1. What is Daily Energy Consumption?

Definition: This calculator estimates the energy consumed by an electrical device over a 24-hour period.

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

2. How Does the Calculator Work?

The calculator uses the formula:

\[ E_{day} = \frac{P \times 24}{1000} \]

Where:

\( E_{day} \) — Daily energy consumption (kWh)
\( P \) — Power consumption (watts)

Explanation: The power in watts is multiplied by 24 hours and divided by 1000 to convert watt-hours to kilowatt-hours (kWh).

3. Importance of Energy Calculation

Details: Understanding daily energy consumption helps with budgeting electricity costs, sizing solar power systems, and identifying energy-efficient alternatives.

4. Using the Calculator

Tips: Enter the device's power consumption in watts (find this on the device label or specifications). The value must be > 0.

5. Frequently Asked Questions (FAQ)

Q1: How do I find my device's power consumption?
A: Check the device's label, manual, or specifications sheet for wattage information.

Q2: What if my device has variable power?
A: Use the average power consumption or calculate separately for different modes.

Q3: How can I estimate monthly costs from this?
A: Multiply daily kWh by 30 and then by your electricity rate per kWh.

Q4: Why divide by 1000?
A: To convert from watt-hours (Wh) to kilowatt-hours (kWh), the standard unit for electricity billing.

Q5: Does this account for standby power?
A: No, this calculates continuous operation. For accurate results, measure actual usage with an energy monitor.
