mah_to_wh
shallowengineer.calc/calc · Verify this server
Converts battery capacity from milliamp-hours (mAh) to watt-hours (Wh), kilowatt-hours (kWh), and joules (J) given the nominal cell voltage. This is the most common battery unit conversion needed when comparing cells rated in mAh (e.g. 18650, AA) against energy budgets specified in Wh. Essential for airline lithium battery compliance (100 Wh limit for carry-on), solar battery bank sizing, and UPS capacity planning. Echoes back input values for easy chaining into battery_life, solar_sizing, and ups_runtime tools.
