Conversion Definitions
Bar
A bar is a unit of pressure measuring force per unit area, equal to 100,000 pascals, or roughly the atmospheric pressure at sea level, used widely in meteorology and engineering for pressure measurements.
Psi
Pounds per square inch (psi) is a pressure unit measuring force in pounds applied over one square inch, commonly used in the United States for tire pressures, hydraulics, and industrial applications.
Conversion FAQs
How accurate is the conversion from bar to psi?
The conversion is highly precise because it’s based on a fixed ratio of 14.5038 psi per 1 bar. Minor variations may occur due to rounding but generally, the result is sufficiently accurate for most practical uses.
Can I convert negative pressure values from bar to psi?
Yes, the same formula applies. Negative pressure indicates a vacuum or lower than atmospheric pressure, and multiplying by 14.5038 converts it to psi, showing how much less than atmospheric pressure it is.
Is there a quick way to memorize the conversion factor?
Remember that 1 bar equals about 14.5 psi, so multiplying bar values by 14.5 gives an approximate psi value. For exact calculations, use 14.5038, but 14.5 is close enough for rough estimates.
