Convert bars to megapascals (bar to MPa)

Type a value in bars or in megapascals: the other field updates as you type. Below you will find the formula, a worked example and a bar to MPa chart.

Updated on

1 bar = 0.1 MPa

How to convert bars to megapascals

Formula: MPa = bar × 0.1

Worked example: 2.5 bar → 2.5 × 0.1 = 0.25 MPa

What is a bar?

The bar equals 100,000 pascals, very close to the atmospheric pressure at sea level. Europeans inflate car tires to about 2.2 to 2.5 bar, an espresso machine brews at around 9 bar and a full scuba tank holds about 200 bar.

What is a megapascal?

The megapascal equals one million pascals, or 10 bar. Engineers use it for the strength of concrete and steel and for hydraulic systems: ordinary structural concrete reaches a compressive strength of 20 to 40 MPa.

Frequently asked questions

How many megapascals are in a bar?

A bar equals 0.1 megapascals. To convert any value, multiply the number of bars by 0.1.

How do you convert bars to megapascals?

Use the formula MPa = bar × 0.1. Example: 2.5 bar → 2.5 × 0.1 = 0.25 MPa.

How many bars are in a megapascal?

A megapascal equals 10 bars. That is the reverse conversion, from megapascals to bars.
