mmHg to Torr Converter
Pressure · unit-converter
Convert mmHg 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 mmHg
Millimeters of mercury (mmHg) is common in medicine (e.g. blood pressure). Here it uses the same Pa per unit as torr (133.32236842105263 Pa).
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 millimeter of mercury (mmhg) to torr
1 mmhg equals 1 torr in this tool (via pascal):
1 mmhg = (133.32236842105263 Pa ÷ 133.32236842105263 Pa) torr = 1 torr
Each mmhg carries 133.32236842105263 Pa and each torr 133.32236842105263 Pa, so one mmhg equals 133.32236842105263 ÷ 133.32236842105263 torr.
Let p(mmhg) be pressure in mmHg (mmhg), and p(torr) in Torr (torr). Then:
p(torr) = p(mmhg) × (133.32236842105263 / 133.32236842105263)
Equivalently, divide by how many mmhg fit into one torr (Pa per torr divided by Pa per mmhg):
p(torr) = p(mmhg) ÷ 1
Examples
Example #1: Convert 1 mmhg to torr
1 mmhg = 1 mmhg × (133.32236842105263/133.32236842105263) torr = 1 torr
1 mmhg = 1 mmhg ÷ 1 = 1 torr
1 mmhg × (133.32236842105263/133.32236842105263) = 1.000000 torr
Example #2: Convert 10 mmhg to torr
10 mmhg = 10 mmhg × (133.32236842105263/133.32236842105263) torr = 10 torr
10 mmhg = 10 mmhg ÷ 1 = 10 torr
10 mmhg × (133.32236842105263/133.32236842105263) = 10.000000 torr
Summary
To convert mmHg to Torr, both units use the same pascal factor (133.32236842105263 Pa per unit) in this tool, so the numeric value is unchanged (1:1).
Relationship context
You are converting between mmHg and Torr. In this tool both use the same pascal factor (standard atmosphere ÷ 760), so numeric values match one-to-one between torr and mmHg.
