Formula
Picowatt (pW) measures power, while Microjoule (uJ) measures energy. These are different physical quantities, so there is no single multiplication factor that converts one into the other.
pW relates to its own power base unit by a factor of 0. uJ relates to its own energy base unit by a factor of 1e-06.
Conversion table
| Picowatt (pW) | 0 × power base unit |
| Microjoule (uJ) | 1e-06 × energy base unit |

Frequently asked questions
Can Picowatt be converted to Microjoule?
Not directly. Picowatt measures power and Microjoule 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 Picowatt used for?
The Picowatt (pW) is a unit of power. Picowatt is 1e-12 watt units.
What is Microjoule used for?
The Microjoule (uJ) is a unit of energy. Microjoule is 0.000001 joule 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 Picowatt and Microjoule don't, the tool flags them as not directly compatible rather than returning a meaningless number.
What should I convert Picowatt to instead?
Use another power unit, such as one of the related Picowatt conversions linked below.
What should I convert Microjoule to instead?
Use another energy unit, such as one of the related Microjoule conversions linked below.

About this conversion
This page compares Picowatt (pW) and Microjoule (uJ) within the engineering converter.
Picowatt is 1e-12 watt units. Microjoule is 0.000001 joule units.
Because Picowatt measures power and Microjoule 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.
