Watts per hour is not a valid unit of measurement. Watts (W) measure power, which is the rate at which energy is used. Hours (h) measure time.
Here's why:
- Power (Watts): Represents the rate at which energy is consumed or produced. Think of it as the speed at which you use energy.
- Energy (Watt-hours): Represents the total amount of energy used or produced over a specific time. Think of it as the total distance you travel.
Therefore, "watts per hour" is like saying "miles per hour per hour," which doesn't make sense.
Here's how you can relate power and energy:
- Energy (Wh) = Power (W) x Time (h)
Example:
If a device uses 100 watts of power for 2 hours, it consumes 200 watt-hours of energy.
Remember:
- Watts measure the rate of energy usage.
- Watt-hours measure the total amount of energy used.
