120 Psi to Kpa – Full Calculation Guide

120 psi equals approximately 820.7 kpa.

The conversion from psi to kpa involves multiplying the psi value by 6.89476, because 1 psi equals 6.89476 kilopascals. This means that to find the kpa, you simply take the psi measurement and multiply it by this factor, giving you a precise pressure value in kilopascals.

Conversion Result and Explanation

When converting 120 psi, the calculation is 120 multiplied by 6.89476, resulting in 827.3712 kpa, which rounds to about 820.7 kpa. This conversion helps to switch between different pressure measurement systems, especially in engineering or scientific contexts where kpa is used more.

Conversion Formula

The formula to convert psi to kpa is: kpa = psi × 6.89476. This works because 1 psi equals 6.89476 kilopascals, a fixed conversion factor based on the definitions of these pressure units. By multiplying the psi value by this number, you get the equivalent pressure in kpa.

For example, if you have 50 psi, the math is 50 × 6.89476 = 344.738 kpa. Each psi value is scaled proportionally to the kilopascal unit, making the conversion straightforward and precise.

Conversion Definitions

psi

Psi is a pressure unit indicating pounds per square inch, measuring force applied over an area. It is mainly used in the United States for tire pressures, plumbing, and some engineering contexts, representing the amount of force exerted per inch square.

kpa

Kilopascal (kpa) is a metric pressure unit equal to 1,000 pascals, where one pascal is one newton per square meter. It is utilized globally in scientific, medical, and technical fields to measure pressure, replacing psi in many countries for standardization.
