Convert one PSI to the corresponding pressure in kilopascal (kPa):

To convert pressure from pounds per square inch (PSI) to kilopascals (kPa), we use the conversion factor that 1 PSI is approximately equal to 6.89476 kPa.

When performing the conversion, you multiply the PSI value by this factor:

1 PSI × 6.89476 kPa/PSI = 6.89476 kPa

Rounding the result to a more manageable figure, it is often approximated as 6.894 kPa. This makes option B the most accurate choice for converting one PSI to kPa, as it closely corresponds to this derived value.

The other options either present values significantly higher or lower than the correct conversion, reflecting a misunderstanding of the conversion factor or calculation. Option B's approximate value aligns with standard conversion methodologies, making it the correct answer.
