The relationship between distance on the ground and distance on the

**map**is known as the**scale**of the**map**. Typically,**scale**is expressed as a ratio such as**1**:**50,000**or**1**:10,000. If we take**1**:**50,000**, this**means**that**1**centimetre on the**map**equals**50,000**centimetres (or 500 metres) on the ground.Keeping this in consideration, how do you find the scale?

To find a

**scale**factor between two similar figures, find two corresponding sides and write the ratio of the two sides. If you begin with the smaller figure, your**scale**factor will be less than one. If you begin with the larger figure, your**scale**factor will be greater than one.How do you figure out the scale of a map?

**Here are four simple steps you'll want to follow:**

- Find a map of an area you want to use.
- Find both the actual and measured distances of two points on your map.
- Divide the actual distance by the measured distance on the map for your scale.
- Place your scale numbers on the map.
