bar [bar] to megapascal [MPa] Converter

Quick Reference

1 bar (bar) = 0.1 megapascal (MPa)

1 megapascal (MPa) = 10 bar (bar)

How to Convert bar to megapascal

1 bar = 0.1 MPa
1 MPa = 10 bar

To convert bar to megapascal, divide the value by 10 (equivalently, multiply by 0.1). To convert megapascal back to bar, multiply by 10.

Example: convert 10 bar to MPa:
10 bar = 10 x 0.1 = 1 MPa

↔ Convert megapascal to bar

bar

Definition: The bar (symbol: bar) is a metric unit of pressure, but not part of the International System of Units (SI). It is defined as exactly equal to 100,000 Pa (100 kPa), which is slightly less than current average atmospheric pressure on Earth at sea level.

History/origin: The bar was introduced by British meteorologist William Napier Shaw in 1909.

Current use: The bar is used in various fields, including meteorology, diving (for measuring pressure underwater), and industrial applications. It is often used when a unit close to atmospheric pressure is convenient.

megapascal

Definition: The megapascal (symbol: MPa) is a multiple of the pascal, which is the SI unit of pressure and stress. One MPa is equal to 1,000,000 pascals.

History/origin: Like the pascal, the megapascal's origin is tied to the development of SI units. It provides a more convenient scale for expressing large pressures.

Current use: Megapascals are frequently used in engineering, especially in the fields of material science, structural engineering, and geomechanics, for measuring the strength of materials, stresses in structures, and pressures in geological formations.
