Distances on maps

  • To work out distances from a map, measure the scale given to find out the relationship (e.g. 1cm = 100m).
    • Then measure the distance on the map and use the relationship to convert this to the distance in real life.

Scale factors as ratios

  • Map scales can be written as a ratio such as 1 : 5000.
  • This means that each unit on the map represents 5000 units in real life.
    • 1cm on the map = 5000cm in real life.
