1. What is a Watts To kWh Cost Calculator?

Definition: This calculator estimates the electricity cost in Philippine Pesos based on appliance wattage, usage time, and current electricity rate.

Purpose: It helps Filipino households and businesses estimate their electricity expenses for better budgeting and energy conservation.

2. How Does the Calculator Work?

The calculator uses the formula:

Where:

• \( Cost \) — Electricity cost (Philippine Pesos)
• \( Watts \) — Power consumption of appliance (watts)
• \( Hours \) — Usage time (hours)
• \( Rate \) — Electricity rate (PHP per kWh)

Explanation: The formula converts watts to kilowatt-hours (kWh) then multiplies by the current electricity rate to get the cost.

3. Importance of Electricity Cost Calculation

Details: Understanding electricity costs helps in budgeting, identifying energy-hungry appliances, and making informed decisions about energy usage.

4. Using the Calculator

Tips: Enter the appliance wattage (check label or manual), usage time in hours, and current electricity rate (default 9.50 PHP/kWh). All values must be > 0.

5. Frequently Asked Questions (FAQ)

Q1: What's the current electricity rate in the Philippines?
A: As of 2023, rates average 9.50 PHP/kWh but vary by provider and location. Check your Meralco bill for exact rates.

Q2: How do I find my appliance's wattage?
A: Check the appliance label, manual, or manufacturer website. Alternatively, use a wattage meter for accurate measurement.

Q3: Does this include all charges on my bill?
A: No, this calculates only energy consumption cost. Your actual bill includes additional fees like distribution charges and taxes.

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

Q5: What's the difference between watts and kilowatt-hours?
A: Watts measure power (energy per second), while kilowatt-hours measure energy consumption over time (power × time).
