1. What is Watts Per Hour?

Watts per hour (Wh) is a unit of energy equivalent to one watt (1 W) of power expended for one hour (1 h) of time. It measures energy consumption or production over time.

2. How Does the Calculator Work?

The calculator uses the simple formula:

Where:

• \( Wh \) — Watts per hour (energy)
• \( P \) — Power in watts
• \( t \) — Time in hours

Explanation: The formula multiplies power consumption by time to calculate total energy used.

3. Importance of Watts Per Hour Calculation

Details: Calculating watt-hours helps estimate energy consumption, calculate electricity costs, and compare energy efficiency of devices.

4. Using the Calculator

Tips: Enter power in watts and time in hours. Both values must be positive numbers. The calculator will compute the energy consumption in watt-hours.

5. Frequently Asked Questions (FAQ)

Q1: What's the difference between watts and watt-hours?
A: Watts measure power (rate of energy use), while watt-hours measure energy (power × time).

Q2: How do I convert watt-hours to kilowatt-hours?
A: Divide watt-hours by 1000 (1 kWh = 1000 Wh).

Q3: Is this the same as watts per hour (W/h)?
A: No, watt-hours (Wh) measure energy, while watts per hour (W/h) measure change in power over time.

Q4: How accurate is this calculation?
A: It's accurate for constant power consumption. For variable power, you'd need to integrate power over time.

Q5: Can I use this for solar panel calculations?
A: Yes, it works for both energy consumption and production calculations.
