The symbols for derived units are obtained by means of the mathematical signs for multiplication, division, and use of exponents. For example, the SI unit for velocity is the meter per second (m/s or m • s-1), and that for angular velocity is the radian per second (rad/s or rad • s-1). Some derived SI units have special names and symbols.
The conversion between different SI units for one and the same physical quantity is always through a power of ten. This is why the SI (and metric systems more generally) are called decimal systems of measurement units. [10] The grouping formed by a prefix symbol attached to a unit symbol (e.g. ' km ', ' cm ') constitutes a new inseparable unit ...
6 sty 2023 · This table gives easily remembered, approximate conversion factors for some common units, as well as more precise factors. Boldfaced values are exact. But remember, estimated values don’t warrant precise conversions.
Metric Conversion > Metric System • Metric Prefixes. Table of metric system prefixes, symbols, and multiplication factors. The metric system defines prefixes and corresponding symbols for positive and negative powers of 10, as applied to each unit of measure.
A metric prefix is a unit prefix that precedes a basic unit of measure to indicate a multiple or submultiple of the unit. All metric prefixes used today are decadic. Each prefix has a unique symbol that is prepended to any unit symbol.
