Length Units Conversions

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

The most common definition of length is that it is the measurement of the extent of something along its greatest dimension.

	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 4	10⁵	1 000	1
