Imperial units are defined exactly in metric terms by the 1959 international yard and pound agreement, so conversions are exact.
1 in = 2.54 cm
1 ft = 12 in = 0.3048 m
1 yd = 3 ft = 0.9144 m
1 mi = 5,280 ft = 1.609344 km
1 nautical mile = 1,852 m
Examples
- 12 in × 2.54 = 30.48 cm.
- 10 km ÷ 1.609344 ≈ 6.2137 mi.
- 6 ft = 1.8288 m.
