About Converting Microwatts to BTU per hour
Microwatt and BTU per hour 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: Microwatt is 0.000001 watt units, and power rate using BTU per hour.
Formula
btu per hour = microwatts × 0.00000341214163313
This factor comes from each unit's defined relationship to the category's base unit: 1 microwatt equals 0.000001 base units, and 1 btu per hour equals 0.293071070172 base units, so dividing one by the other gives the direct microwatt-to-btu per hour factor of 0.00000341214163313.
Simple example
1 uW × 0.000003412141633 = 0.0000034121 BTU/h
1 microwatt = 0.0000034121 btu per hour.
Real-world example
100 uW × 0.000003412141633 = 0.0003412142 BTU/h
100 microwatts = 0.0003412142 btu per hour.

Frequently asked questions
How many btu per hour are in 1 microwatt?
1 microwatt equals 0.0000034121 btu per hour, using the exact defined conversion factor rather than an estimate.
How do I convert microwatt to btu per hour?
Multiply the microwatt value by 0.000003412141633. The converter above does this instantly to whatever precision you set.
How do I convert btu per hour back to microwatt?
Use the reverse factor: 1 btu per hour equals 293,071.0702 microwatts. You can also use the swap control in the converter above to flip the direction instantly.
What is a microwatt?
Microwatt (uW) is a unit of engineering.
What is a btu per hour?
BTU per hour (BTU/h) is a unit of engineering.
Is the microwatt to btu per hour conversion exact?
Yes. Both microwatt and btu per hour are defined by fixed standards rather than physical artifacts, so the factor of 0.000003412141633 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.
