You mean this one?

 

Celsius heat unit (Chu)

a unit of heat energy equal to the energy required to raise the temperature of one pound of water by 1�C at standard atmospheric pressure. 1 Chu is equal to exactly 1.8 Btu, approximately 453.59 IT calories (see above), or 1.8991 kilojoules. The unit is also called the centigrade heat unit.
