A tire pressure gauge reads 33.0 pounds per square inch. How many kPa is this?

(Note: Multiple steps may be required in the conversion.)

Answer :

To convert a tire pressure from pounds per square inch (psi) to kilopascals (kPa), you can use a specific conversion factor. The conversion factor between psi and kPa is as follows:

1 psi = 6.89476 kPa

Here’s how you can convert 33.0 psi to kPa:

1. Identify the Pressure in psi: The given tire pressure is 33.0 psi.

2. Use the Conversion Factor: We know that 1 psi equals 6.89476 kPa.

3. Perform the Conversion:
- Multiply the pressure in psi by the conversion factor to get the equivalent pressure in kPa.
- Calculation: [tex]\( 33.0 \, \text{psi} \times 6.89476 \, \text{kPa/psi} = 227.53 \, \text{kPa} \)[/tex]

So, 33.0 psi is equal to approximately 227.53 kPa.
