How to convert standard atmospheres to torr
This changes units only. Gauge and absolute pressures need a known ambient pressure to relate them; the converter does not add atmospheric pressure.
Use x for the value in atm, b for the intermediate value in Pa, and y for the result in Torr.
Torr = atm × 101325 ÷ 133.32236842105263
Worked examples
10 atm ≈ 7600 Torr
Step 1: (10 × 101325) ≈ 1013250 Pa.
Step 2: 1013250 ÷ 133.322368421 ≈ 7600 Torr.20 atm ≈ 15200 Torr
Step 1: (20 × 101325) ≈ 2026500 Pa.
Step 2: 2026500 ÷ 133.322368421 ≈ 15200 Torr.
Results are rounded to 12 significant digits. Converting units does not increase the precision of the original measurement. Very large or small values outside JavaScript’s finite numeric range are rejected.
About Standard atmospheres
Standard atmospheres (atm) measures pressure under the conventions above. The base value in Pa is (x × 101325), where x is the numerical value in atm. Factors shown here are rounded for display; calculations use the stored factor.
About Torr
