Important to know
Convert length between metric units, inches, feet, yards and international miles.
Feet and miles use international definitions, not the former US survey foot. This changes length units only and does not calculate area or distance traveled.
Formula and methodology
Convert to metres, then divide by the target factor. 1 in = 0.0254 m; 1 ft = 0.3048 m; 1 yd = 0.9144 m; 1 mi = 1,609.344 m.
Example
1 mile equals 1.609344 kilometres.
