The Pascal (Pa) in Pressure

What is Pascal (Pa)

The Pascal (Pa) is the SI unit of pressure and is defined as one newton per square meter, denoted as 1 Pa=1 N/m2. It is named after the French mathematician, physicist, and inventor Blaise Pascal. The unit measures the amount of force applied over a particular area, making it essential for various applications in physics, engineering, and meteorology.

In practical terms, the Pascal is a relatively small unit of pressure. It is commonly used in scientific contexts and fields that require precise measurements. For instance, atmospheric pressure at sea level is approximately 101,325 Pa, which is often expressed in larger units due to its magnitude.
