How many megawatts is 1 BTU per hour?

1 BTU/hr equals exactly 0.00000029307107 MW (2.9307107 × 10⁻⁷ MW). To convert large BTU/hr values common in industry, divide by 3,412,142.

What is the formula for BTU/hr to MW?

MW = BTU/hr ÷ 3,412,142. Alternatively, MW = BTU/hr × 0.00000029307107. Both expressions use the exact thermochemical conversion factor.

Why use megawatts instead of BTU/hr for power plants?

Megawatts are the SI standard for large-scale power measurement, making international comparison easier. Power plants are rated in MW while HVAC equipment often uses BTU/hr — this converter bridges the two.

How does BTU/hr differ from BTU?

BTU (British Thermal Unit) measures energy, while BTU/hr measures power — the rate of energy transfer. Megawatt is also a power unit, so the conversion here is power-to-power, not energy-to-power.

Is this converter accurate for engineering calculations?

Yes. The conversion factor used (1 BTU/hr = 2.9307107017 × 10⁻⁷ MW) is the exact thermochemical definition. Results are precise to 10 significant figures.
