Definition of a mile

A mile (mi) is a unit of length in both the customary and imperial systems of measurement in the United States. The international mile, abbreviated “mile,” is defined as follows:

1 mile equals 5,280 feet (1,760 yards).

1 mile equals 1609.344 metres or

1 mile equals 1.609344 kilometres

The mile is generally used in the United States, the United Kingdom, and their territories. Most other nations use kilometres instead of miles in contexts when these countries would use miles. Speed, for example, is often represented in miles per hour (mph) rather than kilometres per hour (kph) elsewhere. In addition, distances in athletic events such as marathons or cycle races are often measured in miles rather than kilometres (km).

How to convert miles to kilometres?

Solved examples

Example 1: Use the miles to km algorithm and convert 15 miles into km.

Solution: 

By the miles to km algorithm formula,

Miles to km = 15 × 1.609344

= 24.14016 km

Therefore, 15 miles is equal to 24.14016 km.

Example 2: The distance between Peter’s college to his house is 4 miles, how many kilometres does Peter cover from his college to home?

Solution: 

To find: Distance travelled in kilometres.

Distance between college to house  = 4 miles (given)

Using miles to km formula,

Distance travels in kilometres by Peter  = (4 miles x 1.6)

= 6.4 (approx)

Answer: Peter travels approximately 6.4 kilometres from his college to home.

Example 3: George travels 10 miles on his bike every morning. Determine George’s distance travelled in kilometres using the miles to km method.

Solution: 

To find: how much George travels in km

Distance travelled by George every morning = 10 miles.

Distance travelled by George in km = (10 miles x 1.6) (approx)

= 16 km (approx)

Answer: The distance travelled by George on his bike is 16 km.
