How do you read a map for D of E
The maps you use for DofE are 1:25,000 scale
On 1:25,000 maps 4cm = 1km (100,000cm). The 1:25,000 scale means that any distance unit on the map (for example the width of your finger)= 25,000 times that distance on the actual ground. So 1cm on the map would become 250 metres in the real world i.e. 1cm = 25,000cm.
