PSI to Bar Conversion – How It Works

PSI and bar are two of the most commonly used pressure units in engineering, automotive systems, and industrial applications.

✔ PSI to Bar Formula

$$\text{Bar} = \text{PSI} \times 0.0689476$$Bar=PSI×0.0689476

✔ Bar to PSI Formula

$$\text{PSI} = \text{Bar} \div 0.0689476$$PSI=Bar÷0.0689476

These formulas ensure accurate conversions every time.

Where these units are commonly used:

• Car tire pressure
• Air compressors
• Scuba diving pressure
• Mechanical engineering
• Hydraulic machinery
• HVAC systems
• Industrial pressure equipment

Example PSI and Bar Conversions

✔ Example 1: Convert 30 PSI to bar

$$30 \times 0.0689476 = 2.0684 \text{ bar}$$30×0.0689476=2.0684 bar

---

✔ Example 2: Convert 50 PSI to bar

$$50 \times 0.0689476 = 3.4474 \text{ bar}$$50×0.0689476=3.4474 bar

---

✔ Example 3: Convert 2 bar to PSI

$$2 \div 0.0689476 = 29.0076 \text{ PSI}$$2÷0.0689476=29.0076 PSI

---

✔ Example 4: Convert 1 bar

$$1 \div 0.0689476 = 14.5038 \text{ PSI}$$1÷0.0689476=14.5038 PSI
