Torr to PSI Converter

A torr is a unit of pressure equal to 1/760 of an atmosphere, approximately 133.322 pascals. Named after Evangelista Torricelli, it's commonly used in vacuum technology and low-pressure applications.

The torr was named after Evangelista Torricelli, inventor of the barometer, and became standard in vacuum technology. It provided a convenient unit for low-pressure measurements, particularly in scientific instruments and vacuum systems.

Torr is extensively used in vacuum technology, scientific instruments, and low-pressure applications. It's standard for vacuum pump specifications, mass spectrometry, and scientific equipment operating under reduced pressure conditions.

Pounds per square inch (psi) is a unit of pressure representing the pressure exerted by one pound-force applied to an area of one square inch. It's widely used in the United States for various pressure applications.

PSI developed with the imperial system and became standard in American engineering and industry. It provided an intuitive pressure unit based on familiar force and area measurements, becoming deeply embedded in US industrial and automotive applications.

PSI is extensively used in the United States for tire pressure, hydraulic systems, pneumatic tools, and industrial applications. It's standard for automotive tire specifications, air compressor ratings, and hydraulic system pressures in American industry.
