Kelvin (K) | Definition & Facts | Britannica
网页Kelvin, base unit of thermodynamic temperature measurement in the International System of Units (SI). It is the fundamental unit of the Kelvin scale and has as its zero point absolute zero (−273.15 degrees on the Celsius temperature scale and −459.67 degrees on the Fahrenheit temperature scale).
Kelvin to Celsius (K to °C) conversion calculator
网页Kelvin is an absolute temperature measurement defined in the International System of Units (SI). It is named after the Scottish physicist William Thomson (Lord Kelvin) who studied the field of thermodynamics. The Kelvin scale is based on absolute zero; the point at which all molecular motion ceases.

网页2018年5月14日 · The kelvin (K) — the SI unit of temperature — now has a radically new definition. In daily life, the Kelvin temperature scale — named for the celebrated British physicist Lord Kelvin (1824–1907) — rarely makes an appearance.
Kelvin Definition & Meaning - Merriam-Webster
网页The meaning of KELVIN is the base unit of temperature in the International System of Units that is defined by setting the fixed numerical value of the Boltzmann constant to be 1.380649 x 10—23 joules per kelvin and that is equal to 1/273.16 of the Kelvin scale temperature of the triple point of water —abbreviation K.
William Thomson, Baron Kelvin | Biography & Facts | Britannica
网页2024年9月3日 · William Thomson, Baron Kelvin (born June 26, 1824, Belfast, County Antrim, Ireland [now in Northern Ireland]—died December 17, 1907, Netherhall, near Largs, Ayrshire, Scotland) was a Scottish engineer, mathematician, and physicist who profoundly influenced the scientific thought of his generation.
Kelvin to Fahrenheit (K to °F) - Metric Conversion
网页To convert from Kelvin to Fahrenheit, you can use the following formula: °F = ( (K - 273.15) × 9/5) + 32. First, subtract 273.15 from the given temperature in Kelvin, this gives the Celsius value. This step is necessary because the zero point on the Kelvin scale is equivalent to -273.15°C.
