What is the difference between bar and psi?

Bar is a metric-related pressure unit equal to 100,000 pascals, while psi is an Imperial unit representing pounds per square inch of force.

Why do I need to convert bar to psi?

Converting from bar to psi is essential when using tools, equipment, or standards that are specified in Imperial or US customary units.

Is the conversion from bar to psi exact?

The conversion uses a fixed rate of 1 bar = 14.503773773 psi, but rounding can cause minor differences in precise calculations.
