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

Formula
Nanowatt (nW) measures power, while Megajoule (MJ) measures energy. These are different physical quantities, so there is no single multiplication factor that converts one into the other.
nW relates to its own power base unit by a factor of 1e-09. MJ relates to its own energy base unit by a factor of 1000000.
Conversion table
| Nanowatt (nW) | 1e-09 × power base unit |
| Megajoule (MJ) | 1000000 × energy base unit |

Frequently asked questions
Can Nanowatt be converted to Megajoule?
Not directly. Nanowatt measures power and Megajoule 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 Nanowatt used for?
The Nanowatt (nW) is a unit of power. Nanowatt is 1e-9 watt units.
What is Megajoule used for?
The Megajoule (MJ) is a unit of energy. Megajoule is 1000000 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 Nanowatt and Megajoule don't, the tool flags them as not directly compatible rather than returning a meaningless number.
What should I convert Nanowatt to instead?
Use another power unit, such as one of the related Nanowatt conversions linked below.
What should I convert Megajoule to instead?
Use another energy unit, such as one of the related Megajoule conversions linked below.

About this conversion
This page compares Nanowatt (nW) and Megajoule (MJ) within the engineering converter.
Nanowatt is 1e-9 watt units. Megajoule is 1000000 joule units.
Because Nanowatt measures power and Megajoule 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.
