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, <u>human height is a quantity that can be perfectly measured in meters.</u> For instance:
- Stephen Curry: 1.91 meters
- Lebron James: 2.03 meters
