What Is This Tool?

This converter facilitates transforming luminance measurements from stilb (sb) to foot-lambert (fL). Stilb is a CGS unit representing luminous intensity per area, while foot-lambert is an imperial unit used commonly for display brightness and projection system evaluations.

How to Use This Tool?

  • Enter the luminance value in stilb (sb)
  • Select stilb as the starting unit and foot-lambert (fL) as the target unit
  • Click convert to get the equivalent value in foot-lambert
  • Interpret the results for use in display calibration or optical research

Key Features

  • Converts luminance units from stilb (CGS system) to foot-lambert (imperial system)
  • Supports interpretation of historical photometric data in modern contexts
  • Useful for cinema, home theater, and projection screen brightness calibration
  • Facilitates comparison between legacy and contemporary luminance measurements

Examples

  • 0.5 Stilb equals approximately 1459.3175 Foot-lambert
  • 2 Stilb corresponds to about 5837.2702 Foot-lambert

Common Use Cases

  • Converting historical CGS luminance data to imperial units for modern comparison
  • Calibrating projected screen brightness in cinemas and home theaters
  • Assessing reflected luminance in projection system design and testing
  • Reviewing legacy scientific publications and optical instrumentation specifications

Tips & Best Practices

  • Ensure luminance values are accurately entered in stilb before conversion
  • Use the conversion for interpreting older data rather than for real-time measurements
  • Consider further conversions if consistent SI units are required
  • Validate results when applying converted values in projection or display calibration

Limitations

  • Stilb is rarely used in current measurements and mostly relevant for legacy data
  • Foot-lambert is specific to imperial measurement systems, limiting SI compatibility
  • Measurement conditions such as projected area and reflectance may affect conversion accuracy

Frequently Asked Questions

What is stilb used for?
Stilb is a photometric luminance unit from the CGS system, often used for historical data and optical research.

Why convert stilb to foot-lambert?
Converting helps compare and interpret luminance values from older CGS units to imperial units prevalent in display and projection industries.

Is foot-lambert compatible with SI units?
Foot-lambert is an imperial unit and may require additional conversion for consistency within SI measurement frameworks.

Key Terminology

Stilb (sb)
A CGS photometric unit of luminance equal to 10,000 candela per square meter, used for describing luminous intensity from surfaces.
Foot-lambert (fL)
An imperial luminance unit representing luminous intensity per projected area, commonly used in cinema and projection screen brightness.
Luminance
A photometric measure of the luminous intensity emitted or reflected from a surface per unit area in a specific direction.
