Pascal to Torr Converter
Pressure · unit-converter
Convert Pascal 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 Pascal
The pascal (Pa) is the SI unit of pressure (one newton per square meter). It is the common reference for scientific and engineering work.
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 pascal to torr
1 pascal equals 0.007500616827041697 torr in this tool (via pascal):
1 pa = (1 Pa ÷ 133.32236842105263 Pa) torr = 0.007500616827041697 torr
Each pascal carries 1 Pa and each torr 133.32236842105263 Pa, so one pa equals 1 ÷ 133.32236842105263 torr.
Let p(pa) be pressure in Pascal (pa), and p(torr) in Torr (torr). Then:
p(torr) = p(pa) × (1 / 133.32236842105263)
Equivalently, divide by how many pa fit into one torr (Pa per torr divided by Pa per pa):
p(torr) = p(pa) ÷ 133.32236842105263
Examples
Example #1: Convert 1 pa to torr
1 pa = 1 pa × (1/133.32236842105263) torr = 0.0075006168 torr
1 pa = 1 pa ÷ 133.32236842105263 = 0.0075006168 torr
1 pa × (1/133.32236842105263) = 0.007501 torr
Example #2: Convert 10 pa to torr
10 pa = 10 pa × (1/133.32236842105263) torr = 0.0750061683 torr
10 pa = 10 pa ÷ 133.32236842105263 = 0.0750061683 torr
10 pa × (1/133.32236842105263) = 0.075006 torr
Summary
To convert Pascal to Torr, multiply the value in pa by (1 Pa per pa) / (133.32236842105263 Pa per torr). Equivalently: value_torr = value_pa × (1 / 133.32236842105263). Numerically, 1 pa equals 0.007500616827041697 torr.
Relationship context
Both Pascal and Torr are converted by fixed multiples of the pascal. Multiplying by (Pa per pa) ÷ (Pa per torr) gives the same result as passing through pascal, keeping bar, atm, PSI, kPa, hPa, torr, and mmHg consistent on the hub.
