Exact RatioAbout Standard Atmosphere (atm)
An internationally agreed reference pressure defined as exactly 101,325 pascals (1.01325 bar).
History: Originally established as the pressure exerted by 760 mm of mercury at sea level and 0 ยฐC.
Common Uses: Chemical thermodynamics, underwater diving depths (1 atm per 10m depth), and gas cylinders.
About Torr (Torr)
A unit of pressure defined as exactly 1/760 of a standard atmosphere (โ 133.3223684 Pa).
History: Named in honor of Evangelista Torricelli, Italian physicist who invented the barometer in 1643.
Common Uses: High-vacuum physics, blood pressure measurements, and freeze-drying equipment.
โ Frequently Asked Questions
How many Torr are in 1 Standard Atmosphere?
There are exactly 760 Torr in 1 Standard Atmosphere (1 atm = 760 Torr).
What is the formula to convert Standard Atmosphere to Torr?
The formula is: Torr = Standard Atmosphere ร 760. Since 1 Standard Atmosphere = 760 Torr, multiply the value in Standard Atmospheres by 760.
How do I convert 1 atm to Torr manually?
To convert 1 atm to Torr: apply the formula Torr = Standard Atmosphere ร 760. Substituting gives: 1 ร 760 = 760 Torr.
