1. What is an Electric kWh Calculator?

Definition: This calculator determines the amount of electricity consumed by calculating the difference between current and previous meter readings.

Purpose: It helps homeowners and businesses track their electricity usage between billing periods.

2. How Does the Calculator Work?

The calculator uses the formula:

Where:

• \( kWh \) — Kilowatt-hours of electricity used
• \( Current\ Reading \) — Present meter reading (kWh)
• \( Previous\ Reading \) — Last recorded meter reading (kWh)

Explanation: The simple subtraction gives the actual electricity consumption between two measurement periods.

3. Importance of kWh Calculation

Details: Accurate kWh calculation helps monitor energy usage, verify utility bills, and identify potential energy-saving opportunities.

4. Using the Calculator

Tips: Enter both meter readings in kWh. Current reading should be equal to or greater than previous reading.

5. Frequently Asked Questions (FAQ)

Q1: Where can I find my meter readings?
A: Check your electric meter display - digital meters show kWh directly, while analog meters require reading the dials.

Q2: How often should I calculate my kWh usage?
A: Monthly calculations help track seasonal variations and detect unusual consumption patterns.

Q3: What if my current reading is less than previous?
A: This typically indicates a meter reset or replacement. Contact your utility provider for clarification.

Q4: Can I estimate my electricity cost from kWh?
A: Yes, multiply kWh by your utility's rate per kWh (found on your bill) to estimate costs.

Q5: Why is my actual usage different from the bill?
A: Bills may include estimated readings or different calculation periods. Always compare using actual readings.
