About this tool
Since the 1959 international yard and pound agreement, imperial lengths have been defined exactly in metric: 1 inch = 2.54 cm, 1 foot = 0.3048 m, 1 yard = 0.9144 m and 1 mile = 1,609.344 m. Conversions here use those exact factors, so results are precise, not rounded approximations. The nautical mile (1,852 m) is used at sea and in aviation.
