What does milliwatt measure?

Milliwatt (mW) measures power equal to one thousandth of a watt, indicating the rate of energy transfer commonly used for low power levels in electrical and optical devices.

Why convert milliwatt to Btu (IT)/hour?

Converting milliwatt to Btu (IT)/hour helps interpret electrical power levels in terms of heat transfer rates, useful in thermal system analysis and HVAC applications.

Are these conversions suitable for varying load conditions?

No, this conversion assumes steady-state power and does not account for transient thermal or varying load effects.
