1. What is MWh and kWh?

A kilowatt-hour (kWh) is a unit of energy equal to one kilowatt (1 kW) of power expended for one hour. A megawatt-hour (MWh) is equal to 1,000 kilowatt-hours and is typically used for larger-scale energy measurements.

2. How Does the Conversion Work?

The conversion formula is simple:

Where:

• \( kWh \) — Kilowatt-hours
• \( MWh \) — Megawatt-hours

Explanation: Since "mega" denotes a factor of one million (10^6) and "kilo" denotes a factor of one thousand (10^3), converting from kWh to MWh requires dividing by 1,000.

3. Practical Applications

Details: This conversion is commonly used in energy production, utility billing, and large-scale energy consumption measurements where MWh is the more practical unit.

4. Using the Calculator

Tips: Simply enter the kilowatt-hour value you want to convert. The calculator will automatically compute the equivalent megawatt-hours.

5. Frequently Asked Questions (FAQ)

Q1: Why convert kWh to MWh?
A: MWh is more practical for large energy quantities like power plant output or industrial energy use, while kWh is better for household energy measurements.

Q2: How many kWh are in 1 MWh?
A: There are exactly 1,000 kWh in 1 MWh.

Q3: What's the difference between MW and MWh?
A: MW (megawatts) measures power (instantaneous rate of energy), while MWh (megawatt-hours) measures energy (power × time).

Q4: Is this conversion exact?
A: Yes, the conversion is exact by definition, not an approximation.

Q5: When would I need this conversion?
A: Useful for energy professionals, utility companies, renewable energy projects, and anyone comparing energy data at different scales.
