Ah to W mAh to Wh mAh to mWh Other

Convert Amp-hours to hours (Ah to h)

You can obtain the time that a battery will last if you know the Amp-hours as well as the Amps. Insert the Amp-hours (Ah) and Amps (A) below and click on Calculate to obtain the time in hours (h).
The formula is (Ah)/(A) = (h). For example, if you have a 6 Ah battery that runs at 2 Amps, the time duration is 6Ah / 2A = 3 hours.
