1. What Is Electric Consumption?

Electric consumption refers to the amount of electrical energy used by an appliance or device over a specific period of time, typically measured in kilowatt-hours (kWh).

2. How Does The Calculator Work?

The calculator uses the electric consumption formula:

Where:

• \( Power \) — Electrical power consumption in watts (W)
• \( Time \) — Duration of usage in hours (h)
• \( 1000 \) — Conversion factor from watts to kilowatts

Explanation: This formula calculates the total energy consumption by multiplying power rating by time and converting to kilowatt-hours.

3. Importance Of Consumption Calculation

Details: Calculating electric consumption helps in understanding energy usage patterns, estimating electricity costs, and identifying opportunities for energy savings and efficiency improvements.

4. Using The Calculator

Tips: Enter the power rating in watts and the usage time in hours. Both values must be positive numbers. The calculator will provide the consumption in kilowatt-hours.

5. Frequently Asked Questions (FAQ)

Q1: What's the difference between watts and kilowatt-hours?
A: Watts measure power (rate of energy use), while kilowatt-hours measure energy consumption (power × time).

Q2: How can I find the power rating of my appliance?
A: Check the manufacturer's label, specification sheet, or user manual. Most appliances display their power rating in watts.

Q3: Why divide by 1000 in the formula?
A: We divide by 1000 to convert from watt-hours to kilowatt-hours, which is the standard unit for electricity billing.

Q4: Can I use this for multiple appliances?
A: Yes, calculate consumption for each appliance separately and sum the results for total consumption.

Q5: How accurate is this calculation?
A: The calculation provides an estimate. Actual consumption may vary based on appliance efficiency, usage patterns, and power fluctuations.
