The Conversion Formula
To convert atmospheres to torr, multiply the value by the conversion factor: 1 atm = 760 Torr. For a worked example, suppose you need to convert 25 atm to torr: 25 × 760 = 19000.05 Torr. To convert in the opposite direction, divide by 760, or equivalently multiply by 0.00131579.
About atmospheres
The standard atmosphere (atm) represents the average pressure exerted by Earth's atmosphere at sea level. It was originally defined by the height of mercury in a barometer (760 mm). It is the most intuitive unit for understanding pressure: 2 atm means double the pressure you feel standing on the beach. atmospheres are commonly used in Diving depth (1 atm per 10m), Chemistry (Standard Temp/Pressure), Hyperbaric chambers, and Spacecraft engineering, Altitude simulation.
At sea level, the air pressure is exactly 1 atm.
About torr
The Torr is named after Evangelista Torricelli, the inventor of the barometer. It is defined as exactly 1/760 of a standard atmosphere. For almost all practical purposes, 1 Torr equals 1 mmHg. It is primarily used in high-vacuum physics and engineering. torr are commonly used in High vacuum systems, Mass spectrometry, Thin-film manufacturing, and Physics research.
Outer space is a near-perfect vacuum (0 Torr).
When Would You Convert atmospheres to torr?
Converting between atmospheres and torr is one of the most common pressure conversions. You might need this conversion when working with international specifications, following instructions written for a different measurement system, or comparing values across different standards. Having the conversion factor (1 atm = 760 Torr) memorized or bookmarked can save time in professional and everyday contexts alike.
