Scaled Units
- There are 20 SI prefixes used to form multiples and submultiples of SI units.
- Consider the earlier example of the height of the Washington Monument. We may write hW = 169 000 mm = 16 900 cm = 169 m = 0,169 km using the millimetre (SI prefix milli, symbol m), centimetre (SI prefix centi, symbol c), or kilometre (SI prefix kilo, symbol k).
- When these are used in the EDCS, we refer to them as scaled units.
- Example:
- Unit = Metre
- Scale = Kilo
