What is a centimeter?
A centimeter (cm) is one hundredth of a meter and just under four tenths of an inch (0.3937 inches). The prefix comes from the Latin centum, a hundred.
Divide centimeters by 30.48 to get feet, or multiply feet by 30.48 to get centimeters. The factor is exact, as a foot is 30.48cm, and a single centimeter is about 0.0328 feet.
The centimeter was the base unit of length in the CGS (centimeter, gram, second) system that physicists used before SI, which is why older physics talks about dynes and ergs.
What is a League?
A league was originally roughly the distance a person could walk in an hour, about 3 miles (4.8 kilometers). The exact length varied with the country and the period.
A league is an old unit of length, usually around 3 miles or 5 kilometers, though the exact figure varied by country and period. Jules Verne's Twenty Thousand Leagues Under the Sea is about distance travelled, not depth – 20,000 of his 4 kilometer leagues is 80,000 kilometers, twice around the Earth.
