1. What is Monthly AC Power Consumption?

Monthly AC power consumption refers to the total electrical energy used by an AC-powered device or system over a 30-day period. It helps in estimating electricity costs and energy management for households and businesses.

2. How Does the Calculator Work?

The calculator uses the formula:

Where:

• \( E_{month} \) — Monthly energy consumption (kWh)
• \( P \) — Power rating of the device (kW)
• \( t_{daily} \) — Daily usage time (hours)

Explanation: The formula multiplies the device's power consumption by daily usage hours and then by 30 days to get the monthly total.

3. Importance of Energy Consumption Calculation

Details: Calculating monthly energy consumption is essential for budgeting electricity costs, identifying energy-efficient practices, and reducing carbon footprint through better energy management.

4. Using the Calculator

Tips: Enter the device's power rating in kilowatts (kW) and daily usage time in hours. Both values must be positive numbers (power > 0, daily time between 0-24 hours).

5. Frequently Asked Questions (FAQ)

Q1: How do I convert watts to kilowatts?
A: Divide the wattage by 1000 (1 kW = 1000W). For example, a 1500W device is 1.5 kW.

Q2: Why multiply by 30 days?
A: This assumes a standard 30-day month for consistent monthly billing calculations.

Q3: Does this account for varying electricity rates?
A: No, this calculates energy consumption only. Multiply the result by your electricity rate to estimate costs.

Q4: What if usage varies daily?
A: Use an average daily usage time for the most accurate monthly estimate.

Q5: Can this be used for DC devices?
A: While the formula works, this calculator is specifically designed for AC power consumption calculations.
