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

Formula
PSI (psi) measures pressure and mechanical stress, while Dyne (dyn) measures force. These are different physical quantities, so there is no single multiplication factor that converts one into the other.
psi relates to its own pressure and mechanical stress base unit by a factor of 6894.76. dyn relates to its own force base unit by a factor of 1e-05.

Frequently asked questions
Can PSI be converted to Dyne?
Not directly. PSI measures pressure and mechanical stress and Dyne measures force. Converting between different physical quantities needs an extra physical relationship (such as area, distance, or time), not just a unit ratio.
What is PSI used for?
The PSI (psi) is a unit of pressure and mechanical stress. Pounds per square inch.
What is Dyne used for?
The Dyne (dyn) is a unit of force. A dyne is a CGS force unit.
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 PSI and Dyne don't, the tool flags them as not directly compatible rather than returning a meaningless number.
What should I convert PSI to instead?
Use another pressure and mechanical stress unit, such as one of the related PSI conversions linked below.
What should I convert Dyne to instead?
Use another force unit, such as one of the related Dyne conversions linked below.

About this conversion
This page compares PSI (psi) and Dyne (dyn) within the engineering converter.
Pounds per square inch. A dyne is a CGS force unit.
Because PSI measures pressure and mechanical stress and Dyne measures force, 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.
