Bar (bar) to Pascals (Pa) Conversion
Bar
The bar is a unit of pressure equal to exactly 100,000 pascals (100 kPa), accepted for use with the SI by the BIPM. It is close to one standard atmosphere (1 atm = 1.01325 bar) making it convenient for many practical applications. The bar is widely used in meteorology (weather maps), industrial gas and fluid systems, and tyre inflation in continental Europe. A typical car tyre is inflated to 2.2–2.5 bar; scuba diving tanks are filled to 200–300 bar.
Pascals
The pascal (Pa) is the SI derived unit of pressure, defined as one newton per square metre (N/m²), named after French mathematician Blaise Pascal who studied fluid pressure in the 17th century. Standard atmospheric pressure at sea level is 101,325 Pa (101.3 kPa). The pascal is a small unit for everyday use — a gentle breeze exerts approximately 1 Pa of dynamic pressure — so kilopascals (kPa) and megapascals (MPa) are more common in practical engineering contexts.
