How to Convert PSI to kPa: A Complete Guide

Converting PSI (pounds per square inch) to kPa (kilopascals) is essential for accurately measuring pressure in various applications. One PSI equals approximately 6.89476 kPa. This conversion allows you to switch between imperial and metric units easily, ensuring precision in tire pressures, gas pipelines, and engineering contexts.

What Is the Formula to Convert PSI to kPa?

To convert PSI to kPa, multiply the PSI value by 6.89476:

$$\text{kPa}=\text{PSI}\times 6.89476$$

For example, 35 PSI converts to:

$$35\times 6.89476=241.3166\text{ kPa}$$

How Does kPa Relate to Other Pressure Units?

The kilopascal (kPa) is a metric unit equal to 1,000 pascals (Pa), where 1 Pa equals 1 newton per square meter. PSI is an imperial unit based on pounds-force per square inch. Converting between these units is vital for international standards and scientific accuracy.

What Are Practical Examples of PSI to kPa Conversion?

• Tire pressure: A recommended tire pressure of 32 PSI equals approximately 220.63 kPa.
• Scuba tanks: 3,000 PSI is about 20,684 kPa.
• Industrial gas pipelines: Pressures often expressed in kPa can be converted to PSI for equipment calibration.

How to Convert kPa Back to PSI?

To convert kPa to PSI, divide the kPa value by 6.89476:

$$\text{PSI}=\frac{\text{kPa}}{6.89476}$$

For example, 100 kPa equals:

$$\frac{100}{6.89476}=14.5038\text{ PSI}$$
