Common Scenarios
Pressure conversion is an important reference in mechanical engineering, meteorology, and medicine. When inflating car tires, gauges often show psi or bar; in repair shops, mechanics might use kg/cm² or kPa. Weather forecasts use hectopascals (hPa).
History & Background
In the 17th century, Torricelli conducted his famous mercury column experiment and invented the barometer. In the 19th century, the Industrial Revolution and steam engines created a need to measure steam pressure, leading to the "standard atmosphere (atm)."
Conversion Details
Pressure conversion is based on the pascal (Pa).
Common conversions: 1 atm = 101.325 kPa = 760 mmHg, 1 bar = 100 kPa ≈ 14.504 psi.
