## What is Celsius heat unit (IT)?

The **Celsius heat unit (IT)** is a unit of energy or work equal to 1,899.1005347 joules (1 CHU = 1,899.1005347 J), the SI derived unit of energy. It is also equal to 1.8991005347 kilojoules (kJ), or 453.895921 calories (thermochemical) (cal), or 0.453895921 kilocalories (thermochemical) (kcal), or 1.8 British thermal units (IT) (BTU), or 0.5275279 watt hours (Wh) or 0.0005275279 kilowatt hours (kWh).

The Celsius heat unit is the energy required to increase the temperature of one pound of water by one degree Celsius (or 1.8 degrees Fahrenheit) at a constant pressure of one atmosphere. One Celsius heat unit is equal to 1.8 British thermal units (1 CHU = 1.8 BTU).
