Conversion Formula
The formula to convert psi to bar is: pressure in bar = pressure in psi × 0.0689476. This works because the bar is a metric unit of pressure, and 1 psi equals approximately 0.0689476 bar. Multiplying psi by this factor gives the pressure in bar. For example, 645 psi × 0.0689476 = 44.5 bar.
Conversion Example
- Convert 700 psi to bar:
- Step 1: Write the formula: bar = psi × 0.0689476
- Step 2: Plug in 700: 700 × 0.0689476
- Step 3: Calculate: 700 × 0.0689476 = 48.3 bar
- Convert 600 psi to bar:
- Step 1: Use formula: bar = 600 × 0.0689476
- Step 2: Multiply: 600 × 0.0689476 = 41.4 bar
- Convert 550 psi to bar:
- Step 1: Apply formula: bar = 550 × 0.0689476
- Step 2: Calculate: 550 × 0.0689476 = 37.9 bar

Conversion Definitions
psi
Psi, pounds per square inch, measures pressure by indicating how many pounds force is exerted on one square inch area. Widely used in the United States for tire pressures, hydraulics, and other pressure measurements, it reflects force over a specific area.
bar
Bar is a metric unit of pressure, equal to 100,000 pascals or Newtons per square meter. It is commonly used worldwide for meteorological, industrial, and scientific pressure measurements, offering a convenient alternative to psi for metric system users.
