Torr to Hectopascal Converter
Pressure · unit-converter
Convert Torr to Hectopascal 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 Torr
The torr is defined as 1/760 of a standard atmosphere (≈133.32236842105263 Pa). It is widely used in vacuum science alongside pascal.
About Hectopascal
The hectopascal (hPa) equals 100 Pa. Meteorologists use hPa for surface charts; 1 hPa equals 1 millibar.
How to convert torr to hectopascal (hpa)
1 torr equals 1.3332236842105263 hectopascal in this tool (via pascal):
1 torr = (133.32236842105263 Pa ÷ 100 Pa) hpa = 1.3332236842105263 hpa
Each torr carries 133.32236842105263 Pa and each hectopascal 100 Pa, so one torr equals 133.32236842105263 ÷ 100 hpa.
Let p(torr) be pressure in Torr (torr), and p(hpa) in Hectopascal (hpa). Then:
p(hpa) = p(torr) × (133.32236842105263 / 100)
Equivalently, divide by how many torr fit into one hpa (Pa per hpa divided by Pa per torr):
p(hpa) = p(torr) ÷ 0.7500616827041697
Examples
Example #1: Convert 1 torr to hectopascal
1 torr = 1 torr × (133.32236842105263/100) hpa = 1.3332236842 hpa
1 torr = 1 torr ÷ 0.7500616827041697 = 1.3332236842 hpa
1 torr × (133.32236842105263/100) = 1.333224 hpa
Example #2: Convert 10 torr to hectopascal
10 torr = 10 torr × (133.32236842105263/100) hpa = 13.3322368421 hpa
10 torr = 10 torr ÷ 0.7500616827041697 = 13.3322368421 hpa
10 torr × (133.32236842105263/100) = 13.332237 hpa
Summary
To convert Torr to Hectopascal, multiply the value in torr by (133.32236842105263 Pa per torr) / (100 Pa per hpa). Equivalently: value_hpa = value_torr × (133.32236842105263 / 100). Numerically, 1 torr equals 1.3332236842105263 hpa.
Relationship context
Both Torr and Hectopascal are converted by fixed multiples of the pascal. Multiplying by (Pa per torr) ÷ (Pa per hpa) gives the same result as passing through pascal, keeping bar, atm, PSI, kPa, hPa, torr, and mmHg consistent on the hub.
