To convert torr to bar, use this fixed pressure relationship:
Formula (torr to bar):
bar = torr × 0.001333223684
Quick steps:
Example:
500 torr × 0.001333223684 = 0.666611842 bar (about 0.6666 bar)
For a quick reverse check:
torr = bar × 750.061683
A torr is a unit of pressure. It’s based on the pressure from a 1 mm column of mercury. Torr is common in vacuum work and lab settings.
A bar is a metric unit of pressure. It’s widely used in engineering, weather work, and industrial systems. One bar is close to normal air pressure at sea level.

They are very close, but not always treated as the same.
There are 750.061683 torr in 1 bar.
Since 760 torr equals 1 standard atmosphere, it converts to:
One torr equals:
Many vacuum gauges show pressure in torr. Many specs and pump ratings use bar or mbar. Converting helps you match gauge readings to equipment limits and process targets.
Here are a few quick values:
A millibar is one-thousandth of a bar:
No. Torr to bar is a unit conversion, so it doesn’t change with temperature. Temperature only affects pressure in a real system, not the math between units.
The Calculate Box tool to convert torrs to bars uses the open source script Convert.js to convert units of measurement. To use this tool, simply type a torrs value in the box and have it instantly converted to bars.
