Convert Amp hour to Watt hour (Ah to Wh)

Insert the Amp hours (Ah) and voltage (V) below and click on Calculate to obtain Watt hours (Wh).

Ah

V

Wh

Formula is (Ah)*(V) = (Wh). For example, if you have a 2 Ah battery rated at 5 V, the power is 2Ah * 5V = 10Wh.

Convert Watt hour to Amp hour (Wh to Ah)

Insert Watts-hour (Wh) and voltage (V) below and click on Calculate to obtain Amp-hours (Ah).

Wh

V

Ah

Formula is (Wh)/(V) =(Ah). For example, if you have a 10Wh battery rated at 5V, the current is 10Wh / 5V = 2Ah.
