1. What is the Watts to kWh Cost Calculator?

This calculator helps you determine the electricity cost of running electrical appliances in the Philippines. It converts power consumption in watts to kilowatt-hours (kWh) and calculates the cost based on current electricity rates.

2. How Does the Calculator Work?

The calculator uses the following formula:

Where:

• \( W \) — Power consumption in watts (W)
• \( h \) — Usage time in hours
• \( Cost/kWh \) — Electricity rate in Philippine Pesos per kilowatt-hour

Explanation: The formula first converts watts to kilowatts (by dividing by 1000), then multiplies by usage hours to get kWh, and finally multiplies by the cost per kWh to get the total cost.

3. Understanding Electricity Costs in the Philippines

Details: As of 2023, the average electricity rate in the Philippines ranges from PHP 8.00 to PHP 12.00 per kWh depending on the area and distribution utility. This calculator uses a default rate of PHP 9.99/kWh which can be adjusted to match your actual rate.

4. Using the Calculator

Tips:

• Find the wattage of your appliance (usually on the label or manual)
• Estimate your daily usage hours
• Use your actual electricity rate for most accurate results
• For monthly calculations, multiply daily usage by 30 or enter total monthly hours

5. Frequently Asked Questions (FAQ)

Q1: How do I find my appliance's wattage?
A: Check the label, manual, or manufacturer's website. If only amps are listed, multiply amps by voltage (usually 220V in PH) to get watts.

Q2: What's the difference between watts and kilowatts?
A: 1 kilowatt = 1000 watts. Electricity is typically billed per kilowatt-hour (kWh).

Q3: Why are Philippine electricity rates high?
A: Rates are affected by generation costs, transmission charges, taxes, and the country's reliance on imported fuels.

Q4: How can I reduce my electricity bill?
A: Use energy-efficient appliances, turn off unused devices, use natural light, and maintain your appliances properly.

Q5: Does this calculator account for all charges on my bill?
A: No, it calculates only the energy consumption cost. Your actual bill includes additional fees like distribution charges and taxes.
