1 cm plan = 4 km réels
5 cm plan = 5 *4 = 20 km
50 km réels = 50 ; 4 = 12.5 cm plan
30 cm plan = 30 * 4 = 120 km
échelle = 1 / 400000

échelle 1 /2 000
1 cm plan = 2000 cm réels
1 cm plan = 20 m
10 cm = 10 * 2000 = 20 000 cm = 200 m
0.9 cm plan = 0.9 * 2 000 = 1 800 cm = 18 m
échelle 1 /500 000 = tu fais la même chose
1 cm plan = 500 000 cm réels = 5 km réels
