Why Convert PSI to Kilopascals?

Converting between psi (psi) and kilopascals (kPa) is one of the most common pressure conversions. Whether for engineering, cooking, travel, or science, knowing how to quickly convert psi to kPa saves time and prevents errors.

Pressure conversions between psi and kPa are vital in automotive maintenance, meteorology, and scuba diving. Tire pressure affects fuel efficiency and safety, requiring drivers to convert between PSI and bar depending on the gauge used. Divers must strictly monitor pressure to avoid decompression sickness, often needing to convert depth and tank pressure readings. In weather forecasting, atmospheric pressure changes indicate approaching storms, with data often shared in different units globally. Failing to convert pressure accurately can lead to equipment failure, tire blowouts, or life-threatening situations underwater.

How to Convert PSI to Kilopascals

To convert psi to kilopascals, use the following formula:

kPa = psi × 6.894757293

Example: 1 psi = 6.894757293 kPa

For example, 5 psi = 34.47378647 kPa, 10 psi = 68.94757293 kPa, and 100 psi = 689.4757293 kPa. For larger values, 1000 psi = 6894.757293 kPa. Conversely, 1 kPa = 0.1450377377 psi. Our calculator above performs this conversion instantly with full precision — no rounding errors.

Common Mistakes to Avoid

Gauge vs Absolute: confusing gauge pressure (psig) with absolute pressure (psia).
Bar vs Pascal: 1 Bar is 100,000 Pascals, not 10 or 100.
Atmosphere variations: confusing standard atm with technical atm.

Pro Tips

Tire checks: Check tire pressure when cold (tires heat up and pressure rises while driving).
PSI rule: Typical car tires are 30-35 PSI.
Altitude effect: Air pressure drops as you go higher (ears popping).

What is a PSI?

PSI (Pounds per Square Inch) is a unit of pressure in the Imperial and US customary systems. It represents the force of one pound-force applied to an area of one square inch.

PSI is the standard unit for tire pressure, industrial hydraulics, and compressed gas systems in the United States and UK.

What is a Kilopascal?

A unit of pressure equal to 1,000 Pascals.

Meteorology and tire pressure.
