1. What is a Kilowatt Hours per Day Calculator?

Definition: This calculator estimates daily energy consumption in kilowatt-hours based on power rating and daily usage time.

Purpose: It helps homeowners and businesses understand their electricity usage patterns and estimate energy costs.

2. How Does the Calculator Work?

The calculator uses the formula:

Where:

• \( E_{kWh} \) — Energy consumption (kilowatt-hours per day)
• \( P_{kW} \) — Power consumption (kilowatts)
• \( t_{day} \) — Daily usage time (hours per day)

Explanation: The power rating multiplied by the hours of use gives the total energy consumed in a day.

3. Importance of Energy Calculation

Details: Understanding daily energy consumption helps with budgeting electricity costs, sizing solar systems, and identifying energy-saving opportunities.

4. Using the Calculator

Tips: Enter the appliance/device power in kW (1 kW = 1000W) and the average daily usage time in hours. All values must be > 0.

5. Frequently Asked Questions (FAQ)

Q1: How do I convert watts to kilowatts?
A: Divide watts by 1000 (e.g., 1500W = 1.5kW).

Q2: Can I calculate monthly consumption with this?
A: Multiply the daily result by 30 for a monthly estimate.

Q3: What's a typical power rating for household appliances?
A: Refrigerators: 0.1-0.2kW, AC units: 1-3.5kW, LED bulbs: 0.01-0.02kW.

Q4: How accurate is this calculation?
A: It provides theoretical consumption. Actual usage may vary based on efficiency and usage patterns.

Q5: How can I reduce my kWh consumption?
A: Use energy-efficient appliances, reduce usage time, and maintain equipment properly.
