How to Convert BTU per Hour to Megawatt Manually
Step by StepConverting BTU per hour to megawatts is straightforward: multiply by the conversion factor. Follow these three steps to do it by hand or in your head.
- 1Take your value in BTU per hourStart with the number of BTU per hour (BTU/h) you want to convert.
- 2Multiply by 2.931e-7The conversion factor from BTU/h to MW is 2.931e-7. Multiply your value by this number.
- 3Read the result in megawattsThe result is your value in megawatts (MW).
Formula
Multiply the value in BTU per hour by 2.931e-7. For the reverse direction, multiply by 3,412,141.6.
MW = BTU/h × 2.931e-7BTU/h = MW × 3,412,141.6Tips
Use these in everyday conversions- 1 BTU/h = 0.293 W; 3412 BTU/h = 1 kW.
- 12,000 BTU/h = 1 ton of refrigeration.
- Tons of AC rating: divide BTU/h by 12,000.
Common Mistakes
Avoid these- Confusing BTU (energy) with BTU/h (power) — same abbreviation in ads.
- Mixing tons of AC and tons of weight — different concepts.
- Using BTU/h for non-HVAC contexts.
About BTU per Hour and Megawatt
What is the BTU per Hour?
BTU per hour (BTU/h or BTUh) is the standard rating for American heating, air-conditioning, and refrigeration system capacity. A window air conditioner is typically 5,000–12,000 BTU/h, central residential AC ranges 24,000–60,000 BTU/h, and commercial chillers reach 100,000–1,000,000+ BTU/h. The unit's persistence in HVAC reflects American engineering tradition: it directly links cooling/heating capacity to the BTU energy unit familiar in gas-fired equipment. 12,000 BTU/h equals 'one ton of refrigeration' (a unit derived from the heat needed to melt 1 ton of ice in 24 hours), so AC sizes are sometimes given in 'tons' (a 3-ton AC = 36,000 BTU/h). BTU/h relates to the watt (1 W ≈ 3.412 BTU/h), the kilowatt (1 kW ≈ 3,412 BTU/h), and the ton of refrigeration (12,000 BTU/h = 1 ton). Outside the US, kW is dominant for HVAC capacity.

- US furnace and boiler ratings
- Some industrial heat-exchanger specs
Small window AC: 5000 BTU/h. Central AC: 24,000 BTU/h. Home furnace: 80,000 BTU/h.
What is the Megawatt?
The megawatt equals 1,000,000 watts (or 1,000 kW) and rates power plants, large industrial facilities, and grid-scale renewable installations worldwide. A typical natural-gas turbine generates 50–500 MW, a nuclear reactor produces 800–1,600 MW, and the largest hydroelectric plant (Three Gorges Dam in China) has 22,500 MW capacity. Wind turbines are rated 1.5–15 MW each (modern offshore turbines reach 14 MW). Solar farms range from 50 MW (small) to 1,500+ MW (large utility-scale projects). Electric grid demand for entire countries is measured in gigawatts (1 GW = 1,000 MW): the United States peaks at about 750 GW. The megawatt relates to the kilowatt (1,000 kW = 1 MW), the gigawatt (1,000 MW = 1 GW), and the megawatt-hour (when multiplied by time). Electricity wholesale markets bid in MW capacity and MWh energy.
- Power-station electrical output
- Wind and solar farm capacity
- Large industrial electricity consumption
Large wind turbine: 5–15 MW. Nuclear reactor: 1000 MW. London's peak demand: ~6000 MW.
