Converting Tire Pressure Units (PSI, Bars, kPa)
Tire pressure is typically measured in three different units: pounds per square inch (PSI), bars, and kilopascals (kPa). It’s important to know how to convert between these units to ensure you’re inflating your tires to the correct pressure.
Here’s a table summarizing the conversion factors:
| Unit | Conversion Factor |
|---|---|
| 1 PSI | 0.06895 bar |
| 1 bar | 100 kPa |
| 1 kPa | 0.145 PSI |
Example: Converting From PSI to Bars
Let’s say you’re trying to convert a tire pressure of 35 PSI to bars. Using the conversion factor from the table, we can calculate:
“`
35 PSI × 0.06895 bar/PSI = 2.418 bars
“`
Therefore, 35 PSI is equivalent to 2.418 bars.
Example: Converting From Bars to kPa
Now, let’s convert a tire pressure of 2.2 bars to kPa. Using the conversion factor, we calculate:
“`
2.2 bars × 100 kPa/bar = 220 kPa
“`
Therefore, 2.2 bars is equivalent to 220 kPa.
Troubleshooting Common Tire Pressure Gauge Issues
