1. There is only one unit of measurement for each physical quantity.

2. You can use multiplying prefixes to express the size of a measurement by using a multiplying prefix. For example, 1 000 m = 1 km; 0.001 m = 1 mm.

3. It is a decimal system. Fractions are expressed as decimals. This allows unit conversions without doing math — simply by shifting the decimal point.
