Watt-Hour to Hour Calculator
To convert Watt-hours (Wh) to Hours (h), use the formula:
Method 1: Using Power (W)
The relationship between watt-hours and hours can be expressed as:
Hours = Wh ÷ WWhere:
- Wh = Watt-hours
- W = Power in watts
Example Calculation
If you have a battery rated at 100 Wh and a device that uses 25 W, the calculation would be:
Hours = 100 Wh ÷ 25 W = 4 hoursMethod 2: Using Voltage and Current
The relationship can also be expressed as:
Hours = Wh ÷ (V × A)Where:
- Wh = Watt-hours
- V = Voltage (in volts)
- A = Current (in amperes)
Example Calculation
If you have a battery rated at 100 Wh, operates at a voltage of 12V, and the device draws 2A, the calculation would be:
Hours = 100 Wh ÷ (12V × 2A) = 4.17 hoursWatt-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.
Power (W)
Power (W) is the rate at which energy is used or produced. It is measured in watts and indicates how much energy is consumed by a device in one hour.
Voltage (V)
Voltage (V) is the electrical potential difference between two points in a circuit. It is the force that pushes electric charges through a conductor.
Current (A)
Current (A) is the flow of electric charge in a circuit. It is measured in amperes (A) and indicates how much electricity is flowing.
