Frequently asked questions
What is the source unit in this conversion?
The source unit is the milliwatt (mW). A milliwatt is 0.001 watt units.
What is the destination unit in this conversion?
The destination unit is the btu per hour (BTU/h). BTU per hour measures power as British thermal units transferred each hour, common for heating and cooling equipment.
How do I convert milliwatts to btu per hour?
Multiply the milliwatt value by 0.003412141633 to get btu per hour. For example, 1000 mW × 0.003412141633 = 3.41214 BTU/h.
Is the milliwatts to btu per hour conversion exact?
Yes. Both units are defined by fixed numeric relationships to the watt, so the conversion factor used here, 0.003412141633, is exact.
Where is this conversion commonly used?
It is used when comparing power ratings expressed in milliwatts against equipment, engines, or specifications rated in btu per hour.
Can I convert btu per hour back to milliwatts?
Yes. Multiply the btu per hour value by 293.0710702 to get milliwatt.

About this conversion
This page converts milliwatts (mW) into btu per hour (BTU/h), two units used to describe power, the rate at which energy is transferred or work is done.
A milliwatt is 0.001 watt units.
BTU per hour measures power as British thermal units transferred each hour, common for heating and cooling equipment.
The formula is BTU/h = mW × 0.003412141633, derived from each unit's fixed relationship to the watt, the SI unit of power.
Because both units are defined by exact numeric relationships to the watt, this conversion is exact rather than approximate.
