Pressure / Pa → Torr
Convert Pascals to Torr
Convert pressure differences or absolute pressures between consistent units. Convert Pascals (Pa) to Torr (Torr). Find the formula, worked examples, unit definitions, and practical guidance below.
How to convert pascals 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 Pa, b for the intermediate value in Pa, and y for the result in Torr.
Torr = Pa ÷ 133.32236842105263
Worked examples
10 Pa ≈ 0.0750061682704 Torr
Step 1: (10 × 1) ≈ 10 Pa.
Step 2: 10 ÷ 133.322368421 ≈ 0.0750061682704 Torr.20 Pa ≈ 0.150012336541 Torr
Step 1: (20 × 1) ≈ 20 Pa.
Step 2: 20 ÷ 133.322368421 ≈ 0.150012336541 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 Pascals
Pascals (Pa) measures pressure under the conventions above. The base value in Pa is (x × 1), where x is the numerical value in Pa. Factors shown here are rounded for display; calculations use the stored factor.
About Torr
Torr (Torr) measures pressure under the conventions above. The base value in Pa is (x × 133.322368421), where x is the numerical value in Torr. Factors shown here are rounded for display; calculations use the stored factor.
