Understanding Watt-Hours to Milliamp-Hours Conversion
What are Watt-Hours (Wh)?
Watt-hours (Wh) measure energy capacity in batteries and other power storage devices. One watt-hour represents the energy needed to sustain one watt of power for one hour.
What are Milliamp-Hours (mAh)?
Milliamp-hours (mAh) measure electrical charge capacity. One milliamp-hour equals the charge transferred by a current of one milliampere flowing for one hour.
Conversion Formula
mAh = (Wh × 1000) ÷ V
