pound per square inch [psi] to hectopascal [hPa] Converter

Quick Reference

1 pound per square inch (psi) = 68.9476 hectopascal (hPa)

1 hectopascal (hPa) = 0.01450376808 pound per square inch (psi)

How to Convert pound per square inch to hectopascal

1 psi = 68.9476 hPa
1 hPa = 0.01450376808 psi

To convert pound per square inch to hectopascal, multiply the value by 68.9476. To convert hectopascal back to pound per square inch, divide by 68.9476.

Example: convert 10 psi to hPa:
10 psi = 10 x 68.9476 = 689.476 hPa

↔ Convert hectopascal to pound per square inch

pound per square inch

Definition: Pound per square inch (symbol: psi or lbf/in²) is a unit of pressure in the imperial and US customary systems. It is defined as the pressure resulting from a force of one pound-force applied to an area of one square inch.

History/origin: The pound per square inch is rooted in the English system of units. Its widespread use grew with the development of steam engines and other technologies requiring pressure measurements.

Current use: psi is commonly used in the United States for measuring tire pressure, hydraulic pressure, steam pressure, and the pressure of compressed gases. It's prevalent in automotive, manufacturing, and various engineering applications.

hectopascal

Definition: The hectopascal (symbol: hPa) is a multiple of the pascal, which is the SI unit of pressure. One hPa is equal to 100 pascals.

History/origin: The hectopascal was introduced as a replacement for the millibar (mbar) in meteorology. The change was intended to promote the use of SI units.

Current use: Hectopascals are primarily used in meteorology for measuring atmospheric pressure. 1 hPa is equivalent to 1 mbar, which was previously the standard unit for atmospheric pressure.
