When I was teaching myself the base-12 times tables I wasn't aware of any existing conventions so I had to make up my own numbers:

Once lev is lev.
Two levs are tentweel.
Three levs are twotwy-nine.
...
Lev levs are tentwy-one.
Twelve levs are levtwy.
Onetweel levs are levtwy-lev.
Twotweel levs are one gross and ten!

I am fun at parties, let me tell you.

Well the problem with duodecimal is you're using a base-10 counting system to label your base-12 counting system.

Never heard the base 12 system being referred to as dozenal. Duodecimal, yes, but never dozenal.

So thanks to the French to keep me from being confused when counting and doing math... then again if we were raised using it, a video on base 10 may have been just as confusing.

radxsays...

That is certainly true. Our word for "dozen" went through a slighty different evolution and is now somewhat unfit to be the base of a term for... bases. Instead, we use a simplified terminology: system of eights, system of tens, system of twelves, system of sixteens, etc.
