WebWe assume you are converting between kilowatt hour and celsius heat unit. You can view more details on each measurement unit: kWh or celsius heat unit The SI derived unit for … WebkW = (WT x Cp x Δ T)/3412 x h. Where: kW = your kilowatt requirement. WT= the weight of the material to be heated, in lbs. Cp = the specific heat of the material to be heated, in BTU/lb°F. Δ T = Temperature Rise, in °F. 3412 = Conversion Factor, BTU/kWh. h = how long it should take to reach the temperature set point, in hours.
