1. What is MWh?

MWh (Megawatt-hour) is a unit of energy representing one megawatt of power sustained for one hour. It's commonly used to measure electricity production and consumption.

2. How Does the Calculator Work?

The calculator uses the simple formula:

Where:

• \( MW \) — Power in megawatts
• \( Hours \) — Time duration in hours

Explanation: Energy is power multiplied by time. One MWh equals one megawatt of power produced or consumed continuously for one hour.

3. Importance of MWh Calculation

Details: MWh is crucial for energy billing, power plant output measurement, and understanding electricity consumption patterns.

4. Using the Calculator

Tips: Enter power in megawatts (MW) and time duration in hours. Both values must be positive numbers.

5. Frequently Asked Questions (FAQ)

Q1: What's the difference between MW and MWh?
A: MW measures power (rate of energy use), while MWh measures energy (total amount used over time).

Q2: How many homes can 1 MWh power?
A: Approximately 330 US homes for one hour, or one typical home for about two weeks.

Q3: How do you convert MWh to kWh?
A: Multiply by 1000 (1 MWh = 1000 kWh).

Q4: What's a typical MWh consumption for a household?
A: Average US household uses about 10-12 MWh per year.

Q5: How does this relate to carbon emissions?
A: Emissions depend on energy source - about 0.4-1 metric ton CO2 per MWh for fossil fuel plants.
