Convert Amp hours to Watts (Ah to W)

Insert the Amp hours (Ah), voltage (V) and time in hours (h) below and click on Calculate to obtain Watts (W).
The formula is (Ah)*(V)/(h) = (W). For example, if you have a 2 Ah battery rated at 5 Volts that lasts for 2 hours, the wattage is 2Ah * 5V / 2h = 5W.
