Definition of Metric System

The metric system is a system of weights and measures that has been adopted by many countries of the world.

Australia started to adopt the metric system in 1970.

The standard metric units are:

  • length: the metre

  • time: the second

For example,

  • There are \(1,000\) millimetres in a metre.
  • There are \(1,000\) kilograms in a tonne.
  • There are \(10,000\) square metres in a hectare.
  • \(1\) centimetre is \(\dfrac{1}{100}\) metres.
  • \(1\) cubic centimetre is equal to \(1\) millilitre.
