Pascals to Inches of Mercury Converter
1 pascal ≈ 0.000295299805 inches of mercury
1 pascal equals 0.0002953 inches of mercury
How to convert pascals to inches of mercury
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.
inHg = Pa ÷ 3386.38896One inch of mercury corresponds to 3386.38896 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.
