Conversion Definitions
Bar
The bar is a metric unit of pressure, measuring force per unit area, where 1 bar equals 100,000 pascals, roughly equivalent to Earth’s atmospheric pressure at sea level. It is used in meteorology, engineering, and other fields to specify pressure levels.
Psi
Pounds per square inch (psi) is a pressure unit common in the US, measuring force applied over an area of one square inch, based on the imperial system. It is often used in tire pressure, hydraulics, and other industrial contexts to quantify pressure.
Conversion FAQs
What does it mean if 3.3 bar equals 47.89 psi?
This means that a pressure of 3.3 bar exerts the same force per unit area as 47.89 pounds applied over each square inch. It helps translate pressure measurements between metric and imperial units for various applications.
How accurate is the conversion from bar to psi?
The conversion is highly accurate because it uses a fixed, internationally recognized conversion factor of 14.5038. Unless the pressure measurement is extremely high or low, results will closely match actual pressure values.
Can I convert psi back to bar using this method?
Yes, to convert psi to bar, divide the psi value by 14.5038. For example, 47.89 psi divided by 14.5038 equals approximately 3.3 bar, completing the reverse calculation.
Why is the conversion factor 14.5038?
This factor comes from the precise definition of the pound-force and pascal units, establishing the exact relationship between bar and psi, ensuring consistent and accurate conversions across scientific and industrial uses.
