Understanding Watt-Hours to Amp-Hours Conversion

What are Watt-Hours (Wh)?

Watt-hours measure electrical energy consumption or battery capacity. One watt-hour represents one watt of power sustained for one hour.

What are Amp-Hours (Ah)?

Amp-hours measure electrical charge capacity, commonly used for batteries. One amp-hour equals one ampere of current flowing for one hour.

Conversion Formula

Amp-Hours (Ah) = Watt-Hours (Wh) ÷ Voltage (V)
