When do you need 里 → km?
Height in feet, home measuring, running distances and overseas furniture sizes are the top use cases for centimeter-foot lookups. When mixing imperial and metric, convert to meters first. For example: 180 cm is 5 ft 11 in on a US form; a 32-inch suitcase is about 81 cm diagonally, and cabin bags must stay under 20 in (about 51 cm).
Where do 里 and km come from?
Metric is anchored to the meter (defined via the speed of light since 1983); imperial is anchored to the foot, with 12 inches per foot and 1,760 yards per mile. The 1959 international agreement fixed 1 yd = 0.9144 m — the bridge between both systems.
