Hectopascal to Torr Converter
Pressure · unit-converter
Convert Hectopascal 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 Hectopascal
The hectopascal (hPa) equals 100 Pa. Meteorologists use hPa for surface charts; 1 hPa equals 1 millibar.
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 hectopascal (hpa) to torr
1 hectopascal equals 0.7500616827041697 torr in this tool (via pascal):
1 hpa = (100 Pa ÷ 133.32236842105263 Pa) torr = 0.7500616827041697 torr
Each hectopascal carries 100 Pa and each torr 133.32236842105263 Pa, so one hpa equals 100 ÷ 133.32236842105263 torr.
Let p(hpa) be pressure in Hectopascal (hpa), and p(torr) in Torr (torr). Then:
p(torr) = p(hpa) × (100 / 133.32236842105263)
Equivalently, divide by how many hpa fit into one torr (Pa per torr divided by Pa per hpa):
p(torr) = p(hpa) ÷ 1.3332236842105263
Examples
Example #1: Convert 1 hpa to torr
1 hpa = 1 hpa × (100/133.32236842105263) torr = 0.7500616827 torr
1 hpa = 1 hpa ÷ 1.3332236842105263 = 0.7500616827 torr
1 hpa × (100/133.32236842105263) = 0.750062 torr
Example #2: Convert 10 hpa to torr
10 hpa = 10 hpa × (100/133.32236842105263) torr = 7.500616827 torr
10 hpa = 10 hpa ÷ 1.3332236842105263 = 7.500616827 torr
10 hpa × (100/133.32236842105263) = 7.500617 torr
Summary
To convert Hectopascal to Torr, multiply the value in hpa by (100 Pa per hpa) / (133.32236842105263 Pa per torr). Equivalently: value_torr = value_hpa × (100 / 133.32236842105263). Numerically, 1 hpa equals 0.7500616827041697 torr.
Relationship context
Both Hectopascal and Torr are converted by fixed multiples of the pascal. Multiplying by (Pa per hpa) ÷ (Pa per torr) gives the same result as passing through pascal, keeping bar, atm, PSI, kPa, hPa, torr, and mmHg consistent on the hub.
