What is the unit of mtorr?
In science and engineering, pressure units are widely used, andmtorris a common unit of pressure. This article will introduce in detail the definition of mtorr, application scenarios and conversion relationship with other pressure units, and combine it with hot topics in the past 10 days to help readers better understand this unit.
1. Definition of mtorr
mtorr is one thousandth of the pressure unit "torr", that is, 1 mtorr = 0.001 torr. Torr is named after Italian physicist Evangelista Torricelli and is used to measure low pressure in a vacuum environment. 1 torr is equal to the pressure of 1 millimeter of mercury (mmHg), so 1 mtorr = 0.001 mmHg.
2. Application scenarios of mtorr
mtorr is usually used in high vacuum or ultra-high vacuum areas, such as:
- Vacuum deposition in semiconductor manufacturing processes
- Vacuum systems in laboratories
- Space simulation environment
- Plasma research
These fields require extremely high pressure measurement accuracy, and mtorr can meet this demand.
3. Conversion between mtorr and other pressure units
The following is the conversion relationship between mtorr and other common pressure units:
| unit | Conversion relationship |
|---|---|
| 1mtorr | 0.001 torr |
| 1mtorr | 0.001mmHg |
| 1 mtorr | 0.133322Pa |
| 1 mtorr | 1.93368×10⁻⁵ psi |
4. The correlation between hot topics and pressure units in the past 10 days
In the past 10 days, many of the hot topics in the fields of science and technology and engineering have been related to vacuum technology and pressure measurement. The following are some hot topics:

5. Why is mtorr so important in scientific research?
As a unit for measuring extremely low pressure, mtorr plays an irreplaceable role in scientific research and industry. Here are a few reasons why it’s important:
-High precision requirements: Many experiments and manufacturing processes need to be performed at extremely low pressures, mtorr can provide more accurate measurements.
-Standardization: The international scientific community generally adopts mtorr as one of the standard units of vacuum pressure to facilitate data comparison and exchange.
-technology suitability: Modern vacuum pumps and pressure sensors are often designed with mtorr as the reference unit.
6. Summary
mtorr is an indispensable pressure unit in vacuum technology, especially widely used in semiconductor, space research and laboratory fields. Through conversions to other units and practical application examples, we can gain a deeper understanding of its importance. With the development of science and technology, mtorr-level pressure control will continue to promote progress in many frontier fields.
