Bars to Megapascals Converter
1 bar = 0.1 megapascals
1 bar equals 0.1 megapascals
How to convert bars to megapascals
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.
MPa = bar × 1/10One bar is 1/10 megapascals, so a single multiplication converts any value.

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.
