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

Formula
Terawatt (TW) measures power, while Millijoule (mJ) measures energy. These are different physical quantities, so there is no single multiplication factor that converts one into the other.
TW relates to its own power base unit by a factor of 1000000000000. mJ relates to its own energy base unit by a factor of 0.001.

Frequently asked questions
Can Terawatt be converted to Millijoule?
Not directly. Terawatt measures power and Millijoule 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 Terawatt used for?
The Terawatt (TW) is a unit of power. Terawatt is 1000000000000 watt units.
What is Millijoule used for?
The Millijoule (mJ) is a unit of energy. Millijoule is 0.001 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 Terawatt and Millijoule don't, the tool flags them as not directly compatible rather than returning a meaningless number.
What should I convert Terawatt to instead?
Use another power unit, such as one of the related Terawatt conversions linked below.
What should I convert Millijoule to instead?
Use another energy unit, such as one of the related Millijoule conversions linked below.

About this conversion
This page compares Terawatt (TW) and Millijoule (mJ) within the engineering converter.
Terawatt is 1000000000000 watt units. Millijoule is 0.001 joule units.
Because Terawatt measures power and Millijoule 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.
