The British Thermal Unit (BTU) is the traditional Imperial energy unit, defined as the heat required to raise 1 pound of water by 1°F. It equals 1,055.06 joules and has been used since the 19th century in heating, air conditioning, and gas billing.
BTU remains dominant in US HVAC: air conditioners and heaters are rated in BTU/hour. Natural gas is priced in therms (100,000 BTU) in the US. Furnaces are rated in BTU/hour output.
Interesting fact: A typical US home furnace is rated at 80,000–120,000 BTU/hour. One BTU is roughly the energy released by burning one kitchen match. The US natural gas pipeline system delivers about 25 quadrillion BTU (quads) per year.
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.
Converting btu to megawatt-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 BTU = 1.4654e-6 MWh and 10 BTU = 2.9307e-6 MWh. Reverse: 1 MWh = 3.412e+06 BTU. Exact factor: 1 BTU = 2.9307e-7 MWh.
All conversions use IEEE 754 double-precision arithmetic, accurate to at least 8 significant figures.
