Torr to MBAR Converter: Convert Torr to Millibar Easily
This tool converts pressure from torr to millibar (mbar) quickly and accurately—perfect for vacuum technology, physics labs, and meteorological data.
Understanding the Conversion from Torr to Millibar (mbar)
In scientific research and engineering, accurate pressure measurement is crucial. While torr is a traditional pressure unit widely used in vacuum systems and laboratories, millibar (mbar) is a metric unit more common in meteorology and aviation. Converting between these two units ensures compatibility across instruments, datasets, and international standards.
What Is a Torr?
The torr is a non-SI unit of pressure defined as exactly 1/760 of one atmosphere. One torr is approximately equal to 133.322 pascals. It is named after Evangelista Torricelli, the inventor of the barometer. Torr is commonly used in vacuum physics, plasma research, and systems requiring fine pressure control.
What Is a Millibar (mbar)?
The millibar is a metric unit of pressure equal to 100 pascals. It is not part of the SI system but is widely accepted, particularly in meteorology. Standard atmospheric pressure at sea level is approximately 1013.25 mbar. The unit is used in weather forecasts, aviation altimeters, and climate science.
Conversion Formula
mbar = torr × 1.33322
Example: 760 torr × 1.33322 = 1013.25 mbarTorr to MBAR Conversion Table
| Torr | Millibar (mbar) |
|---|---|
| 1 | 1.33 |
| 10 | 13.33 |
| 100 | 133.32 |
| 200 | 266.64 |
| 500 | 666.61 |

Why Convert Torr to Millibar?
- Vacuum Measurement: Torr is often used for low-pressure systems, but modern sensors may use mbar.
- Meteorology and Aviation: Systems reporting in mbar require conversion from legacy torr readings.
- Scientific Publications: Journals may request SI-compatible units such as mbar for clarity.
- Global Standardization: mbar allows easier comparison and integration with metric-based equipment.
