Convert BTU per Hour to Megawatts

About converting BTU per Hour to Megawatts

BTU per Hour (BTU/h) and Megawatts (MW) are both units of power, so converting between them is a single multiplication: multiply your BTU per Hour figure by 0.0000002931. Ten BTU per Hour comes to 0.000002931 Megawatts, and a hundred works out at 0.00002931 Megawatts.

Rule of thumb: going from BTU per Hour to Megawatts divides, so the figure always shrinks — it takes about 3,412,141.64 BTU per Hour to make a single Megawatt. If your answer came out bigger, you have the conversion the wrong way round.

What is a BTU per Hour?

BTU per hour is the unit American heating and cooling equipment is sized in: furnaces, boilers, air conditioners and heat pumps all carry a BTU/h rating. It is a rate of heat flow — genuinely a power, in the same family as the watt — but the "per hour" is dropped so routinely in advertising that a "12,000 BTU air conditioner" reads as normal, which quietly confuses a quantity of energy with a rate of delivering it. It also inherits the BTU’s vagueness: several BTU definitions exist and differ by a fraction of a percent, so any conversion here rests on one chosen convention.

What is a Megawatt?

A megawatt is a million watts, and it is the unit the electricity system is discussed in. Power stations, wind farms, solar arrays, interconnectors and national demand are all quoted in megawatts, and data centres have joined them — a modern campus is described by the megawatts it draws. The number is a capacity, a maximum rate, not a quantity delivered, which is why a wind farm "rated" at 100 MW does not produce anything close to that around the clock; what it actually generated over a year is a figure in megawatt-hours. Confusing the two is the most common error in energy reporting.

To put both in perspective: a window air conditioner is usually 5,000 to 12,000 BTU per hour, while a large wind turbine is rated at a few megawatts.
