Enter a Megawatt-hour (MWh) value and get the Kilowatt-hour (kWh) result. The conversion factor is 1 MWh = 1,000 kWh.
A unit of energy equal to 1,000 kilowatt-hours
A Megawatt-hour (MWh) is a unit of electrical energy equal to 1,000 Kilowatt-hours (kWh) or 1,000,000 Watt-hours (Wh). One MWh represents the amount of energy produced or consumed when a 1 Megawatt (MW) load operates for 1 hour.
Power plants, solar farms, wind farms, and hydroelectric dams report their electricity generation in MWh. Utility companies trade electricity on wholesale markets in MWh. Grid storage systems rate their capacity in MWh. A typical 5 MW wind turbine operating at 30% capacity factor generates about 13,140 MWh (13,140,000 kWh) per year.
1 MWh powers approximately 330 US homes for one hour, or one average US home for about 34 days, based on the national average consumption of 886 kWh (0.886 MWh) per month.

The standard unit on residential electricity bills
A Kilowatt-hour (kWh) is a unit of electrical energy equal to 1,000 Watt-hours (Wh). One kWh represents the energy consumed when a 1,000-watt (1 kW) appliance runs for 1 hour. Utility companies use kWh as the standard billing unit on residential electricity bills worldwide.
Smart meters installed by utility companies record electricity consumption in kWh. The meter reading at the end of a billing period minus the reading at the start gives the total kWh consumed. The utility multiplies this figure by the rate per kWh — typically between $0.10 and $0.35 in the United States — to calculate the electricity bill amount.
One kWh equals 0.001 MWh. An average US household consumes about 886 kWh (0.886 MWh) per month, or approximately 10,632 kWh (10.632 MWh) per year.

Answers to the most common questions about MWh and kWh energy unit conversions
There are exactly 1,000 Kilowatt-hours (kWh) in one Megawatt-hour (MWh). The prefix "Mega" represents 1,000,000 watts and the prefix "Kilo" represents 1,000 watts in the International System of Units (SI).
A Megawatt-hour (MWh) measures electrical energy — the total amount of electricity generated or consumed over time. Power plants report output in MWh. Utility companies use MWh for wholesale electricity trading.
A Kilowatt-hour (kWh) represents the amount of electrical energy a household consumes during a billing period. Smart meters record consumption in kWh.
MWh is a unit of energy, not power. Power is measured in watts (W), kilowatts (kW), or megawatts (MW). Energy is measured in watt-hours (Wh), kilowatt-hours (kWh), or megawatt-hours (MWh).
Large power stations use MWh because their output is too large to express in kWh. Writing 12,000 MWh is clearer than writing 12,000,000 kWh.
Multiply the MWh value by 1,000 to get kWh. The MWh to kWh formula is: kWh = MWh × 1,000. For example, 3.5 MWh × 1,000 = 3,500 kWh.
2 MWh = 2,000 kWh. Apply the formula: 2 MWh × 1,000 = 2,000 kWh. This amount equals roughly 2 months of electricity consumption for an average household.
Homes use kWh because monthly residential consumption falls within the hundreds or low thousands of kilowatt-hours.
Yes, multiply any decimal MWh value by 1,000 to get kWh. Examples: 0.01 MWh = 10 kWh, 0.15 MWh = 150 kWh, and 2.4 MWh = 2,400 kWh.
Yes, divide the kWh value by 1,000 to get MWh. The kWh to MWh formula is: MWh = kWh ÷ 1,000. Examples: 2,000 kWh ÷ 1,000 = 2 MWh.
