Frequently asked questions

How do you convert bar to torr?

To convert bar to torr, multiply the pressure in bar by 750.061683.
Formula: torr = bar × 750.061683

What is 1 bar in torr?

1 bar = 750.061683 torr.
This value comes from standard pressure definitions used in science and engineering.

What is 1 torr in bar?

1 torr = 0.001333223684 bar (about 0.001333 bar).
Formula: bar = torr × 0.001333223684

Why is the bar to torr conversion factor 750.061683?

A bar is defined as 100,000 pascals (Pa). A torr is defined as 1/760 of standard atmosphere, which equals about 133.3223684 Pa. Dividing 100,000 Pa by 133.3223684 Pa gives 750.061683 torr per bar.

Is torr the same as mmHg?

They are close, but not always the same.

Torr is based on a defined fraction of an atmosphere.
mmHg can depend on how it’s defined and measured.
In many lab settings, people treat torr and mmHg as equal for quick work.

When should I use bar vs torr?

Use bar in many engineering and weather pressure settings.
Use torr for vacuum pressure, lab work, and many older specs for pumps and chambers.
Always match the unit used in your gauge or data sheet.

How do I convert bar to torr by hand?

Use the multiplier and keep track of decimals.
Example: 0.2 bar × 750.061683 = 150.0123366 torr
Round based on the precision you need.

How do you convert torr to bar by hand?

Multiply torr by 0.001333223684.
Example: 500 torr × 0.001333223684 = 0.666611842 bar (about 0.6666 bar)

What is the difference between absolute pressure and gauge pressure in bar to torr conversions?

The math is the same, but the meaning changes.

Absolute pressure is measured from a perfect vacuum.
Gauge pressure is measured from local air pressure.
Don’t mix gauge and absolute values when converting bar to torr.

How many torr are in 2 bar?

Multiply by 750.061683:
2 bar = 2 × 750.061683 = 1500.123366 torr
This is often rounded to 1500.12 torr.

How many torr are in 0.001 bar?

0.001 bar = 0.001 × 750.061683 = 0.750061683 torr
That’s about 0.7501 torr.

How do I round bar to torr results?

Round based on your input and your use case.

For lab notes, 2 to 4 decimal places is common.
For rough vacuum ranges, 1 to 2 decimals often works.
Try to keep about the same number of meaningful digits as your starting value.

What are common pressure benchmarks in torr and bar?

A few quick reference points:

1 bar = 750.061683 torr
1 atm = 760 torr = 1.01325 bar (approx)
0.001 bar = 0.750061683 torr
These help when checking if a conversion looks right.
