Length Units Conversions

The most common definition of length is that it is the measurement of the extent of something along its greatest dimension. That, of course, is for physical entities. Length is also used to describe passing of time, but that is not covered here (unless you are measuring the length of a timeline chart).











Standard units = Meter (m) for metric, foot (ft) for English

  inch foot mile centimeter meter kilometer
1 in = 1 8.333 * 10-2 1.578 * 10-5 2.540 2.540 * 10-2 2.540 * 10-5
1 ft = 12 1 1.894 * 10-4 30.48 0.304 8 3.048 * 10-4
1 mi = 6.336 * 104 5 280 1 1.609 * 105 160 9 1.609
1 cm = 0.393 7 3.281 * 10-2 6.214 * 10-6 1 10-2 10-5
1 m = 39.37 3.281 6.214 * 10-4 100 1 10-3
1 km = 3.93 7 * 104 3 281 0.621 * 104 105 1 000 1
