Atmosphere to Torr Converter
Pressure · unit-converter
Convert Atmosphere to Torr with a fixed input and output unit, step-by-step formula line, and reference tables. All calculations bridge through pascal with fixed definitions (standard atmosphere = 101,325 Pa; torr and mmHg = atm/760; plus industrial/manometer units like kgf/cm², inHg, inH2O, and mmH2O).
About Atmosphere
The standard atmosphere (atm) is defined as exactly 101,325 Pa. It links legacy chemistry and physics problems to SI.
About Torr
The torr is defined as 1/760 of a standard atmosphere (≈133.32236842105263 Pa). It is widely used in vacuum science alongside pascal.
How to convert atmosphere to torr
1 atmosphere equals 760 torr in this tool (via pascal):
1 atm = (101325 Pa ÷ 133.32236842105263 Pa) torr = 760 torr
Each atmosphere carries 101325 Pa and each torr 133.32236842105263 Pa, so one atm equals 101325 ÷ 133.32236842105263 torr.
Let p(atm) be pressure in Atmosphere (atm), and p(torr) in Torr (torr). Then:
p(torr) = p(atm) × (101325 / 133.32236842105263)
Equivalently, divide by how many atm fit into one torr (Pa per torr divided by Pa per atm):
p(torr) = p(atm) ÷ 0.0013157894736842105
Examples
Example #1: Convert 1 atm to torr
1 atm = 1 atm × (101325/133.32236842105263) torr = 760 torr
1 atm = 1 atm ÷ 0.0013157894736842105 = 760 torr
1 atm × (101,325/133.32236842105263) = 760.000000 torr
Example #2: Convert 10 atm to torr
10 atm = 10 atm × (101325/133.32236842105263) torr = 7600 torr
10 atm = 10 atm ÷ 0.0013157894736842105 = 7600 torr
10 atm × (101,325/133.32236842105263) = 7,600.000000 torr
Summary
To convert Atmosphere to Torr, multiply the value in atm by (101325 Pa per atm) / (133.32236842105263 Pa per torr). Equivalently: value_torr = value_atm × (101325 / 133.32236842105263). Numerically, 1 atm equals 760 torr.
Relationship context
Both Atmosphere and Torr are converted by fixed multiples of the pascal. Multiplying by (Pa per atm) ÷ (Pa per torr) gives the same result as passing through pascal, keeping bar, atm, PSI, kPa, hPa, torr, and mmHg consistent on the hub.
