Wh to mAh Calculator

Easily convert watt-hours (Wh) and voltage (V) to milliamp-hours (mAh). Enter the energy in Wh and voltage to get the battery capacity in mAh instantly.

Wh to mAh Formula

mAh = (Wh × 1000) / V

Example Calculations

10 Wh, 5 V → (10 × 1000) / 5 = 2000 mAh
20 Wh, 3.7 V → (20 × 1000) / 3.7 = 5405 mAh

Wh to mAh Table

Wh	V	mAh
10	5	2000
20	3.7	5405
