Pressure Converter
Calculation
Conversions use standard multiplication factors (e.g., 1 Pa = 0.000145 psi).
Understanding Pressure Conversion
Pressure is defined as the force applied perpendicular to the surface of an object per unit area over which that force is distributed. A pressure converter translates measurements between different units of pressure, such as Pascals (Pa, the SI unit), kilopascals (kPa), bars, pounds per square inch (psi), atmospheres (atm), and millimeters of mercury (mmHg or Torr).
The study of pressure, particularly atmospheric and fluid pressure, advanced significantly in the 17th century with scientists like Evangelista Torricelli (inventor of the barometer) and Blaise Pascal (whose work led to the SI unit being named after him). Different units arose from various applications: psi in engineering (especially in the US), atmospheres for standard atmospheric pressure, mmHg in meteorology and medicine (blood pressure), and Pascals/bars in scientific and international contexts.
Pressure conversion is vital in meteorology, fluid mechanics, engineering, materials science, and medicine. It's used for weather forecasting, designing hydraulic systems, specifying tire pressure, measuring altitude, monitoring blood pressure, and in countless industrial processes. This tool allows easy switching between these various units.
