1. What is Megawatt-hour (MWh)?

A megawatt-hour (MWh) is a unit of energy equivalent to one megawatt (1 MW) of power expended for one hour (1 h) of time. It is commonly used to measure electricity production and consumption on a large scale.

2. How Does the Calculator Work?

The calculator uses the simple formula:

Where:

• \( MW \) — Power in megawatts
• \( Hours \) — Time duration in hours
• \( MWh \) — Energy in megawatt-hours

Explanation: This calculation converts power (the rate of energy use) into energy (the total amount used over time).

3. Importance of MWh Calculation

Details: MWh calculations are essential for energy billing, grid management, renewable energy project planning, and understanding electricity consumption patterns for large facilities and utilities.

4. Using the Calculator

Tips: Enter power in megawatts (MW) and time in hours. Both values must be positive numbers. The calculator will compute the total energy in megawatt-hours.

5. Frequently Asked Questions (FAQ)

Q1: How many kilowatt-hours are in a megawatt-hour?
A: 1 MWh = 1,000 kWh (kilowatt-hours)

Q2: What's the difference between MW and MWh?
A: MW measures power (rate of energy use), while MWh measures energy (total consumption over time).

Q3: How much electricity does 1 MWh represent?
A: 1 MWh can power approximately 330 homes for one hour (US average) or an average EV for about 3,700 miles of driving.

Q4: Can I calculate for minutes instead of hours?
A: Yes, but first convert minutes to hours (divide by 60). For example, 30 minutes = 0.5 hours.

Q5: How is MWh used in electricity billing?
A: Utilities typically charge large consumers based on MWh usage, with rates that may vary by time of day and season.
