Bar to Mpa ConverterRight in Your Browser
Convert bars (bar) to megapascals (MPa). The bar is a metric pressure unit almost equal to one atmosphere — standard for European tire pressures and diving. The megapascal (MPa) is one million pascals — the engineering unit for material strength and hydraulics. Everything is calculated locally in your browser — no server, and it works offline.

Frequently Asked Questions
How many megapascals are in a bar?
One bar equals 0.1 megapascals (1 bar = 0.1 MPa). So to go from bars to megapascals, multiply the bar value by 0.1.
What is the formula to convert bars to megapascals?
To convert bars to megapascals, multiply the bar value by 0.1. For example, 10 bar is 1 MPa.
What is 2.2 bars in megapascals?
2.2 bars — typical car tire pressure — is 0.22 megapascals. The converter above works for any value, entirely in your browser.
Is the bar to megapascal conversion exact?
The factor used here is the defined value: 1 bar = 0.1 MPa. Results are rounded to six significant digits for readability, so for high-precision work use the full factor.
