The SI, or International System of Units, comprises seven base units of measurement: ampere, kelvin, second, metre, kilogram, candela, mole, plus 20 prefixes that can be applied to each of them in order to create multiples and fractions.
The meter is the basic unit of lenght measurement. For example, human height is a quantity that can be perfectly measured in meters. For instance:
- Stephen Curry: 1.91 meters
- Lebron James: 2.03 meters
