the decimal (base 10) number system we use in our everyday lives, then you already understand the quinary (base 5) number system. You just don’t know that you know yet.

We use the decimal (base 10) number system in our day-to-day living. Base 10 has ten numbers (0-9) and orders of magnitude are times 10. The lowest-order number represents itself times one. The next-order number represents itself times 10. The next order number represents itself times 10x10 or itself times 100. The next order number represents itself times 10x10x10 or itself times 1000. And so on.

A decimal base 10 example would be the number 2417. This number means there are:
  • seven 1’s,
  • one 10,
  • four 100’s,
  • and two 1000’s.
Which represents 7 + 10 + 400 + 2000; for a total of 2417.

The Quinary, Base 5 Numbering System Uses the Same Structure...

...the only difference being the order of magnitude. Base 5 has five numbers (0 1 2 3 4) and orders of magnitude are times five. The lowest-order number represents itself times one. The next-order number represents itself times 5. The next order number represents itself times 5x5 or itself times 25. The next order of magnitude would be 5x5x5 or 125. And so on.

A base 5 to decimal base 10 example would be the number 3142. This number means there are...
  • two 1’s,
  • four 5’s,
  • one 25,
  • and three 125's.
Which represents 2 + 20 + 25 + 375 for a total of 422 in base 10.

Another base 5 to decimal base 10 example would be the number 2011. This number means there are...
  • One 1,
  • one 5,
  • no 25's,
  • and two 125's.
Which represents 1 + 5 + 0 + 250; for a total of 256 in base 10.
