27 kpa is approximately 3.92 psi
When converting 27 kilopascals (kpa) to pounds per square inch (psi), the result is about 3.92 psi. This conversion helps relate pressure measurements between the metric and imperial systems, allowing for easier understanding in contexts like tire pressures or plumbing systems.
To convert from kpa to psi, you multiply the pressure in kilopascals by the conversion factor 0.145038. This factor comes from the relationship between the SI unit of pressure (pascal) and the imperial unit (psi). Since 1 kpa equals 1000 pascals, and 1 psi equals 6894.76 pascals, the ratio simplifies to approximately 0.145038. So, 27 kpa times 0.145038 gives roughly 3.92 psi.

Conversion Formula
The conversion formula from kilopascals to psi is: psi = kpa × 0.145038. This works because 1 kpa equals 1000 pascals, and since 1 psi equals 6894.76 pascals, dividing 1000 by 6894.76 gives the factor 0.145038. For example, converting 50 kpa: 50 × 0.145038 = 7.2519 psi.
Conversion Example
- Convert 10 kpa to psi:
- Multiply 10 by 0.145038
- 10 × 0.145038 = 1.45038 psi
- Convert 50 kpa to psi:
- Multiply 50 by 0.145038
- 50 × 0.145038 = 7.2519 psi
- Convert 100 kpa to psi:
- Multiply 100 by 0.145038
- 100 × 0.145038 = 14.5038 psi
- Convert 5 kpa to psi:
- Multiply 5 by 0.145038
- 5 × 0.145038 = 0.72519 psi

Conversion Definitions
kpa
Kilopascal (kpa) is a metric unit of pressure, where 1 kpa equals 1000 pascals, used to measure force per unit area in scientific and engineering contexts, especially in weather, construction, and fluid systems.
psi
Pounds per square inch (psi) is an imperial pressure unit representing force in pounds applied over one square inch, commonly used in tire pressures, hydraulics, and industrial applications in the United States.
Conversion FAQs
How accurate is the conversion from kpa to psi?
The conversion is precise because it uses the fixed ratio 0.145038, derived from exact definitions of pascals and psi. Minor measurement differences might occur depending on instrument calibration, but the formula itself remains accurate.
Can I convert any kpa value to psi using the same formula?
Yes, the same formula applies for any pressure value in kilopascals. Just multiply the kpa value by 0.145038 to get the equivalent psi measurement, regardless of the size of the number.
Why do different pressure units exist for the same measurement?
Different pressure units developed based on regional preferences, measurement systems, and historical standards. The metric system uses pascals, while the imperial system uses psi, leading to the need for conversion between the two.
What tools can I use to convert kpa to psi besides manual calculation?
Besides online calculators and conversion tools like the JavaScript tool above, physical conversion charts, scientific calculators, and smartphone apps can help quickly convert between kpa and psi.
