## Measurement and Units of Measurement

### Measurement of Distances

There are two types of distance that can be measured on the map.

#### Measurement of Straight Line Distances

This is the measurement of distance between two places on a straight line. A straight line distance is usually referred to as “as the crow flies” i.e. on a straight route or way.

Straight Line

##### Procedure of Measuring Straight Line Distances
1. Locate the two places or points involved in question on the map.
2. Measure the distance between the two places with a ruler
3. Relate the distance measured in centimeter on the map to the scale of the map.

Example:

Calculate the distance as the crow flies from point A to point B.
