What Is This Tool?
This tool allows users to convert luminance values expressed in Skot, an outdated unit for very low light levels, into Foot-lambert (fL), an imperial unit commonly applied in display and projection brightness measurements.
How to Use This Tool?
-
Enter the luminance value in Skot you want to convert
-
Select Skot as the input unit and Foot-lambert [fL] as the output unit
-
Click convert to see the equivalent luminance in Foot-lambert
Key Features
-
Converts very low luminance levels from Skot to Foot-lambert [fL]
-
Supports conversion relevant to legacy and modern luminance comparisons
-
Browser-based and easy to use for lighting and vision study applications
Examples
-
10 Skot converts to 0.00092903 Foot-lambert [fL]
-
100 Skot converts to 0.0092903 Foot-lambert [fL]
Common Use Cases
-
Interpreting low-light luminance data from historical photometry
-
Converting legacy scotopic vision measurements for modern sensor calibration
-
Specifying brightness levels in cinema and home theater projection using Foot-lambert units
Tips & Best Practices
-
Use this conversion mainly for evaluating and comparing historical luminance data
-
Ensure careful handling due to the very low conversion factor from Skot to Foot-lambert
-
Reference modern SI luminance units for precise and current measurements
Limitations
-
Skot is an obsolete, non-SI unit rarely applied today
-
Conversions mainly serve to interpret legacy data rather than current measurements
-
Modern instrumentation typically uses SI luminance units rather than Skot
Frequently Asked Questions
-
What is the Skot unit used for?
-
Skot was used to measure very low luminance levels under scotopic (dark-adapted) vision, primarily in older lighting and vision studies.
-
Why convert Skot to Foot-lambert?
-
Converting Skot to Foot-lambert helps compare legacy low-light measurements with modern brightness specifications in cinema, display, and projection technologies.
-
Is Skot commonly used today?
-
No, Skot is obsolete and has been replaced by SI units like candela per square meter for luminance measurements.
Key Terminology
-
Skot
-
An obsolete photometric unit for very low luminance levels under scotopic vision, no longer used in modern practice.
-
Foot-lambert [fL]
-
An imperial unit of luminance measuring luminous intensity per projected area, used in display and projection brightness.
-
Luminance
-
A photometric measure of the luminous intensity emitted or reflected from a surface per unit area in a given direction.
