Pressure Unit Converter

Hydraulic test work runs in bar on one side of the market and psi on the other, and standards state their limits in megapascals. This converts between them on the exact definition of the pound-force per square inch, 1 psi = 6 894.757 Pa, so 630 bar returns 9 137 psi rather than a figure rounded on the way through.

Usage Notes

Values are rounded to two decimal places on output. Negative inputs are rejected rather than converted: a gauge pressure below zero is a different measurement and belongs in a vacuum specification, not in a test hose enquiry.
