Quick Answer

Exact: 1 PSI = 0.0689476 bar = 6.89476 kPa.

Formulas: bar = PSI×0.0689476, kPa = PSI×6.89476.

Example: 32 PSI (car) = 2.2067 bar = 220.67 kPa. Triple table 10-100 PSI below.

Formula & 1-10 Table

• 10 PSI = 0.6895 bar = 68.95 kPa
• 20 PSI = 1.3790 bar = 137.90 kPa
• 30 PSI = 2.0684 bar = 206.84 kPa
• 40 PSI = 2.7579 bar = 275.79 kPa
• 50 PSI = 3.4474 bar = 344.74 kPa
• 60 PSI = 4.1369 bar = 413.69 kPa
• 70 PSI = 4.8263 bar = 482.63 kPa
• 80 PSI = 5.5158 bar = 551.58 kPa
• 90 PSI = 6.2053 bar = 620.53 kPa
• 100 PSI = 6.8948 bar = 689.48 kPa

Where You'll Use This

• Daily life - shopping, travel, recipes, or work specs need exact conversion.
• Avoid 20 percent errors - check US vs UK and metric vs imperial.
• Try our live converter - type once, see every unit, copy instantly.

How to use the converter in 3 steps

1. Step 1: Select your From and To units (e.g., cm to inches).
2. Step 2: Type the amount - every unit updates as you type.
3. Step 3: Copy with the copy icon.

Common mistakes to avoid

• Mixing US vs UK systems - gallon, pint, and stone differ. Always check source.
• Rounding too early - keep full factor until final display, then round to 2 decimals.
• Using 1000 instead of 1024 for digital storage - RAM uses 1024, drive makers use 1000.

Always double-check your source system and use exact factor from BIPM or NIST.
