| 1000 MMBtu | 293.0711 MWh | 293071 kWh | Industrial facility |
How to Convert MMBtu to MWh
Multiply by 0.29307107:
Example: 10 MMBtu (average US home monthly gas)
= 10 Γ 0.29307107 = 2.9307 MWh
Example: 1 MMBtu
= 1 Γ 0.29307107 = 0.2931 MWh = 293.07 kWh
Example: 100 MMBtu (commercial building)
= 100 Γ 0.29307107 = 29.307 MWh
Key relationship: 1 MMBtu = 10 therms = 293.07 kWh = 0.2931 MWh. These units appear on US gas and electric bills.

Understanding US Natural Gas Pricing
In the US, natural gas is priced per MMBtu at the wholesale level (Henry Hub benchmark) and per therm or CCF on residential utility bills:
| Level | Unit | Typical Price | Who Uses It |
|---|---|---|---|
| Wholesale (Henry Hub) | $/MMBtu | $2β$6/MMBtu | Traders, utilities, power plants |
| Residential utility | $/therm | $0.50β$1.50/therm | Homeowners (gas bills) |
| Residential utility | $/CCF | $0.50β$1.50/CCF | Homeowners (some utilities) |
| Electricity equivalent | $/kWh | $0.10β$0.20/kWh | Electric bills for comparison |
| Electricity wholesale | $/MWh | $30β$80/MWh | Power grid operators, ISOs |

What Is a Million BTU (MMBtu)?
MMBtu stands for one million British Thermal Units. The "MM" comes from the Roman numeral for 1,000 Γ 1,000. It's the standard unit for pricing natural gas in the US β Henry Hub prices, EIA reports, and commercial energy contracts all use $/MMBtu. One MMBtu equals 10 therms or approximately 1,000 cubic feet (MCF) of natural gas.
What Is a Megawatt Hour (MWh)?
MWh (megawatt hour) equals 1,000 kilowatt hours. It's the standard unit for wholesale electricity trading in the US. Regional grid operators (ERCOT, PJM, CAISO, MISO, etc.) price electricity in $/MWh. One MWh can power about 30 average US homes for one hour, or one home for about 30 hours.
