13 psi is approximately 89.585 kpa.
This conversion takes the pressure measured in pounds per square inch (psi) and changes it into kilopascals (kpa). Since 1 psi equals 6.89476 kpa, multiplying 13 by that value gives the result in kpa.
Pressure Conversion from psi to kpa
To convert psi to kpa, you multiply the psi value by 6.89476 because it’s the fixed ratio between these two units. This ratio is derived from the definition that 1 psi equals 6.89476 kilopascals, which is based on the metric system’s standard units of pressure.

Conversion Formula
The conversion from psi to kpa is done through multiplication by 6.89476 because 1 psi equals exactly 6.89476 kpa. For example, if you have 10 psi, multiplying 10 by 6.89476 results in 68.9476 kpa, which is the equivalent pressure in metric units.
Conversion Example
- Convert 20 psi to kpa:
- Multiply 20 by 6.89476
- 20 × 6.89476 = 137.8952 kpa
- This means 20 psi equals 137.8952 kpa
- Convert 5 psi to kpa:
- 5 × 6.89476 = 34.4738 kpa
- So, 5 psi is 34.4738 kpa
- Convert 15 psi to kpa:
- 15 × 6.89476 = 103.4214 kpa
- Therefore, 15 psi is 103.4214 kpa
- Convert 0 psi to kpa:
- 0 × 6.89476 = 0 kpa
- Zero psi equals zero kpa
- Convert 50 psi to kpa:
- 50 × 6.89476 = 344.738 kpa
- Thus, 50 psi equals 344.738 kpa

Conversion Definitions
Psi (pounds per square inch) measures pressure by how many pounds of force are applied over one square inch of area. Kilopascal (kpa) is a metric unit representing pressure, equal to 1,000 pascals, where a pascal is a force of one newton per square meter.
Psi is a unit originating from the Imperial system, mainly used in the US for pressure readings; kpa derives from the metric system and is standard worldwide, especially in scientific and technical applications. Both express how much force is applied over a specific area.
Conversion FAQs
How precise is the conversion from psi to kpa?
The conversion is extremely precise because it uses a fixed ratio of 6.89476. Minor differences can occur in practical measurements due to rounding, but for most applications, the conversion provides an accurate reflection of pressure values.
Can I convert negative psi values to kpa?
Yes, negative psi values also convert into negative kpa, indicating a vacuum or pressure below atmospheric level. The same ratio applies, so multiply the negative psi by 6.89476 to find the kpa equivalent.
Why is psi still used in some countries instead of kpa?
Psi remains popular in certain regions, especially the US, because of historical usage and familiarity. Industries like automotive and aviation often use psi due to legacy standards, even though kpa is more common internationally for scientific purposes.
What equipment measures pressure in psi as opposed to kpa?
Pressure gauges like tire pressure meters, certain hydraulic systems, and some industrial instruments are calibrated in psi. In contrast, many scientific and international instruments prefer kpa or pascals for measurement.
Is converting 13 psi to kpa useful in everyday applications?
Absolutely, converting psi to kpa helps in contexts like tire inflation, weather pressure readings, and engineering projects, especially when working with international standards or scientific data that favor the metric system.
