kelvin (K)

The International Standard unit of temperature. Absolute zero equals 0°K = -273.16°C = 459.69°F. A temperature increase of 1°K is numerically equal to an increase of 1°C.

kilo (k)

Prefix, used in the International System of Units, denoting multiplication by 1000.

See prefix.

Kelvin

A unit of measurement of temperature. Part of the SI system of measurement, the Kelvin (K) scale starts at absolute zero (-273.15). Each Kelvin degree is the same as a Celsius degree. As a result, 0ºC (freezing water) is equal to 273.15K, and 100ºC (boiling water) is equal to 373.15K. From British physicist and mathematician Lord William Thomas Kelvin (1824-1907). See color temperature and SI units.

kilo

Thousand (10 to the 3rd power). Abbreviated "K." For technical specifications, it refers to the precise value 1,024 since computer specifications are based on binary numbers. For example, 64K means 65,536 bytes when referring to memory or storage (64x1024), but a 64K salary means $64,000. The IEEE uses "K" for 1,024, and "k" for 1,000. See KB, binary values and space/time.
