745 Torr to Atm: A Comprehensive Guide to Pressure Conversion

Understanding Pressure Measurement

Pressure, a fundamental property of a gas or liquid, represents the force exerted per unit area. It plays a crucial role in various scientific, engineering, and everyday applications. Two commonly used units of pressure are torr and atmosphere (atm).

Torr
Named after the Italian physicist Evangelista Torricelli, torr is a unit of pressure defined as 1/760 of the standard atmospheric pressure at sea level. It is frequently used in vacuum technology and meteorology.

Atmosphere
The atmosphere, abbreviated as atm, is defined as the average pressure at sea level at 0°C (273.15 K) and a latitude of 45°. It is the standard unit of pressure in many scientific and technical fields.

Converting 745 Torr to Atm

To convert 745 torr to atm, divide the pressure value in torr by the conversion factor of 760 torr/atm.

745 torr to atm

745 torr ÷ 760 torr/atm = 0.98026 atm (rounded to five decimal places)

Therefore, 745 torr is approximately equal to 0.98026 atm.
