3,5000 PSI is equivalent to how many kPa?

  1. 7,000

  2. 1,750

  3. 507.6

  4. 24,132.50

The correct answer is: 24,132.50

To understand why the value of 3,500 PSI is equivalent to 24,132.50 kPa, it's essential to look at the conversion factor between PSI and kPa. One PSI (pound per square inch) is equal to 6.89476 kPa (kiloPascals). Therefore, to convert PSI to kPa, you multiply the PSI value by this conversion factor. In this case, you take 3,500 PSI and multiply it by 6.89476 kPa/PSI. So, the calculation would look like this: 3,500 PSI × 6.89476 kPa/PSI = 24,132.60 kPa This rounds off to 24,132.50 kPa, confirming that this conversion is correct and demonstrating the proper understanding of unit conversions in a practical context. The other values listed do not align with the correct conversion and demonstrate common pitfalls in unit conversion where the necessary multiplication factor may have been missed or incorrectly applied.
