1. What is a kWh per Day Calculator?

Definition: This calculator estimates daily energy consumption in kilowatt-hours (kWh) based on power consumption in kilowatts (kW).

Purpose: It helps homeowners, businesses, and energy professionals estimate daily electricity usage for appliances, systems, or entire facilities.

2. How Does the Calculator Work?

The calculator uses the formula:

\[ E_{kWh} = P_{kW} \times 24 \]

Where:

\( E_{kWh} \) — Energy consumption (kilowatt-hours)
\( P_{kW} \) — Power consumption (kilowatts)
24 — Hours in a day

Explanation: The power consumption in kW is multiplied by 24 hours to get total daily energy consumption in kWh.

3. Importance of Energy Calculation

Details: Accurate energy estimation helps with electricity budgeting, solar system sizing, and identifying energy-saving opportunities.

4. Using the Calculator

Tips: Enter the power consumption in kW (1 kW = 1000 watts). The value must be > 0.

5. Frequently Asked Questions (FAQ)

Q1: What if my device is rated in watts?
A: Convert watts to kW by dividing by 1000 (e.g., 1500W = 1.5kW).

Q2: Does this assume continuous 24-hour operation?
A: Yes, this calculates maximum possible consumption. For intermittent use, multiply by actual hours used.

Q3: How can I find my appliance's power consumption?
A: Check the nameplate or specifications, or use a wattmeter for actual measurements.

Q4: What's the difference between kW and kWh?
A: kW measures power (rate of energy use), kWh measures energy (power × time).

Q5: How do I calculate monthly consumption?
A: Multiply daily kWh by 30 (days) for a rough monthly estimate.
