1. What is kWh Calculation?

The kWh (kilowatt-hour) calculation measures energy consumption by multiplying power in kilowatts (kW) by time in hours. It's the standard unit for electricity billing and energy monitoring.

2. How Does the Calculator Work?

The calculator uses the basic energy formula:

Where:

• \( \text{kW} \) — Power in kilowatts
• \( \text{Hours} \) — Time duration in hours

Explanation: One kilowatt-hour represents the energy consumed by a 1,000-watt appliance running for one hour.

3. Importance of kWh Calculation

Details: Understanding kWh helps in estimating electricity costs, comparing appliance efficiency, and managing energy consumption patterns.

4. Using the Calculator

Tips: Enter power in kilowatts (1 kW = 1000 watts) and time in hours. For minutes, convert to hours (30 min = 0.5 hours).

5. Frequently Asked Questions (FAQ)

Q1: How do I convert watts to kW?
A: Divide watts by 1000 (e.g., 1500W = 1.5 kW).

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

Q3: How can I estimate my electricity bill?
A: Multiply kWh by your electricity rate (e.g., 100 kWh × $0.12/kWh = $12).

Q4: What's a typical kWh usage for a home?
A: Average US home uses about 900 kWh/month, but varies by size, appliances, and climate.

Q5: How accurate is this calculation?
A: Perfectly accurate for constant power draw. For variable loads, use average power over time.
