1.3 psi equals approximately 0.0898 bar.

This conversion is based on the fact that 1 psi (pound per square inch) equals about 0.0689476 bar. By multiplying 1.3 psi by this factor, we get the equivalent pressure in bar, which helps in understanding pressure measurements across different units.

Pressure Conversion from psi to bar

To convert psi to bar, you multiply the psi value by 0.0689476. This works because psi and bar are both units of pressure, but they are based on different standards of measurement. The conversion factor is derived from the relationship between pounds per square inch and the metric unit bar.

Conversion Tool

Conversion Formula

The formula to convert psi to bar is: bar = psi × 0.0689476. This works because 1 psi is defined as 1 pound-force per square inch, and 1 bar equals 100,000 pascals. Since 1 psi equals approximately 6894.76 pascals, dividing by 100,000 gives the conversion factor.

For example, converting 1.3 psi involves multiplying 1.3 by 0.0689476, resulting in approximately 0.0898 bar. The calculation is: 1.3 × 0.0689476 = 0.0898.

Conversion Example

• Convert 2 psi to bar:
  • Step 1: Write the formula: bar = psi × 0.0689476.
  • Step 2: Substitute psi with 2: 2 × 0.0689476.
  • Step 3: Perform the multiplication: 0.1379.
  • Result: 2 psi equals approximately 0.1379 bar.
• Convert 5 psi to bar:
  • Step 1: Use the formula: bar = 5 × 0.0689476.
  • Step 2: Calculate: 0.3447.
  • Result: 5 psi equals about 0.3447 bar.
• Convert 0.5 psi to bar:
  • Step 1: Apply the formula: bar = 0.5 × 0.0689476.
  • Step 2: Calculate: 0.0345.
  • Result: 0.5 psi equals roughly 0.0345 bar.

Conversion Definitions

psi

Psi, or pounds per square inch, is a pressure unit based on the force of one pound applied over an area of one square inch. It’s predominantly used in the United States for measuring tire pressures, hydraulic systems, and other pressure-related applications.

bar

Bar is a metric pressure unit equal to 100,000 pascals, roughly the atmospheric pressure at sea level. It’s used in various scientific, industrial, and meteorological contexts to describe pressure measurements across many countries outside the US.

Conversion FAQs

How accurate is the conversion from psi to bar for small values like 1.3 psi?

The conversion is highly accurate because it relies on a fixed mathematical factor. For small values such as 1.3 psi, the result in bar is precise up to four decimal places, making it suitable for most practical and scientific purposes.

Can I convert psi to bar manually without a calculator?

Yes, by multiplying the psi value by 0.0689476, you can convert psi to bar manually. For quick estimations, approximate the factor as 0.069, but for exact results, use the precise value or a calculator.

What are typical pressure ranges in bar for household applications?

Household water systems usually operate around 2 to 4 bar, while car tires are typically inflated to about 2 to 3 bar. Knowing the conversion helps in understanding these pressures in different units, especially when using pressure gauges calibrated in psi.
