1. What is kWh Calculator from kW?

Definition: This calculator converts power in kilowatts (kW) to energy in kilowatt-hours (kWh) by factoring in the time duration.

Purpose: It helps determine electrical energy consumption for billing, system sizing, or energy monitoring purposes.

2. How Does the Calculator Work?

The calculator uses the formula:

Where:

• \( E \) — Energy (kWh)
• \( P \) — Power (kW)
• \( t \) — Time (hours)

Explanation: Energy equals power multiplied by time. 1 kWh equals 1 kW of power used continuously for 1 hour.

3. Importance of kWh Calculation

Details: Accurate kWh calculations are essential for electricity billing, solar system sizing, generator capacity planning, and energy efficiency assessments.

4. Using the Calculator

Tips: Enter the power consumption in kW and the operating time in hours. Both values must be positive numbers.

5. Frequently Asked Questions (FAQ)

Q1: What's the difference between kW and kWh?
A: kW measures power (rate of energy use), while kWh measures energy (total consumption over time).

Q2: How do I convert watts to kW for this calculator?
A: Divide watts by 1000 (1 kW = 1000W). Enter the kW value in the calculator.

Q3: Can I use minutes instead of hours?
A: Yes, but convert minutes to hours (divide by 60) before entering the value.

Q4: What if my device cycles on and off?
A: Use average power consumption over the total time period or calculate for each operating cycle separately.

Q5: How accurate is this calculation?
A: It's theoretically exact for constant power draw. For variable loads, it gives an estimate.
