Each square on the map is 2 cm by 2 cm (4 cm 2) and represents 1 km 2 on the surface of the Earth. For 1:25,000 maps, the grid lines are 4 cm apart. Each square on the map is 4 cm by 4 cm (16 cm 2) and represents 1 km 2 on the surface of the Earth. In each case, the grid lines enclose one square kilometre.
The centimetre (SI symbol: cm) is a unit of length in the metric system equal to 10 −2 metres ( 1 / 100 m = 0.01 m). To help compare different orders of magnitude, this section lists lengths between 10 −2 m and 10 −1 m (1 cm and 1 dm). 1 cm – 10 millimeters; 1 cm – 0.39 inches; 1 cm – edge of a square of area 1 cm 2
