Conversion result: 12 psi equals approximately 82.74 kpa.

To convert pounds per square inch (psi) to kilopascals (kpa), you multiply the psi value by 6.89476 because 1 psi equals 6.89476 kpa. So, for 12 psi, you do 12 times 6.89476, which gives the result in kpa.

Conversion Result and Explanation

12 psi is roughly 82.74 kpa. This conversion is based on the fact that pressure measurements in psi can be translated into kpa by using the fixed conversion factor of 6.89476. Multiplying the psi value by this number gives you the equivalent pressure in kpa.

Conversion Formula

The formula to convert psi to kpa is: kpa = psi × 6.89476. This works because 1 psi is defined as exactly 6.89476 kilopascals. Therefore, multiplying the psi value by this number gives the pressure in kpa. For example, 12 psi equals 12 × 6.89476 = 82.73712 kpa.

Conversion Example

• Convert 20 psi to kpa:
  • Step 1: Write the formula: kpa = psi × 6.89476.
  • Step 2: Substitute 20 for psi: kpa = 20 × 6.89476.
  • Step 3: Calculate: 20 × 6.89476 = 137.8952 kpa.
  • Result: 20 psi equals 137.8952 kpa.
• Convert 5 psi to kpa:
  • Step 1: Use the formula: kpa = psi × 6.89476.
  • Step 2: Replace psi with 5: kpa = 5 × 6.89476.
  • Step 3: Perform multiplication: 5 × 6.89476 = 34.4738 kpa.
  • Result: 5 psi equals 34.4738 kpa.
• Convert 50 psi to kpa:
  • Step 1: Write the formula: kpa = psi × 6.89476.
  • Step 2: Substitute 50: kpa = 50 × 6.89476.
  • Step 3: Calculate: 50 × 6.89476 = 344.738 kpa.
  • Result: 50 psi equals 344.738 kpa.

Conversion Definitions

psi

Psi, pounds per square inch, measures pressure based on the force of one pound applied over one square inch of area. It is a common unit in the US for tire pressure, blood pressure, and other pressure measurements, with 1 psi equaling approximately 6.89476 kpa.

kpa

Kilopascal, abbreviated as kpa, is a metric unit measuring pressure or stress. It equals 1000 pascals, where a pascal is one newton per square meter. Kpa is widely used in engineering, meteorology, and physics to quantify pressure, with 1 kpa being about 0.145 pounds per square inch.

Conversion FAQs

How accurate is converting psi to kpa using the factor 6.89476?

The conversion factor 6.89476 is exact, as it is defined by international standards. Multiplying psi by this number yields precise pressure conversions to kpa, making it reliable for scientific and engineering applications where accuracy is critical.

Can I convert psi to kpa manually without a calculator?

Yes, but it may be less precise. You can estimate by knowing that 1 psi is roughly 7 kpa. For more exact results, multiplying by 6.89476 is best, but for quick approximations, multiplying psi by 7 gives a close estimate.

What are common uses of psi and kpa in industry?

Psi is often used for tire pressures, blood pressure readings, and pressure in small-scale systems. Kpa is preferred for large-scale industrial processes, building codes, and scientific measurements where the metric system is standard, ensuring consistency across international applications.
