What are prefixes in physics?

A unit prefix is a specifier or mnemonic that is prepended to units of measurement to indicate multiples or fractions of the units. Units of various sizes are commonly formed by the use of such prefixes. The prefixes of the metric system, such as kilo and milli, represent multiplication by powers of ten.

What are the 7 metric prefixes?

  • In the SI, designations of multiples and subdivision of any unit may be arrived at by combining with the name of the unit the prefixes deka, hecto, and kilo meaning, respectively, 10, 100, and 1000, and deci, centi, and milli, meaning, respectively, one-tenth, one-hundredth, and one-thousandth.

Why do we use SI prefixes?

SI prefixes are used to form decimal multiples and submultiples of SI units. They should be used to ensure numerical values presented remain on the ‘human scale’ – ideally between 1 and 100. The grouping formed by a prefix symbol attached to a unit symbol constitutes a new inseparable unit symbol.
