About Converting BTU per hour to Microwatts
BTU per hour and Microwatt both measure a quantity used in structural or mechanical engineering — commonly stress, pressure, force, torque, power, or energy — where converting between the unit conventions used in different regions, industries, or equipment specifications is a routine part of design work. Specifically: Power rate using BTU per hour, and microwatt is 0.000001 watt units.
Formula
microwatts = btu per hour × 293071.070172
This factor comes from each unit's defined relationship to the category's base unit: 1 btu per hour equals 0.293071070172 base units, and 1 microwatt equals 0.000001 base units, so dividing one by the other gives the direct btu per hour-to-microwatt factor of 293071.070172.
Simple example
1 BTU/h × 293071.0702 = 293,071.0702 uW
1 btu per hour = 293,071.0702 microwatts.
Real-world example
100 BTU/h × 293071.0702 = 29,307,107.02 uW
100 btu per hour = 29,307,107.02 microwatts.

Frequently asked questions
How many microwatts are in 1 btu per hour?
1 btu per hour equals 293,071.0702 microwatts, using the exact defined conversion factor rather than an estimate.
How do I convert btu per hour to microwatt?
Multiply the btu per hour value by 293071.0702. The converter above does this instantly to whatever precision you set.
How do I convert microwatt back to btu per hour?
Use the reverse factor: 1 microwatt equals 0.0000034121 btu per hour. You can also use the swap control in the converter above to flip the direction instantly.
What is a btu per hour?
BTU per hour (BTU/h) is a unit of engineering.
What is a microwatt?
Microwatt (uW) is a unit of engineering.
Is the btu per hour to microwatt conversion exact?
Yes. Both btu per hour and microwatt are defined by fixed standards rather than physical artifacts, so the factor of 293071.0702 used above is exact to as many digits as you choose to display.
Why do engineering unit conventions vary so much by region and industry?
Pressure, force, and stress can be expressed in metric (pascal, newton), US customary (psi, pound-force), or older and industry-specific units (atmosphere, torr, kip) depending on the country, industry, and even the equipment manufacturer, which is why engineers routinely need to convert between them when working across specs from different sources.
