Kelvin, First Baron. Title of William Thomson 1824-1907. British mathematician and physicist known especially for his work on heat and electricity. In 1848 he proposed a scale of temperature independent of any physical substance, which became known as the Kelvin scale.kelvin(K) A scale of temperature measurement in which each degree is equal to 1⁄273.16 of the interval between 0 K (absolute zero) and the triple point of water. K = °C + 273.16.

kelvin, abbr. K, official name in the International System of UnitsInternational System of Units,
officially called the Système International d'Unités, or SI, system of units adopted by the 11th General Conference on Weights and Measures (1960). It is based on the metric system.

a temperature scale having an absolute zero below which temperatures do not exist. Absolute zero, or 0°K;, is the temperature at which molecular energy is a minimum, and it corresponds to a temperature of −273.

A temperature in kelvin may be converted to one in degrees Celsius (°C) by the subtraction of 273.15.KelvinStandard unit for color temperature, abbreviated K. A Kelvin unit is the basis of all temperature measurement, starting with 0 K at absolute zero.Kelvin the unit of thermodynamic temperature, equal to 1/273.16 of the thermodynamic temperature of the triple point of water; designation K. It was named after W. Thomson (Lord Kelvin). Before 1968 it was called the degree Kelvin (°K). The kelvin is used as the unit of the International Practical Temperature Scale and is one of the fundamental units of the International System of Units. The kelvin is equal in magnitude to a degree Celsius (°C). kelvin[′kel·vən] (electricity) A name formerly given to the kilowatt-hour. Also known as thermal volt. (thermodynamics) A unit of absolute temperature equal to 1/273.16 of the absolute temperature of the triple point of water. Symbolized K. Formerly known as degree Kelvin. 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.KelvinA thermometer scale starting at absolute zero (approximately −273°C) and having degrees of the same magnitude as those of the Celsius thermometer. Thus, 0°C = 273 K. Named after first Lord Kelvin (1824–1907). Also called an absolute scale.kelvin the basic SI unit of thermodynamic temperature; the fraction 1/273.16 of the thermodynamic temperature of the triple point of water.
Kelvin William Thomson, 1st Baron Kelvin. 1824--1907, British physicist, noted for his work in thermodynamics, inventing the Kelvin scale, and in electricity, pioneering undersea telegraphy KelvinA 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).

SI units the units of measurement generally accepted for all scientific and technical uses; together they make up the International System of Units. (See also metric system" >metric system.) The abbreviation SI, from the French Système International d'Unités, is used in all languages. There are seven base SI units, defined by specified physical measurements, and two supplementary units. Units are derived for any other physical quantities by multiplication and division of the base and supplementary units. The derived units with special names are shown in the accompanying table.
SI is a coherent system. This means that units are always combined without conversion factors. The derived unit of velocity is the meter per second (m/s); the derived unit of volume is the cubic meter (m3). If you know that pressure is force per unit area, then you know that the SI unit of pressure (the pascal) is the unit of force divided by the unit of area and is therefore equal to 1 newton per square meter.
The metric prefixes can be attached to any unit in order to make a unit of a more convenient size. The symbol for the prefix is attached to the symbol for the unit, e.g., nanometer (nm) = 10−9 m. The units of mass are specified in terms of the gram, e.g., microgram (μg) = 10−9 kg.
Only one prefix is used with a unit; the use of units such as the millimicrometer is no longer acceptable. When a unit is raised to a power, the power applies to the prefix as well, e.g., a cubic millimeter (mm3) = 10−9 m3. When a prefix is used with a ratio unit, it should be in the numerator rather than in the denominator, e.g., kilometers/second (km/s) rather than meters/millisecond (m/ms). Only prefixes denoting powers of 103 are normally used. Hecto-, deka-, deci-, and centi- are usually attached only to the metric system units gram, meter, and liter.
Owing to the force of tradition, one noncoherent unit, the liter, equal to 10−3 m3, or 1 dm3, is generally accepted for use with SI. The internationally accepted abbreviation for liter is the letter l; however, this can be confused with the numeral 1, especially in typescript. For this reason, the capital letter L is also used as a symbol for liter. The lower case letter is generally used with prefixes, e.g., dl, ml, fl. The symbols for all other SI units begin with a capital letter if the unit is named after a person and with a lower case letter otherwise. The name of a unit is never capitalized.Kel·vin (kel'vĭn), William Thomson, Scottish physicist, 1824-1907. See: kelvin, Kelvin scale.
