How to convert watt-hours (Wh) to Ampere-hour (Ah)?
- Watt-hour (Wh): A watt-hour is a unit of energy that expresses the amount of energy consumed or produced at 1 watt (W) of power in 1 hour. It is commonly used to measure large-scale electrical energy, such as batteries, electrical energy storage systems, and power consumption. Relationship to joules: 1 Wh = 3600 joules (J), since 1 watt = 1 joule per second and 1 hour = 3600 seconds.
- Ampere-hour (Ah): The ampere-hour is a unit of electrical charge and represents the amount of electrical energy transferred through a current of 1 ampere (A) in 1 hour. It is used to measure the capacity of batteries, especially those used in portable electronic devices such as cell phones and laptops. Relationship to milliampere-hour: 1 Ah = 1000 milliampere-hours (mAh), since “milli” means one thousandth.
1. Wh to mAh Formula:
Ampere-hour (Ah) = Watt hours (Wh)/ Voltage (V)
2. conversely
Wh = Ah * Volt
