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

Formula
Exajoule (EJ) 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.
EJ relates to its own energy base unit by a factor of 1e+18. nW relates to its own power base unit by a factor of 1e-09.
Conversion table
| Exajoule (EJ) | 1e+18 × energy base unit |

Frequently asked questions
Can Exajoule be converted to Nanowatt?
Not directly. Exajoule 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 Exajoule used for?
The Exajoule (EJ) is a unit of energy. Exajoule is 1000000000000000000 joule units.
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 Exajoule and Nanowatt don't, the tool flags them as not directly compatible rather than returning a meaningless number.
What should I convert Exajoule to instead?
Use another energy unit, such as one of the related Exajoule 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 Exajoule (EJ) and Nanowatt (nW) within the engineering converter.
Exajoule is 1000000000000000000 joule units. Nanowatt is 1e-9 watt units.
Because Exajoule 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.
