What Is This Tool?

This converter transforms luminance measurements from stilb, a CGS unit representing high brightness levels, to skot, an outdated unit used for very low luminance under dark-adapted vision conditions. It helps bridge historical photometric data with different illumination regimes.

How to Use This Tool?

  • Enter the luminance value in stilb (sb) that you want to convert.
  • Select stilb as the source unit and skot as the target unit.
  • Click the convert button to see the equivalent luminance in skot.
  • Use the results to compare or analyze photometric data across lighting conditions.

Key Features

  • Converts luminance values between stilb and skot units quickly and accurately.
  • Supports interpretation of legacy photometric data for research and calibration.
  • Browser-based interface without the need for additional software.
  • Handles large conversion factors between bright and very low luminance levels.

Examples

  • 2 Stilb [sb] = 62831853.07 Skot
  • 0.5 Stilb [sb] = 15707963.27 Skot

Common Use Cases

  • Translating historical photometric values from high to very low luminance units.
  • Analyzing legacy photometry related to bright laboratory light sources and dark-adapted vision.
  • Calibrating modern sensors and comparing with older lighting and vision study data.
  • Interpreting brightness levels in older scientific and engineering literature.

Tips & Best Practices

  • Always verify unit context before conversion due to fundamental differences in luminance regimes.
  • Use this tool to assist with historical data interpretation rather than modern photometric design.
  • Utilize computational support when handling very large numerical conversion results.
  • Consider the intended lighting condition—bright vs. scotopic—when comparing converted values.

Limitations

  • The skot unit is obsolete and not applicable to current photometric standards.
  • Conversion results can involve very large numbers that are unwieldy without software assistance.
  • Directly comparing values may be misleading because the units apply to quite different brightness conditions.

Frequently Asked Questions

What are stilb and skot units used for?
Stilb is a CGS unit used for high luminance such as bright surfaces, while skot was used historically for very low luminance levels in dark-adapted vision.

Is skot still used in modern photometry?
No, skot is considered an obsolete unit and has been replaced by SI luminance units like candela per square meter.

Why is the conversion factor so large between stilb and skot?
Because stilb measures much brighter luminance levels while skot is for extremely low luminance, their scales differ greatly, resulting in a large numeric conversion factor.

Key Terminology

Stilb (sb)
A CGS photometric unit of luminance equal to 10,000 candela per square metre, used to measure bright light sources or reflecting surfaces.
Skot
An obsolete photometric unit formerly used to describe very low luminance levels under dark-adapted vision conditions.
Luminance
The measure of luminous intensity emitted or reflected from a surface per unit area in a specific direction.
