Conversion Formula
$$T_{°C} = T_{K} - 273.15$$
Subtract 273.15 from Kelvin to get Celsius.

K to °C in Engineering
Temperature conversions are fundamental across all engineering disciplines. Celsius and Fahrenheit are used for everyday measurements, while Kelvin is required for thermodynamic calculations and Rankine for US customary thermodynamic systems.
Kelvin: SI base unit of temperature. Absolute thermodynamic scale starting at absolute zero. Required for gas law and thermodynamic calculations.
Degree Celsius: International standard temperature scale. Water freezes at 0°C and boils at 100°C under standard conditions.
