What Is This Tool?
This tool allows you to convert pressure measurements from microbar (µbar), a unit used to express very small pressures mainly in vacuum and atmospheric research, to dyne per square centimeter (dyne/cm²), a CGS unit commonly used in legacy physics and scientific literature.
How to Use This Tool?
-
Enter the pressure value in microbar (µbar) that you want to convert
-
Select microbar as the input unit and dyne per square centimeter as the output unit
-
Click the convert button to receive the equivalent pressure in dyne/cm²
-
Use the result to compare or analyze pressure values across SI and CGS measurement systems
Key Features
-
Convert pressure values from microbar to dyne per square centimeter instantly
-
Supports pressure units relevant to vacuum, atmospheric, and scientific measurement
-
Browser-based and easy to use with a straightforward interface
-
Helps correlate modern SI-based measurements with historical CGS system units
-
Facilitates data comparison in various scientific disciplines such as astrophysics and plasma physics
Examples
-
5 microbar [µbar] equals 5 dyne/square centimeter
-
0.1 microbar [µbar] equals 0.1 dyne/square centimeter
Common Use Cases
-
Characterizing low pressures in laboratory vacuum systems such as electron microscopy preparation
-
Measuring subtle acoustic or atmospheric pressure fluctuations in geophysical research
-
Specifying residual gas pressures in space simulation and aerospace testing environments
-
Expressing small pressures or mechanical stresses in legacy CGS-unit-based physics research
-
Converting historical pressure data between SI and CGS units in astrophysics or materials science
Tips & Best Practices
-
Ensure unit systems are correctly identified when comparing data across scientific fields
-
Use this conversion for small pressures relevant to vacuum and atmospheric studies
-
Be cautious when integrating data with other pressure units from different measurement systems
-
Consider the context of measurements as equivalence assumes ideal conditions without environmental adjustments
Limitations
-
Microbar and dyne per square centimeter originate from different unit systems (SI vs CGS)
-
Conversion equivalence assumes ideal conditions and does not account for temperature or medium effects
-
Care is needed when combining these units with data expressed in other pressure measurement units
Frequently Asked Questions
-
What is the relationship between microbar and dyne per square centimeter?
-
One microbar is equal to one dyne per square centimeter, making conversion straightforward for small pressure values.
-
In which fields is converting microbar to dyne/cm² commonly used?
-
This conversion is applied in vacuum science, atmospheric research, astrophysics, plasma physics, and materials science, especially when relating SI-based data to legacy CGS units.
-
Are there any limitations when converting between these two units?
-
Yes, since microbar and dyne/cm² come from different measurement systems, results assume ideal conditions and don't account for environmental factors like temperature, so caution is advised.
Key Terminology
-
Microbar [µbar]
-

-
Dyne per square centimeter (dyne/cm²)
-
A CGS unit of pressure equal to one dyne applied over one square centimeter, also known as barye, equivalent to 0.1 pascal.
-
CGS System
-
A unit system based on centimeters, grams, and seconds, historically used in scientific research and engineering.
