1. What is the Watts to kWh Conversion?

The Watts to kWh conversion calculates energy consumption by converting power (in watts) over time (in hours) to kilowatt-hours, the standard unit of energy used by electric utilities.

2. How Does the Calculator Work?

The calculator uses the simple formula:

\[ kWh = \frac{P \times h}{1000} \]

Where:

Explanation: One kilowatt-hour equals 1,000 watts of power used for one hour. This conversion is essential for understanding electricity consumption and costs.

3. Importance of Energy Calculation

Details: Calculating kWh helps estimate electricity costs, compare appliance efficiency, and understand energy usage patterns for better energy management.

4. Using the Calculator

Tips: Enter power consumption in watts and duration in hours. For devices with variable power, use average wattage. All values must be positive numbers.

5. Frequently Asked Questions (FAQ)

Q1: How do I find my appliance's wattage?
A: Check the label or manual. If only amps and volts are listed, multiply them (Watts = Amps × Volts).

Q2: What's the difference between watts and kWh?
A: Watts measure power (rate of energy use), while kWh measures energy (power × time).

Q3: How much does 1 kWh cost?
A: Costs vary by location and provider. Check your electricity bill for your rate (typically $0.10-$0.30 per kWh).

Q4: Can I calculate monthly energy use with this?
A: Yes. Multiply daily kWh by 30, or calculate based on average daily usage hours.

Q5: Why divide by 1000?
A: To convert watt-hours (Wh) to kilowatt-hours (kWh), the standard billing unit (1 kWh = 1000 Wh).
