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

Formula
Rontowatt (rW) measures power, while Bar (bar) measures pressure and mechanical stress. These are different physical quantities, so there is no single multiplication factor that converts one into the other.
rW relates to its own power base unit by a factor of 0. bar relates to its own pressure and mechanical stress base unit by a factor of 100000.

Frequently asked questions
Can Rontowatt be converted to Bar?
Not directly. Rontowatt measures power and Bar measures pressure and mechanical stress. Converting between different physical quantities needs an extra physical relationship (such as area, distance, or time), not just a unit ratio.
What is Rontowatt used for?
The Rontowatt (rW) is a unit of power. Rontowatt is 1e-27 watt units.
What is Bar used for?
The Bar (bar) is a unit of pressure and mechanical stress. A bar is exactly 100,000 pascals.
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 Rontowatt and Bar don't, the tool flags them as not directly compatible rather than returning a meaningless number.
What should I convert Rontowatt to instead?
Use another power unit, such as one of the related Rontowatt conversions linked below.
What should I convert Bar to instead?
Use another pressure and mechanical stress unit, such as one of the related Bar conversions linked below.

About this conversion
This page compares Rontowatt (rW) and Bar (bar) within the engineering converter.
Rontowatt is 1e-27 watt units. A bar is exactly 100,000 pascals.
Because Rontowatt measures power and Bar measures pressure and mechanical stress, 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.
