Metric and imperial length
The metric system builds every length unit from the meter: 1 km is 1,000 m, 1 cm is one hundredth of a meter. Imperial units relate to each other in twelves and thousands instead — 12 inches to a foot, 3 feet to a yard, 1,760 yards to a mile. The bridge between the two systems is exact: 1 inch is defined as precisely 2.54 cm.
