4. Prefixes (Table 1) Prefixes are short names and letter symbols for numbers (powers of ten). A prefix may be attached to the front of a unit to form a multiple of the unit. It does not form a sepa-rate unit. For example, the prefix kilo (k) means 1000, so kilometer (km) means 1000 meters. To preserve the sound of a prefix, stress the first ...
use of the SI. See NIST SP 330. Table 2. SI Prefixes. Prefixes produce units that are of an appropriate size for the application, e.g., millimeter for measurement of the dimensions of small screws, or kilometer for the measurement of distances on maps. Examples that show
teach you the metric prefixes that help describe all of these base units in quantities ranging from the insanely large to the incredibly small. Suggested Reading
The International System of Units (SI) is made up of 7 base units, featured on this chart with their Measurement League counterparts. The SI, commonly known as the metric system, is easy to use. KILOGRAM (kg) MASS. KELVIN (K) TEMPERATURE. The kilogram is the unit of mass, . The kelvin, unit of thermodynamic equal to the mass of the international.
SI units should be used with all physical quantities, where appropriate. Prefixes should be used where appropriate. include pico (p), nano (n), micro (μ), milli (m), kilo (k), mega (M), giga (G) and tera (T). Appropriate use of scientific notation.
SI prefixes See also prefixes for binary multiples adopted by the IEC. The 20 SI prefixes used to form decimal multiples and submultiples of SI units are given in Table 5.
