Pascal to Bar Converter

A pascal (Pa) is the SI unit of pressure, defined as one newton per square meter (N/m²). It represents the pressure exerted by a force of one newton uniformly distributed over an area of one square meter.

The pascal was named after French mathematician and physicist Blaise Pascal in 1971 and became the SI unit of pressure. It replaced various traditional pressure units and provided a unified measure based on fundamental SI units of force and area.

Pascals are universally used in scientific and engineering applications for pressure measurements. They're standard in physics, engineering calculations, materials science, and form the basis for all other pressure unit conversions in the SI system.

A bar is a unit of pressure equal to 100,000 pascals (10⁵ Pa), approximately equal to atmospheric pressure at sea level. It's widely used in meteorology, engineering, and industrial applications as a practical pressure unit.

The bar was introduced in 1909 as a convenient unit close to atmospheric pressure. It became widely adopted in meteorology and engineering because it provided a practical scale for atmospheric and industrial pressure measurements.

Bars are extensively used in meteorology, industrial pressure systems, automotive applications, and engineering. They're standard for weather maps, industrial pressure gauges, automotive turbocharger specifications, and hydraulic system ratings.
