1. What is an Electricity Consumption Calculator?

Definition: This calculator estimates the electricity consumption in kilowatt-hours (kWh) based on appliance power rating and usage time.

Purpose: It helps consumers estimate their electricity usage and costs, particularly for Meralco customers in the Philippines.

2. How Does the Calculator Work?

The calculator uses the formula:

Where:

• \( E \) — Electricity consumption (kWh)
• \( P \) — Power consumption (watts)
• \( t \) — Usage time (hours)

Explanation: The power in watts is multiplied by usage time in hours, then divided by 1000 to convert to kilowatt-hours.

3. Importance of Electricity Consumption Calculation

Details: Understanding electricity consumption helps in budgeting, energy conservation, and identifying high-consumption appliances.

4. Using the Calculator

Tips: Enter the appliance's power rating in watts and the duration of use in hours. All values must be > 0.

5. Frequently Asked Questions (FAQ)

Q1: Where can I find an appliance's power rating?
A: Check the label or manual of the appliance, or use a wattmeter to measure actual consumption.

Q2: How do I convert this to Meralco bill amount?
A: Multiply the kWh result by Meralco's current rate (check your bill for the exact rate).

Q3: What's the difference between watts and kilowatts?
A: 1 kilowatt = 1000 watts. Electricity bills are calculated in kilowatt-hours.

Q4: Can I calculate monthly consumption with this?
A: Yes, multiply daily usage by 30, or enter total monthly hours directly.

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