How to convert pascals to pounds per square inch
Unit conversion preserves the pressure reference. Gauge pressure and absolute pressure are different readings; changing between them also needs the ambient pressure. Mercury and water-column units use the conventions stated in their unit notes.
psi = Pa ÷ 6894.757293One pound per square inch corresponds to 6894.757293 pascals, so divide by that figure. Displayed constants may be rounded; the converter uses the stored factor before rounding the result.

Sources and precision
Table results are rounded to 8 significant digits; formula constants may be rounded to 10. Worked example answers use 6 significant digits. The converter starts at 6 significant digits and lets you change display precision. Calculations use the stored factors without intermediate rounding. Exact unit definitions do not make an input measurement more precise; conventional and measured factors follow the assumptions stated here.
