Metric and imperial
The metric system scales by 10 (1 m = 100 cm = 1,000 mm; 1 km = 1,000 m). The imperial system uses 12 inches per foot, 3 feet per yard and 1,760 yards per mile. The bridge between them: 1 inch = 2.54 cm exactly.
How to use it
Choose a unit to convert from, a unit to convert to, and enter the value. The result shows above, and the table lists the value in every unit at once — handy for a quick cross-check.
