Calculate temperature from watts
WebYou can use the following formula to determine your required wattage. kW = (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 … Web1 BTU/h = 0.2931 watt. Horsepower: Horsepower (hp) is a unit of power most commonly used to reference the output of engines or motors. There are a number of different definitions of horsepower. Two of them are mechanical horsepower and metric horsepower. 1 unit of mechanical horsepower = 745.7 watts. 1 unit of metric horsepower = 735.5 watts
