1. What is MW to TWh Conversion?

The MW to TWh conversion calculates the total energy produced or consumed over time. While megawatts (MW) measure power (the rate of energy transfer), terawatt-hours (TWh) measure energy (the total amount of power consumed or produced over time).

2. How Does the Calculator Work?

The calculator uses the following equation:

Where:

• \( MW \) — Power in megawatts
• \( Hours \) — Time duration in hours
• \( 1,000,000 \) — Conversion factor (1 terawatt = 1,000,000 megawatts)

Explanation: The equation converts power (MW) to energy (TWh) by multiplying by time and dividing by the conversion factor between megawatts and terawatts.

3. Importance of Energy Conversion

Details: This conversion is essential for energy planning, comparing power plant outputs, calculating electricity generation over time, and understanding large-scale energy consumption.

4. Using the Calculator

Tips: Enter power in megawatts (MW) and time duration in hours. Both values must be positive numbers. The calculator will output the equivalent energy in terawatt-hours (TWh).

5. Frequently Asked Questions (FAQ)

Q1: Why convert MW to TWh?
A: MW measures instantaneous power, while TWh measures total energy over time, which is more meaningful for annual energy production or consumption comparisons.

Q2: How many TWh is 1000 MW for a year?
A: 1000 MW × 8760 hours / 1,000,000 = 8.76 TWh (assuming continuous operation for one year).

Q3: What's the difference between MW and MWh?
A: MW is power (rate of energy), MWh is energy (power × time). 1 MW running for 1 hour = 1 MWh.

Q4: How accurate is this conversion?
A: The conversion is mathematically exact. Accuracy depends on the precision of your input values.

Q5: Can I convert TWh back to MW?
A: Yes, if you know the time period: MW = (TWh × 1,000,000) ÷ hours.
