Bar to Psi Conversion - Convert Psi (psi) to Bar (bar).
Result:
Our Bar to Psi converter is the perfect tool to quickly convert pressure from bar to psi or vice versa. On this page, we'll talk about how to convert bar to psi, understand how to use this bar to psi converter, and answer some common questions about this conversion.
What are Bar and Psi?
Pounds per square inch (psi) is a pressure unit based on the avoirdupois pound-force. One psi is the pressure caused by one pound-force of force acting on a square-inch surface area. Psi is used in various systems to measure pressure and stress.
A bar is a metric pressure unit equal to 100,000 pascals (105 Pa). Although not an SI unit itself, bar is widely used, especially by meteorologists and engineers when pascal values would be too large.
Why Convert Between Bar and Psi?
While the metric system is widely used in science, U.S. customary units like psi are still common in some industries like automotive and construction. Being able to convert between bar and psi is useful when you need to understand pressure readings using different unit systems.
Understanding Pressure Units
A bar measures pressure as the force applied perpendicular to a surface, with 1 bar equaling 100,000 pascals. Atmospheric pressure at sea level is very close to 1 bar.
Psi (pounds per square inch) measures the pressure exerted over one square inch of area. It is defined as 1 pound-force acting on 1 square inch. Atmospheric pressure at sea level is around 14.7 psi.
Other Pressure Units
Some other common units used to measure pressure include:
- Pascal (Pa) - The SI base unit for pressure
- Atmosphere (atm) - Approximately equal to air pressure at sea level
- Millimeters of mercury (mmHg) - Used for measuring low pressures like blood pressure
Converting Bar to Psi
To convert from bar to psi, you multiply the bar value by a fixed conversion factor:
pressure in psi = pressure in bar x 14.50377
For example, if the pressure is 32.5 bars:
pressure in psi = 32.5 bars x 14.50377 = 471.3725 psi
Bar to Psi Conversion Rate
The conversion rate of 14.50377 accounts for the differences in unit definitions between bar and psi.
Converting Psi to Bar
To convert from psi to bar, you divide the psi value by the conversion factor:
pressure in bar = pressure in psi / 14.50377
For example, to convert 232 psi to bar:
pressure in bar = 232 psi / 14.50377 = 15.99584 bar
How to Use This Pressure Converter
Using this converter to switch between bar and psi units is simple:
- Enter the pressure value for either bar or psi in the specified field.
- Click on the convert button.
- The result will be shown in the second field
This allows you to quickly convert pressures between bar, and psi!
Accuracy and Significant Figures
When converting, make sure to pay attention to significant figures and round appropriately. Most pressure measurements only require 2-3 significant digits.
Applications in Different Industries
Pressure units and conversions are important across many industries including:
- Automotive (tire pressure, engine systems)
- Aviation (altitude pressure readings)
- Oil & Gas (well pressures)
- Heating & Cooling (HVAC systems)
- Science & Research Labs
