Context values
Some unit families need one extra value for a physically accurate result.
Use the converter to see the formula.
Joule and Nanowatt measure different quantities, so no single result applies.

Formula
Joule (J) measures energy, while Nanowatt (nW) measures power. These are different physical quantities, so there is no single multiplication factor that converts one into the other.
J relates to its own energy base unit by a factor of 1. nW relates to its own power base unit by a factor of 1e-09.
Conversion table
| Joule (J) | 1 × energy base unit |
| Nanowatt (nW) | 1e-09 × power base unit |

Frequently asked questions
Can Joule be converted to Nanowatt?
Not directly. Joule measures energy and Nanowatt 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 Joule used for?
The Joule (J) is a unit of energy. The joule is the SI derived unit of energy.
What is Nanowatt used for?
The Nanowatt (nW) is a unit of power. Nanowatt is 1e-9 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 Joule and Nanowatt don't, the tool flags them as not directly compatible rather than returning a meaningless number.
What should I convert Joule to instead?
Use another energy unit, such as one of the related Joule conversions linked below.
What should I convert Nanowatt to instead?
Use another power unit, such as one of the related Nanowatt conversions linked below.

About this conversion
This page compares Joule (J) and Nanowatt (nW) within the engineering converter.
The joule is the SI derived unit of energy. Nanowatt is 1e-9 watt units.
Because Joule measures energy and Nanowatt 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.
