Convert Bar to Torr
Convert Bar to Torr for vacuum and lab contexts using the exact 750.062 factor.
How to Convert Bar to Torr
To convert Bar to Torr, multiply bar by 750.062.
Conversion Formula:
value * 750.062Understanding the Conversion
Bar to Torr bridges industrial/metric pressures to the vacuum-oriented Torr scale. Multiply bar by 750.062. For example, 1 bar ≈ 750.062 Torr, and 1.01325 bar ≈ 760 Torr (atmosphere). This is useful when bar-based specs must be interpreted for vacuum systems or lab equipment calibrated in Torr.
The conversion is reversible—divide Torr by 750.062 to return to bar.
Conversion Examples
Example: Convert 1.01325 bar to Torr
- Step 1: 1.01325 × 750.062 ≈ 760.
- Step 2: Result ≈ 760 Torr.
- Step 3: Atmospheric reference.
1.01325 bar ≈ 760 Torr
Matches 1 atm.
Example: Convert 0.5 bar to Torr
- Step 1: 0.5 × 750.062 ≈ 375.03.
- Step 2: Result ≈ 375 Torr.
- Step 3: Midrange example.
0.5 bar ≈ 375 Torr
Sub-atmospheric level.
Example: Convert 2 bar to Torr
- Step 1: 2 × 750.062 ≈ 1500.12.
- Step 2: Result ≈ 1,500 Torr.
- Step 3: Higher pressure example.
2 bar ≈ 1,500 Torr
Above atmospheric equivalent.
Conversion Formula
1 bar equals 100,000 Pa and 1 Torr equals about 133.322 Pa. Multiplying bar by 100,000/133.322 yields 750.062.

Unit Definitions
Bar (bar)
Metric-adjacent unit.
1 bar ≈ 750.062 Torr = 100 kPa ≈ 14.5038 psi.
Torr (Torr)
Vacuum unit (1/760 atm).
Torr to bar divide by 750.062; Torr to kPa divide by 7.50062; Torr to Pa multiply by 133.322.
Common Use Cases
- Vacuum systems: convert bar readings for Torr-based gauges.
- Labs: present bar measurements in Torr for experiments.
- Semiconductor/process: align bar specs to Torr recipes.
- Education: show relationship between bar and vacuum scales.
