What Is This Tool?
This converter helps translate luminance values from skot, an outdated unit used for very low light levels, into lumen per square foot per steradian, a non-SI unit expressing visible light intensity per area and solid angle.
How to Use This Tool?
-
Enter the luminance value in skot that you want to convert
-
Select skot as the input unit and lumen/square foot/steradian as the output unit
-
Click convert to view the equivalent luminance in lumen/square foot/steradian
Key Features
-
Converts obsolete skot luminance values into lumen/square foot/steradian units
-
Supports conversion for very low-light luminance data from historical or legacy sources
-
Ideal for photometric data calibration and comparison with modern customary units
-
Browser-based and user-friendly interface for quick luminance unit conversion
Examples
-
5 Skot equals 0.00014786 lumen/square foot/steradian
-
10 Skot equals 0.00029572 lumen/square foot/steradian
Common Use Cases
-
Interpreting very low luminance data from old photometric studies and reports
-
Calibrating modern luminance sensors based on legacy skot measurements
-
Measuring brightness of outdoor displays and signage using U.S. customary units
-
Assessing architectural lighting glare and visual comfort with customary luminance units
Tips & Best Practices
-
Use this tool to translate historical low-light data into units commonly used in the U.S.
-
Verify the context of luminance measurements when comparing legacy skot values to modern data
-
Apply conversions primarily for scotopic (low-light) vision related scenarios
-
Confirm measurement conditions align with the low luminance levels skot was designed for
Limitations
-
Skot is an outdated, non-standard unit replaced by SI units in modern photometry
-
Conversions might have limited precision due to legacy data nature
-
Skot is specific to scotopic vision and may not reflect photopic (daylight) luminance accurately
Frequently Asked Questions
-
What is the skot unit used for?
-
Skot was used to quantify very low luminance levels in scotopic vision conditions, primarily in historical low-light studies.
-
Why convert skot to lumen/square foot/steradian?
-
Conversion helps translate legacy low-light measurements into common units used for lighting design, signage, and photometric calibration.
-
Is skot still used in modern lighting measurements?
-
No, skot is obsolete and has been replaced by SI units such as candela per square meter in current practice.
Key Terminology
-
Skot
-
An obsolete photometric unit for very low luminance levels under scotopic vision, no longer used in modern practice.
-
Lumen/Square foot/Steradian
-
A non-SI unit of luminance expressing luminous flux per unit area per unit solid angle, commonly used in U.S. customary measurements.
-
Scotopic Vision
-
The vision of the eye under low-light conditions where skot was applicable for measuring luminance.
