Convert between PSI, Bar, Pascal, and atmospheric pressure units. Essential for engineering, weather analysis, and industrial applications.
PSI is a unit of pressure commonly used in the United States and various industries. It measures the amount of force exerted on an area of one square inch. This unit is widely used in automotive tire pressure, hydraulic systems, and plumbing applications.
The bar is a metric unit of pressure commonly used in meteorology, engineering, and industry. One bar is equal to 100,000 Pascals (Pa). It is often used to measure atmospheric pressure and in industrial applications such as compressed air systems.
The Pascal is the SI unit of pressure, named after Blaise Pascal, a French mathematician and physicist. It is defined as one Newton per square meter. The Pascal is widely used in scientific calculations, meteorology, and engineering.
Atmospheric pressure (ATM) is the pressure exerted by the weight of air in the Earth's atmosphere. At sea level, the standard atmospheric pressure is approximately 101.325 kPa (kilopascals) or 1 ATM. This unit is commonly used in physics, chemistry, and aviation.
