Q = kJ/s = kW. Once you've calculated the Q in kW, you also can multiply it by 3412 to convert it into btu/hr and then divide it by 12000 to convert it into TR. Else, you also can divide the kW by 3.52 (12000 ÷ 3412 = 3.52) to convert it into TR. btu/hr = kW x 3412 TR = btu/hr ÷ 12000 TR = kW ÷ 3.52
