Celsius heat units (IT) per second to kilowatts conversion calculator shown above calculates how many kilowatts are in 'X' Celsius heat units (IT) per second (where 'X' is the number of Celsius heat units (IT) per second to convert to kilowatts). In order to convert a value from Celsius heat units (IT) per second to kilowatts (from CHU/s to kW) just type the number of CHU/s to be converted to kW and then click on the 'convert' button.
