To convert thousand BTU per hour to watts, multiply by 293.0710702. That factor is the whole relationship: both units measure power, so the conversion is a proportion with no offset and no substance-specific constant.

One thousand BTU per hour, the unit US boiler and furnace capacity is listed in. The SI unit of power: one joule per second.

Power is not energy. A watt is a rate; a watt-hour is an amount. A 2 kW heater running for three hours uses 6 kWh, and no conversion factor turns one into the other without a time. Horsepower also comes in two sizes: mechanical hp is 745.7 W, metric PS is 735.5 W. Below the calculator there is a step table for the values people look up most, and a second table putting real power figures into watts so the number you get has something to be compared against.

Worked examples

A LED bulb: 0.0307 MBH in watts

At 0.0307 MBH (a led bulb), the same quantity in watts is 0.0307 × 293.071 = 8.99728 W. One thousand BTU per hour is 293.071 watts, so the numbers grow as expected.

A human at rest: 0.341 MBH in watts

A human at rest comes to about 0.341 MBH. Multiplying by the factor: 0.341 × 293.071 = 99.9372 W. Dividing the answer back by 293.071 returns the figure you started with, which is the quickest way to check you have the factor the right way up.

Frequently asked questions

How many watts are in one thousand BTU per hour?

Exactly 293.071070172. Every figure on this page is that one number multiplied by your input, so the only rounding is at the display step.

What is the formula to convert thousand BTU per hour to watts?

watts = thousand BTU per hour × 293.071070172. Reversed, thousand BTU per hour = watts ÷ 293.071070172, which is the same as multiplying by 0.00341214163313.

Which is the bigger unit, the thousand BTU per hour or the watt?

The thousand BTU per hour. One thousand BTU per hour equals 293.071 watts.

What does this quantity actually measure?

Both units measure power. That is why a single factor is enough: there is no temperature offset and no material property involved, unlike conversions that cross between different quantities.

What is a thousand BTU per hour?

One thousand BTU per hour, the unit US boiler and furnace capacity is listed in.

What is a watt?

The SI unit of power: one joule per second.

Why does my answer differ from another converter?

Almost always because the other tool rounded the factor before multiplying. This page keeps full double precision through the calculation and rounds only for display, and it prints the factor it used so you can see where any difference came from.

Is there a quick way to do MBH to W in my head?

Plenty of people do this in their head: multiply by 300 instead of using the exact factor 293.0710702. At 100 that shortcut gives 30,000 watts, off by 692.9 watts or about 2.36%. Fine for a rough estimate, not fine for anything you are cutting to size or dosing.
