What Is This Tool?
This tool allows users to convert luminance measurements from millinit (mnt), a modern low-level luminance unit, to stilb (sb), an older CGS photometric unit. It helps translate values between different measurement systems for various applications in optical research and historical photometry.
How to Use This Tool?
-
Enter the luminance value in millinit units.
-
Select millinit as the original unit and stilb as the target unit.
-
Click convert to get the corresponding value in stilb.
-
Review and use the converted value for analysis or documentation.
Key Features
-
Converts luminance values from millinit to stilb units.
-
Easy-to-use interface for quick unit translation.
-
Supports comparison of contemporary and historical luminance data.
-
Browser-based tool requiring no installation.
Examples
-
10 millinit converts to 1e-6 stilb.
-
100 millinit converts to 1e-5 stilb.
Common Use Cases
-
Describing very low luminance levels on displays and screens.
-
Interpreting and converting historical photometric data from CGS units.
-
Analyzing luminance of dimmed signage or indicator lights.
-
Researching optical properties of surfaces in older literature.
Tips & Best Practices
-
Always verify the unit symbols before converting values.
-
Use this tool when comparing modern luminance measurements with legacy data.
-
Remember that stilb values will be very small due to scale differences.
-
Be aware that stilb is uncommon in modern standards.
Limitations
-
Converted values in stilb may be extremely small and less intuitive.
-
Stilb is not an SI unit and is rarely used in current luminance measurements.
-
The large scale difference may limit practical use in many modern contexts.
Frequently Asked Questions
-
What is a millinit?
-
Millinit is a luminance unit equal to one-thousandth of a nit, measuring very low brightness levels on surfaces.
-
Why convert millinit to stilb?
-
To translate modern low-level luminance measurements into older CGS units for comparison with historical or legacy data.
-
Is stilb commonly used today?
-
No, stilb is a CGS unit rarely used in modern luminance measurement standards.
Key Terminology
-
Millinit
-
A luminance unit equal to one-thousandth of a nit, used for measuring very low luminance levels.
-
Stilb
-
A CGS photometric unit of luminance equal to 10,000 candela per square metre, used historically for bright surface luminance.
-
Luminance
-
The luminous intensity emitted or reflected from a surface per unit area in a specific direction.
