## What is bar?

The **bar** is a non-SI unit of pressure equal to 100,000 pascals (1 bar = 100,000 Pa), the SI derived unit of pressure. It is also equal to 100 kilopascals (kPa), or 0.1 megapascals (MPa), or 0.986923267 atmospheres (atm), or 1,000 millibars (mbar), or 750.06168 millimeters of mercury at 0 °C (mmHg), or 401.463 inches of water at 4 °C (inH2O), or 14.50379 pounds per square inch (psi), or 2,088.54343 pounds per square foot (psf) or 750.06168 torr (Torr).

The bar is equal to 1,000,000 dynes per square centimeter (1 bar = 1,000,000 dyn/cm²). The dyne (dyn) is a unit of force in the centimetre-gram-second (CGS) system of units while the square centimeter (cm²) is a unit of area in the SI.

The bar is used worldwide as a unit of pressure in meteorology, engineering and automotive field.
