Watt-hour (Wh) Calculator
Let’s calculate Watt-hours (Wh) based on given inputs such as mAh, Ah, Voltage (V), or Watts & Time.
Calculate Watt-hours from Amp-hours
To calculate watt-hours from amp-hours, you can use the following formula:
Wh = Ah × VWhere:
- Wh = Watt-hours
- Ah = Ampere-hours
- V = Voltage (in volts)
For example, if you have a battery rated at 10 Ah and operates at 12V, the calculation would be:
Wh = 10 Ah × 12 = 120 WhCalculate Watt-hours from Time
To calculate watt-hours based on power consumption over time, use the following formula:
Wh = W × hWhere:
- Wh = Watt-hours
- W = Power in watts
- h = Time in hours
For example, if you run a 100-watt appliance for 3 hours, the calculation would be:
Wh = 100 W × 3 h = 300 WhWhat is a Watt-hour (Wh)?
A watt-hour (Wh) is a unit of energy that measures the amount of work done or energy consumed over time. It represents the energy used when one watt of power is consumed for one hour. For example, a 60-watt light bulb running for one hour uses 60 Wh of energy.
Watt-hour (Wh) Calculator
Our Watt-hour (Wh) Calculator provides an easy way to calculate energy consumption based on two methods:
| Option | Description | Formula |
|---|---|---|
| 1. Watt-hours from Amp-hours | Calculate Watt-hours based on the capacity in Amp-hours and the voltage of the system. | Wh = Ah × V |
| 2. Watt-hours from Time | Calculate Watt-hours based on the power in Watts and the time in hours. | Wh = Power × Time |
