Frequently asked questions
What is the source unit in this conversion?
The source unit is the Decapascal (daPa). Decapascal is 10 pascal units.
What is the destination unit in this conversion?
The destination unit is the PSI (psi). Pounds per square inch.
How do I convert Decapascal to PSI?
Multiply the Decapascal value by 0.00145038. For example, 10 daPa × 0.00145038 = 0.0145038 psi.
Is the Decapascal to PSI conversion exact?
Yes. Both units belong to the same engineering measurement family (pressure and mechanical stress), so the ratio between them is a fixed, defined value rather than a measured approximation.
Where is this conversion commonly used?
It's used whenever a value expressed in Decapascal needs to be compared with, or reported in, PSI, such as in engineering, scientific, or industrial calculations.
Can I convert PSI back to Decapascal?
Yes. Multiply the PSI value by 689.476 to get Decapascal.

About this conversion
This page converts Decapascal (daPa) to PSI (psi) within the engineering converter.
Decapascal is 10 pascal units. Pounds per square inch.
The formula is psi = daPa × 0.00145038, based on each unit's fixed relationship to the pressure and mechanical stress base unit.
The conversion is exact, since it relies on a fixed numerical ratio between the two units rather than a measured or approximate value.
