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 0.00145. For example, 10 daPa × 0.00145 = 0.014504 psi.
Is the decapascal to psi conversion exact?
Yes. Both units are defined as fixed multiples of the pascal, the SI-derived unit of pressure, so the conversion factor follows directly from those exact definitions 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 specifications, weather readings, tire pressure, or industrial and scientific work.
Can I convert psi back to decapascal?
Yes. Multiply the psi value by 689.475729 to get decapascal.

About this conversion
This page converts decapascal (daPa) to psi (psi) within the pressure converter.
Decapascal is 10 pascal units. Pounds per square inch.
The formula is psi = decapascal × 0.00145, based on each unit's fixed relationship to the pascal, the pressure converter's base unit.
The conversion is exact, since both units are tied to the pascal by a fixed numerical ratio rather than a measured or approximate value.
