3 kilopascal (kpa) equals approximately 0.4348 psi.
To convert 3 kpa to psi, multiply the pressure in kilopascals by 0.1450377, since 1 kpa equals 0.1450377 psi. Using this factor, the calculation gives 3 × 0.1450377 = 0.4351131 psi, which rounded to four decimal places is 0.4348 psi. This conversion helps translate metric pressure to imperial units.
Conversion Result
The pressure of 3 kpa converts to about 0.4348 psi. This small value shows that kilopascals and pounds per square inch are different ways of measuring the same physical quantity, pressure, but expressed in different units.

Conversion Formula
The conversion from kpa to psi relies on the formula: psi = kpa × 0.1450377. This works because 1 kpa equals 0.1450377 psi, derived from the relationship between the metric and imperial pressure units. For example, converting 3 kpa: 3 × 0.1450377 = 0.4351131 psi, close to our initial calculation.
Conversion Example
- Convert 10 kpa to psi:
- Multiply 10 by 0.1450377.
- 10 × 0.1450377 = 1.450377 psi.
- Convert 5 kpa to psi:
- Multiply 5 by 0.1450377.
- 5 × 0.1450377 = 0.7251885 psi.
- Convert 20 kpa to psi:
- Multiply 20 by 0.1450377.
- 20 × 0.1450377 = 2.900754 psi.
- Convert 0 kpa to psi:
- Any value multiplied by zero results in zero.
- 0 × 0.1450377 = 0 psi.

Conversion Definitions
Kpa
Kilopascal (kpa) is a metric unit measuring pressure, where 1 kpa equals 1000 pascals, representing force per unit area. It is used in various fields like meteorology and engineering to quantify pressure levels.
Psi
Pounds per square inch (psi) is an imperial pressure unit measuring force applied over an area of one square inch, widely used in the United States for tire pressure, plumbing, and other pressure-related measurements.
