📌 Standard Benchmark Reference Values
-273.15 °C=0 K
Absolute zero (thermodynamic minimum).
Exact Ratio0.01 °C=273.16 K
Triple point of water.
Exact Ratio摂氏度 (°C)
The Celsius scale is defined so that 0 °C is the freezing point of water and 100 °C is the boiling point of water at standard atmospheric pressure.
ケルビン (K)
The kelvin is the SI base unit of thermodynamic temperature. It is defined by setting the Boltzmann constant to exactly 1.380649 × 10⁻²³ J/K. 0 K is absolute zero.
