What Is This Tool?
This converter transforms luminance measurements from millinit, a modern unit for very low brightness levels, into blondel, an older photometric unit used historically. It supports understanding and comparing luminance in different contexts, including legacy data.
How to Use This Tool?
-
Enter the luminance value measured in millinit (mnt)
-
Select the input unit as millinit and the output unit as blondel
-
Click the convert button to see the equivalent value in blondel
-
Use the converted values to compare or interpret luminance in historical contexts
Key Features
-
Converts luminance values from millinit to the obsolete blondel unit
-
Supports analysis of low-brightness display and signage luminance
-
Facilitates comparison of contemporary measurements with historical data
-
Browser-based and easy to use without installation
Examples
-
10 millinit equals approximately 0.031415927 blondel
-
100 millinit converts to about 0.31415927 blondel
Common Use Cases
-
Describing very low luminance levels of displays or screens such as night modes
-
Specifying luminance for low-brightness instrument panels or indicator lights
-
Reconciling contemporary luminance data with early 20th-century photometry reports
-
Converting historical photometric measurements to modern units for analysis
Tips & Best Practices
-
Ensure accurate input of millinit values for reliable conversion results
-
Use converted blondel values to contextualize legacy luminance documentation
-
Refer to the exact measurement contexts when comparing historical and modern data
-
Remember the blondel is outdated and mainly of historical interest
Limitations
-
Blondel is an obsolete unit rarely used today, so conversion mainly supports historical comparison
-
Accuracy relies on correct original measurement conditions and definitions
-
Older data may involve approximations, affecting precision of conversions
Frequently Asked Questions
-
What is millinit used for?
-
Millinit measures very low luminance, such as dimmed displays or low-brightness panels, representing one-thousandth of a nit.
-
Why convert millinit to blondel?
-
Converting helps compare modern low luminance readings with older photometric data recorded in blondel, aiding historical research and data reconciliation.
-
Is blondel still commonly used?
-
No, blondel is an outdated unit replaced by candela per square metre; conversions serve mainly historical or comparative purposes.
Key Terminology
-
Millinit [mnt]
-
A luminance unit equal to one-thousandth of a nit, used for very low brightness levels.
-
Blondel
-
An obsolete photometric luminance unit named after André Blondel, replaced by candela per square metre.
-
Luminance
-
The measure of luminous intensity emitted or reflected from a surface per unit area.
