mAh to Wh Calculator

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

mAh to Wh Formula

• Wh = mAh × V ÷ 1000

Example Calculations

• 2000 mAh, 3.7 V → 2000 × 3.7 ÷ 1000 = 7.4 Wh
• 5000 mAh, 5 V → 5000 × 5 ÷ 1000 = 25 Wh
