Scale and maps
Lesson 4 of 9

Reading map scales

Objective. Convert between map distance and real distance.

The key idea

A scale of 1 : 50 000 means 1 cm on the map is 50 000 cm in reality, which is 500 m or 0.5 km.

Worked example

On a 1 : 25 000 map two towns are 6 cm apart. Real distance?

1 … 25
Illustrated card showing 1 … 25
  1. 16 × 25 000 = 150 000 cm.
  2. 2150 000 cm = 1500 m.
  3. 31500 m = 1.5 km.

Answer: 1.5 km

Practice

Each question comes with a picture and a listen button. Try it first, then reveal the answer.
