1. What is a Kilowatt per Hour Calculator?

Definition: This calculator estimates the electricity cost per hour based on power consumption in kilowatts and the cost per kilowatt-hour.

Purpose: It helps consumers and businesses estimate their electricity expenses for appliances or equipment.

2. How Does the Calculator Work?

The calculator uses the formula:

Where:

• \( C \) — Cost per hour (Philippine Pesos)
• \( P_{kW} \) — Power consumption (kilowatts)
• \( C_{kWh} \) — Cost per kilowatt-hour (₱/kWh)

Explanation: The power consumption is multiplied by the electricity rate to determine hourly operating cost.

3. Importance of Electricity Cost Calculation

Details: Understanding electricity costs helps with budgeting, comparing appliance efficiency, and managing energy consumption.

4. Using the Calculator

Tips: Enter the power consumption in kW and the cost per kWh (default 11.43 ₱/kWh, the average rate in the Philippines). All values must be > 0.

5. Frequently Asked Questions (FAQ)
