Pascal (unit)
Videos
The pascal is the unit of pressure in the International System of Units. It is also used to quantify internal pressure, stress, Young's modulus, and ultimate tensile strength. The unit, named after Bl
A pressure gauge reading in psi (red scale) and kPa (black scale)
Bar (unit)
Videos
The bar is a metric unit of pressure defined as 100000 Pa, though not part of the International System of Units. A pressure of 1 bar is slightly less than the average atmospheric pressure on Earth at
Pascal (unit)
…also equivalent to 10 barye (10 Ba) in the CGS system. Common multiple units of the pascal are the hectopascal (1 hPa = 100 Pa), which is equal to one millibar, and the kilopascal (1 kPa = 1,000 Pa), which is equal to one centibar. The unit of measurement called standard atmosphere (atm) is defined as 101325…
