Torr to Bar Converter
Pressure · unit-converter
Convert Torr to Bar 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 Bar
The bar is 100,000 Pa. It is convenient for industrial and approximate atmospheric pressures (1 bar ≈ 1 atm).
How to convert torr to bar
1 torr equals 0.0013332236842105263 bar in this tool (via pascal):
1 torr = (133.32236842105263 Pa ÷ 100000 Pa) bar = 0.0013332236842105263 bar
Each torr carries 133.32236842105263 Pa and each bar 100000 Pa, so one torr equals 133.32236842105263 ÷ 100000 bar.
Let p(torr) be pressure in Torr (torr), and p(bar) in Bar (bar). Then:
p(bar) = p(torr) × (133.32236842105263 / 100000)
Equivalently, divide by how many torr fit into one bar (Pa per bar divided by Pa per torr):
p(bar) = p(torr) ÷ 750.0616827041698
Examples
Example #1: Convert 1 torr to bar
1 torr = 1 torr × (133.32236842105263/100000) bar = 0.0013332237 bar
1 torr = 1 torr ÷ 750.0616827041698 = 0.0013332237 bar
1 torr × (133.32236842105263/100,000) = 0.001333 bar
Example #2: Convert 10 torr to bar
10 torr = 10 torr × (133.32236842105263/100000) bar = 0.0133322368 bar
10 torr = 10 torr ÷ 750.0616827041698 = 0.0133322368 bar
10 torr × (133.32236842105263/100,000) = 0.013332 bar
Summary
To convert Torr to Bar, multiply the value in torr by (133.32236842105263 Pa per torr) / (100000 Pa per bar). Equivalently: value_bar = value_torr × (133.32236842105263 / 100000). Numerically, 1 torr equals 0.0013332236842105263 bar.
Relationship context
Both Torr and Bar are converted by fixed multiples of the pascal. Multiplying by (Pa per torr) ÷ (Pa per bar) gives the same result as passing through pascal, keeping bar, atm, PSI, kPa, hPa, torr, and mmHg consistent on the hub.
