Electrical Power calculator

Calculate power (Watt)

Potential ?3.8 V (Volt)
Current ?15.71 A (Ampere)A = C/s
Resistance ?0.24 Ω (Ohm)Ω = V / A
Active power ?59.7 W (Watt)rate of energy transfer / W = V * A

Calculate energy (KWh/Joule)

After 1 hours of continuous power usage:

Charge (Ah)15.71 Ah
Energy (kWh)59.7 Wh
Energy (Joule)214.93 MJ
Energy (Calorie)51.33 Mcal

Calculate capacity (mAh/Wh)

Compare capacity with [AA batteries] [Powerpack] [Phone]
