Formula
Milliwatt (mW) measures power, while Foot-pound (ft-lb) measures energy. These are different physical quantities, so there is no single multiplication factor that converts one into the other.
mW relates to its own power base unit by a factor of 0.001. ft-lb relates to its own energy base unit by a factor of 1.35582.

Frequently asked questions
Can Milliwatt be converted to Foot-pound?
Not directly. Milliwatt measures power and Foot-pound measures energy. Converting between different physical quantities needs an extra physical relationship (such as area, distance, or time), not just a unit ratio.
What is Milliwatt used for?
The Milliwatt (mW) is a unit of power. Milliwatt is 0.001 watt units.
What is Foot-pound used for?
The Foot-pound (ft-lb) is a unit of energy. Work from one pound-force over one foot.
Why does the converter show an incompatible units message?
The Universal Converter only calculates a numeric result when both units share the same physical dimension. Since Milliwatt and Foot-pound don't, the tool flags them as not directly compatible rather than returning a meaningless number.
What should I convert Milliwatt to instead?
Use another power unit, such as one of the related Milliwatt conversions linked below.
What should I convert Foot-pound to instead?
Use another energy unit, such as one of the related Foot-pound conversions linked below.

About this conversion
This page compares Milliwatt (mW) and Foot-pound (ft-lb) within the engineering converter.
Milliwatt is 0.001 watt units. Work from one pound-force over one foot.
Because Milliwatt measures power and Foot-pound measures energy, the two units are not directly convertible: there is no fixed ratio that turns one into the other without additional information.
The calculator above will report that these units are not compatible. For a working result, choose two units from the same measurement family — see the related conversions below.
