Converting map scale to ground distance and/or map distance and vice versa. If you have a map scale, the calculator returns ground distance values per cm and inch. If you have a map scale and a map distance, the calculator returns the distance on the ground. If you have a map distance and a ground distance, the calculator returns the map scale. If you have a map scale and a ground distance, the calculator returns the map distance.

1 cm = 0.394 in = 0.033 ft = 0.01 m
2.54 cm = 1 in = 0.083 ft = 0.025 m
30.48 cm = 12 in = 1 ft = 0.305 m
100 cm = 39.370 in = 3.289 ft = 1 m = 0.001 km
3,280.84 ft = 1,000 m = 1 km = 0.621 mi = 0.540 nm
5,280 ft = 1,609.34 m = 1.609 km = 1 mi = 0.869 nm
72,000 in = 6,000 ft = 1.852 m = 0.002 km = 1.151 mi = 1 nm
