Lesson details
Key learning points
- Ratios are often used to describe converting between metric and imperial measurements.
- The ratio is either in the simplest form or in unitary form.
- 5 miles is roughly 8 kilometers, the approximation is to allow for easy mental calculations.
Keywords
Metric unit - Metric units are based around the standard units of metre, gram and litre.
Centi- - Centi placed before a unit means 1/100
Milli- - Milli placed before a unit means 1/1000
Kilo - Kilo placed before a unit means 1000 times.
Imperial unit - Imperial is a system of units for measuring, which was created in the early 1800s during the British Empire.
Common misconception
800 cm is further than 80 m because 800 is a larger number than 80.
Each unit of distance (e.g. cm, metre, km) describes a different-sized distance. 1 cm is 1/100 the size of a metre, meaning that 800 cm = 8 m is a shorter distance than 80 m.
