The conversion of 70 kpa to psi is approximately 10.15 psi.
To convert from kilopascal (kpa) to pounds per square inch (psi), multiply the kpa value by 0.145038. This conversion works because 1 kpa equals exactly 0.145038 psi, based on the definitions of these pressure units. Therefore, 70 kpa times 0.145038 gives the psi value.
Understanding the Conversion from Kpa to Psi
The formula used is: psi = kpa × 0.145038. This is because 1 kilopascal equals 0.145038 pounds per square inch. To convert any kpa value to psi, you simply multiply it by 0.145038. For example, 70 kpa × 0.145038 = 10.15266 psi, which rounds to 10.15 psi. This method ensures accurate measurement translation between the units.

Conversion Formula
The formula to convert kpa to psi is: psi = kpa × 0.145038. This is because the two units are related through their definitions; 1 kpa equals 0.145038 psi. The multiplication adjusts the pressure value from kilopascals to pounds per square inch, making it compatible for use in different contexts. For example, converting 50 kpa: 50 × 0.145038 = 7.2519 psi, which shows that 50 kpa equals about 7.25 psi.
Conversion Example
- Convert 100 kpa:
- Multiply 100 by 0.145038

Conversion Definitions
kpa
Kilopascal (kpa) is a unit of pressure measurement, where 1 kpa equals 1,000 pascals, used to quantify force per unit area in physics and engineering contexts. It is part of the metric system, providing a standard way to measure pressure in scientific and industrial applications.
psi
Pounds per square inch (psi) is a pressure unit measuring force in pounds applied over one square inch area. Commonly used in the United States, it is often found in tire pressure, fluid pressure systems, and various engineering fields for practical pressure readings.
Conversion FAQs
What is the best way to remember that 1 kpa equals 0.145038 psi?
The easiest way is to memorize the approximate conversion factor 0.145, which is close enough for most practical purposes. Alternatively, remember that 1 kpa is roughly 14.5% of a psi, making mental estimates quicker but less precise for detailed calculations.
Can I convert kpa to psi without a calculator?
Yes, by using approximate mental math: multiplying by 0.15 gives a close estimate, while multiplying by 0.145038 is more precise. For quick approximations, multiplying the kpa value by 0.15 is often sufficient, but for accuracy, use a calculator or the conversion tool.
What are common uses of kpa and psi in everyday life?
Kpa is often used in scientific contexts, such as measuring atmospheric pressure or in weather reports. Psi is common for tire pressures, hydraulic systems, and pressure gauges in household and industrial settings, making both units relevant for consumers and professionals.
