What is Pressure?
Pressure is the force applied perpendicular to a surface per unit area: P = F / A. The SI unit is the pascal (Pa), equal to one newton per square metre (1 Pa = 1 N/m²). Practical applications use larger units: the bar (1 bar = 100,000 Pa, close to standard atmospheric pressure), atmosphere (atm) (1 atm = 101,325 Pa), and psi (pounds per square inch, used in the US for tire and gas pressures). Blood pressure is measured in mmHg (millimetres of mercury), also called torr.
What is Femtopascal?
The femtopascal (symbol: fPa) is an SI-derived unit of pressure equal to one quadrillionth (10-15) of a pascal. It is used in scientific research, nanotechnology, vacuum science, and precision measurements involving extremely small pressure values. The femtopascal uses the SI prefix femto, representing a factor of 10-15.
One femtopascal is equal to 0.000000000000001 pascal, 1,000 attopascals, 0.001 picopascal, 1×10-20 bar, and 9.86923×10-21 standard atmosphere. The femtopascal is part of the SI pressure scale for representing ultra-low pressure values.
What is Standard Atmosphere?
The standard atmosphere (symbol: atm) is a non-SI unit of pressure defined as exactly 101,325 pascals. It represents the average atmospheric pressure at sea level under standard conditions and is widely used in chemistry, physics, meteorology, and engineering. The standard atmosphere provides a convenient reference for pressure measurements and scientific calculations. Additional information is available in the standard atmosphere reference.
One standard atmosphere is equal to 101,325 pascals, 1.01325 bars, 101.325 kilopascals, 14.6959 pounds per square inch, and 760 millimeters of mercury. The standard atmosphere is one of the most important reference units in science and engineering.
