Convert energy units — joules, kilowatt-hours, calories, BTU, electron volts and more.
| Unit | Name | Value |
|---|---|---|
| 0.001 MWh | 1 kWh | |
| 0.01 MWh | 10 kWh | |
| 0.1 MWh | 100 kWh | |
| 1 MWh | 1000 kWh | |
| 5 MWh | 5000 kWh | |
| 10 MWh | 10000 kWh | |
| 50 MWh | 50000 kWh | |

Formula: Kilowatt-Hour = Megawatt-Hour × 1000
Multiply any megawatt-hour value by 1000 to get kilowatt-hour.
Reverse: Megawatt-Hour = Kilowatt-Hour × 0.001
Common megawatt-hour values — factor: 1 MWh = 1000 kWh

MWh × 1,000 = kWh. Exact.
One megawatt-hour = exactly 1,000 kilowatt-hours.
kWh ÷ 1,000 = MWh.
Reports generation output and fuel consumption in MWh.
Balances supply and demand in real time using MWh dispatch orders.
Buys and sells electricity in MWh on wholesale power markets.
Models solar and wind farm annual output in MWh for investors.
Monitors and reports monthly energy consumption in MWh.
Calculates Scope 2 emissions from electricity use in MWh.
The megawatt-hour (MWh) equals 1,000 kWh or 3.6 × 10⁹ joules. It is the standard unit for utility-scale electricity generation, large industrial consumers, and grid-level energy storage.
Power plants, wind farms, and solar installations are rated and billed in MWh. A 2 MW wind turbine generates about 6 MWh per day on average. Large data centers consume thousands of MWh per month.
Interesting fact: The Hoover Dam generates about 4,000 MWh per hour. A single nuclear power plant produces about 8,000 MWh per hour. World electricity consumption is approximately 25,000 TWh (25 billion MWh) per year.
The kilowatt-hour (kWh) is the commercial unit of electrical energy, equal to the energy consumed by a 1,000-watt appliance in one hour (3,600,000 joules). It became standard with the growth of the electrical grid in the late 19th century.
Electricity bills worldwide are denominated in kWh. A typical household uses 300–1,000 kWh per month. An electric car uses about 15–25 kWh per 100 km. Solar panels generate 250–400 kWh per year per panel.
Interesting fact: The average price of electricity in the US is about $0.12 per kWh. One kWh can run a 100W light bulb for 10 hours, charge a smartphone about 100 times, or power a laptop for 2-3 days.
Converting megawatt-hour to kilowatt-hour is common across energy, nutrition, engineering, and science. Different sectors use different energy units — joules in physics, kcal in nutrition, kWh in electricity, and BTU in HVAC — making accurate conversion essential for cross-disciplinary work and international comparisons.
Quick reference: 5 MWh = 5000 kWh and 10 MWh = 10,000 kWh. Reverse: 1 kWh = 0.001 MWh. Exact factor: 1 MWh = 1000 kWh.
All conversions use IEEE 754 double-precision arithmetic, accurate to at least 8 significant figures.
