There are many measurement systems, and the ones by Système international and the imperial system are arguably two of the most famous. There are also the furlong-firkin-fortnight (FFF) system and the CCC system by Jan Misali, both of which are sarcastic systems made as a joke. I have here a system that falls into the latter category that aims to be as difficult to use as possible. Here are the base units:
|standard gravity |
|vacuum permittivity |
|specific heat of water at 25°C |
Let’s try to derive the units for some common dimensions.
We know volume is represented by , so is our unit of length.
We can’t use nor , since those have and , respectively, that needs to be removed by multiplying its own reciprocal, which cancels itself out. That leaves us with and to be manipulated. Time can be represented by seconds, so we have
We can replace with and with to get
Velocity is acceleration times time, so
We can replace and with and , respectively, to get
Force is mass times acceleration, so
Momentum is mass times velocity, so
Energy has the same units as work, which is force times distance, so
We can replace in , momentum, velocity, and length accordingly:
Electric Field is force per charge, so
Voltage is energy per charge, so
Capacitance is charge per voltage, so
Current is charge per time, so
Resistance has the same units as vacuum permittivity divided by velocity, so
We can replace in and velocity accordingly:
What about luminous intensity and substance amount?
I don’t know how luminous intensity works so I can’t list an overcomplicated version of it. But feel free to use candela.
For substance amount, I don’t know any established units that are in the range of Avogadro’s Number that are ridicuous, so I’ll just say the Baker’s Dozen works.
