How many BTU/hr is 1 megawatt?

1 megawatt equals 3,412,142 BTU per hour. The factor comes from 1 Wh = 3.41214 BTU, so 1 MW (= 1,000,000 W) produces 3,412,142 BTU/hr of power flow.

What is the difference between a megawatt and a BTU/hr?

Both measure the rate of energy transfer (power), but in different unit systems. Megawatt is the SI metric unit (1 MW = 1,000,000 W), while BTU/hr is the traditional US imperial unit used heavily in HVAC and utility engineering.

How do I convert BTU/hr back to megawatts?

Divide BTU/hr by 3,412,142 to get megawatts. For example, 10,000,000 BTU/hr ÷ 3,412,142 ≈ 2.931 MW.

Why do power engineers use both MW and BTU/hr?

Electrical output is typically reported in megawatts (MW), while thermal output or heat input from fuel combustion is often given in BTU/hr in North American engineering practice. Conversion is needed when comparing or balancing both sides of an energy system.

Is this converter accurate enough for engineering calculations?

Yes. The factor 3,412,142 BTU/hr per MW is exact within six significant figures, matching the thermodynamic definition. For precision work, the full factor is 3,412,141.633 BTU/hr per MW.
