开尔文

开尔文勋爵,该单位的同名人物

开尔文英语:Kelvin)是温度的计量单位。它是国际单位制(SI)的七个基本单位之一,符号为K。以开尔文计量的温度标准称为热力学温标,其零点为绝对零度。在热力学的经典表述中,绝对零度下所有热运动停止。1开尔文定义为水的三相点与绝对零度相差的273.16。水的三相点是0.01°C,因此温度变化1摄氏度,相当于变化了1开尔文。

开氏温标得名自爱尔兰工程师和物理学家威廉·汤姆森,第一代开尔文男爵(1824–1907)。

Kelvin 开尔文

Lord Kelvin, the namesake of the unit
A thermometer calibrated in degrees Celsius (left) and kelvins (right).

The kelvin is a unit of measure for temperature based upon an absolute scale. It is one of the seven base units in the International System of Units (SI) and is assigned the unit symbol K. The Kelvin scale is an absolute, thermodynamic temperature scale using as its null point absolute zero, the temperature at which all thermal motion ceases in the classical description of thermodynamics. The kelvin is defined as the fraction 273.16 of the thermodynamic temperature of the triple point of water (exactly 0.01 °C or 32.018 °F). In other words, it is defined such that the triple point of water is exactly 273.16 K.
