36 psi is approximately 248.2 kpa.
To convert pounds per square inch (psi) to kilopascals (kpa), multiply the psi value by 6.89476, because 1 psi equals 6.89476 kpa. This conversion works because it reflects the relationship between the two pressure units, allowing for precise measurement when switching between imperial and metric systems.
Conversion Result and Explanation
When converting 36 psi to kpa, you multiply 36 by 6.89476, which results in roughly 248.2 kpa. This conversion is useful in contexts like tire pressure or hydraulic systems, where the pressure measurements are often expressed in either psi or kpa, depending on the country or industry standards.

Conversion Formula
The formula to convert psi to kpa is: kpa = psi × 6.89476. This works because 1 psi equals 6.89476 kpa, which is derived from the relationship between pounds-force per square inch and kilopascals. For example, to convert 36 psi, multiply 36 by 6.89476, giving 248.2 kpa.
Step-by-step: 36 × 6.89476 = 248.2 kpa. The multiplication takes the psi value and scales it to the metric system, where pressure is measured in kilopascals, ensuring accurate conversion based on the known unit equivalence.
Conversion Example
- Convert 20 psi to kpa:
- Step 1: Write the formula: 20 × 6.89476
- Step 2: Multiply 20 by 6.89476, which equals 137.8952
- Answer: 20 psi equals approximately 137.8952 kpa
- Convert 50 psi to kpa:
- Step 1: 50 × 6.89476
- Step 2: 344.738
- Result: 50 psi roughly 344.738 kpa
- Convert 10 psi to kpa:
- Step 1: 10 × 6.89476
- Step 2: 68.9476
- Answer: 10 psi equals about 68.9476 kpa

Conversion Definitions
psi
Psi, pounds per square inch, measures pressure by indicating how many pounds of force are applied over one square inch of area. It is a common unit in the US for tire and fluid pressure, reflecting force exerted per unit area in the imperial system.
kpa
Kilopascal (kpa) is a metric pressure unit representing 1,000 pascals, where one pascal equals one newton per square meter. It is widely used worldwide, especially in scientific and engineering contexts, to express pressure levels.
Conversion FAQs
How is psi related to pascals and kilopascals?
Psi is a pressure unit based on pounds-force per square inch, whereas pascals are the SI unit of pressure, defined as newtons per square meter. Kilopascals are multiples of pascals, where 1 kpa equals 1,000 pascals. To convert psi to pascals, multiply by 6894.76, then divide by 1,000 for kpa.
Why do different industries prefer psi or kpa for pressure measurements?
Industries choose units based on regional standards and measurement systems. The US favors psi because of imperial units, while most other countries use kpa or pascals due to the metric system. The choice influences compatibility and communication of pressure data globally.
What are common applications of psi and kpa?
Psi is often used in automotive tire pressures, hydraulic systems, and certain manufacturing processes in the US. Kpa is common in meteorology, scientific research, and international engineering projects where metric units are standard.
