Use of ternary numbers to balance an unknown integer weight from 1 to 40 kg with weights of 1, 3, 9 and 27 kg (4 ternary digits actually gives 34 = 81 possible combinations: −40 to +40, but only the positive values are useful)
Comparison of units of information: bit, trit, nat, ban. Quantity of information is the height of bars. Dark green level is the "nat" unit.

One trit is equivalent to log2 3 (about 1.58496) bits of information.

- Ternary numeral system

Base b = 3 : the unit is called "trit", and is equal to log2 3 (≈ 1.585) bits.
