What do you mean by "per hour"? Watt is a measure of power, that is a rate: Joule/second, [energy/time] > The watt (symbol: W) is the unit of power or radiant flux in the International System of Units (SI), equal to 1 joule per second or 1 kg⋅m2⋅s−3.[1][2][3] It is used to quantify the rate of energy transfer. https://en.wikipedia.org/wiki/Watt https://en.wikipedia.org/wiki/Watt
