1. What is a kW to kWh Calculator?

Definition: This calculator converts power in kilowatts (kW) to energy in kilowatt-hours (kWh) based on time of operation.

Purpose: It helps determine electrical energy consumption for devices, systems, or entire facilities.

2. How Does the Calculator Work?

The calculator uses the formula:

Where:

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

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

3. Importance of Energy Calculation

Details: Accurate kWh calculations help with energy monitoring, cost estimation, and efficiency improvements.

4. Using the Calculator

Tips: Enter the power in kW and time in hours. Both values must be > 0. For minutes, divide by 60 (e.g., 30 min = 0.5 hours).

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 calculate monthly energy consumption?
A: Multiply daily kWh by number of operating days, or use hours per month (e.g., 24h × 30d = 720h).

Q3: Can I use this for appliances rated in watts?
A: Yes, just divide watts by 1000 to get kW (e.g., 1500W = 1.5kW).

Q4: How accurate is this calculation?
A: It assumes constant power draw. For variable loads, use average power or more complex calculations.

Q5: How do I estimate electricity costs from kWh?
A: Multiply kWh by your electricity rate (e.g., 100 kWh × $0.12/kWh = $12).
