Conversion Formula
The formula for converting psi to kpa is: Pressure in kpa = psi value × 6.89476. This works because 1 psi equals exactly 6.89476 kpa. To perform the conversion, multiply the psi value by this factor. For example, 3 psi times 6.89476 equals 20.68428 kpa, which is the pressure in kilopascals. This simple multiplication makes converting between these units quick and accurate as they are based on fixed conversion factors, allowing for seamless unit conversions in technical calculations.
Conversion Example
- Convert 5 psi to kpa:
- Step 1: Write down the psi value (5).
- Step 2: Multiply 5 by 6.89476.
- Step 3: 5 × 6.89476 = 34.4738 kpa.
- Step 4: The pressure of 5 psi equals approximately 34.4738 kpa.
- Convert 10 psi to kpa:
- Step 1: Take the value 10.
- Step 2: Multiply 10 by 6.89476.
- Step 3: 10 × 6.89476 = 68.9476 kpa.
- Step 4: Result shows that 10 psi equals about 68.9476 kpa.
- Convert 1.5 psi to kpa:
- Step 1: Use the value 1.5.
- Step 2: Multiply 1.5 by 6.89476.
- Step 3: 1.5 × 6.89476 = 10.34214 kpa.
- Step 4: So, 1.5 psi equals approximately 10.34214 kpa.
