Formula
Yoctowatt (yW) 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.
yW relates to its own power base unit by a factor of 0. MJ relates to its own energy base unit by a factor of 1000000.

Frequently asked questions
Can Yoctowatt be converted to Megajoule?
Not directly. Yoctowatt 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 Yoctowatt used for?
The Yoctowatt (yW) is a unit of power. Yoctowatt is 1e-24 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 Yoctowatt and Megajoule don't, the tool flags them as not directly compatible rather than returning a meaningless number.
What should I convert Yoctowatt to instead?
Use another power unit, such as one of the related Yoctowatt 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 Yoctowatt (yW) and Megajoule (MJ) within the engineering converter.
Yoctowatt is 1e-24 watt units. Megajoule is 1000000 joule units.
Because Yoctowatt 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.
