Formula
Kilocalorie (kcal) measures energy, while Microwatt (uW) measures power. These are different physical quantities, so there is no single multiplication factor that converts one into the other.
kcal relates to its own energy base unit by a factor of 4184. uW relates to its own power base unit by a factor of 1e-06.
Conversion table
| Kilocalorie (kcal) | 4184 × energy base unit |

Frequently asked questions
Can Kilocalorie be converted to Microwatt?
Not directly. Kilocalorie measures energy and Microwatt measures power. Converting between different physical quantities needs an extra physical relationship (such as area, distance, or time), not just a unit ratio.
What is Kilocalorie used for?
The Kilocalorie (kcal) is a unit of energy. A kilocalorie is 1,000 calories.
What is Microwatt used for?
The Microwatt (uW) is a unit of power. Microwatt is 0.000001 watt units.
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 Kilocalorie and Microwatt don't, the tool flags them as not directly compatible rather than returning a meaningless number.
What should I convert Kilocalorie to instead?
Use another energy unit, such as one of the related Kilocalorie conversions linked below.
What should I convert Microwatt to instead?
Use another power unit, such as one of the related Microwatt conversions linked below.

About this conversion
This page compares Kilocalorie (kcal) and Microwatt (uW) within the engineering converter.
A kilocalorie is 1,000 calories. Microwatt is 0.000001 watt units.
Because Kilocalorie measures energy and Microwatt measures power, 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.
