Zero kelvin (−273.15 °C) is defined as absolute zero. Absolute zero is the coldest point on the thermodynamic temperature scale, a state at which the enthalpy and entropy of a cooled ideal gas reach their minimum value.

The kelvin (symbol: K) is the base unit for temperature in the International System of Units (SI).

开尔文（Kelvins），为热力学温标或称绝对温标，是国际单位制中的温度单位。开尔文温度常用符号K表示，其单位为开。每变化1K相当于变化1℃，计算起点不同。摄氏度以冰水混合物的温度为起点，而开尔文是以绝对零度作为计算起点，即-273.15℃=0K。

2020年8月10日 · Absolute zero is 0 K, -273.15 °C, or -459.67 °F. Absolute zero is defined as the temperature at which a cooled ideal gas is in its lowest energy state. In other words, it’s the point at which no more heat can be removed.

2010年2月17日 · But scientists found that molecules at frigid temperatures just a few hundred billionths of a degree above absolute zero (−273.15°C or 0 kelvin) can still exchange atoms, forging new chemical...

开尔文的零点是绝对零度，即理论上分子运动停止的温度，约为 -273.15 °C。 开尔文的单位符号为 K。 摄氏度是另一种常用的温度单位，广泛应用于日常生活和许多科学领域。 摄氏度的零点是水的冰点（0 °C），而100 °C是水的沸点。 摄氏度单位的符号为 °C。 摄氏度和开尔文之间的关系使得它们互补，方便进行科学计算。 在开尔文 (K) 和摄氏度 (°C) 之间进行转换时，可以使用以下公式： 通过这些公式和示例，你可以轻松地在开尔文 (K) 和摄氏度 (°C) 之间进行转换。 开尔文 (K) …

2025年3月1日 · 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).

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.

Here is the Kelvin to Celsius conversion. Tc = T – 273.15. The Kelvin scale is designed so one Celsius degree and one kelvin are exactly the same. The following are the list of conversion formulas. Three scales are used to measure temperature: the …
