... (J), where 1 Btu = 1055 J. The rate of heat loss is thermal power PT, which is measured in Btu’s per second or joules per second. Since one joule per second is one watt (W), 1 Btu/s = 1055 J/s = 1055 W, 3600 Btu/hr = 1055 W, 3.41 Btu/hr = 1 W. We calculate the thermal power radiated by a hot body as ...
