What Is This Tool?

This tool allows you to convert luminance measurements from stilb (sb), a CGS photometric unit, into candela per square foot, an imperial unit used to express luminous intensity per unit area.

How to Use This Tool?

  • Enter the luminance value in stilb (sb) that you want to convert.
  • Select stilb as the input unit and candela per square foot as the output unit.
  • Click the convert button to get the equivalent luminance value in candela per square foot.
  • Use the result for lighting specification, research, or display calibration needs.

Key Features

  • Converts luminance values between stilb and candela per square foot accurately using the defined conversion rate.
  • Supports usage scenarios in optical research, lighting design, and display brightness calibration.
  • Browser-based and easy to use with clear input and output formats.
  • Useful for translating historical photometric data into practical units for modern applications.

Examples

  • 2 stilb (sb) equals approximately 1858.06 candela per square foot.
  • 0.5 stilb (sb) converts to about 464.52 candela per square foot.

Common Use Cases

  • Converting historical or legacy luminance data reported in CGS units into imperial units.
  • Specifying and verifying display screen brightness where area is measured in square feet.
  • Calibrating projection screen luminance in cinema and theater environments.
  • Lighting design and signage assessments following imperial measurement standards.

Tips & Best Practices

  • Ensure you understand the context of units to maintain conversion accuracy.
  • Use this conversion when working between legacy CGS data and modern imperial measurement applications.
  • Double-check results when applying them in international or SI unit standard contexts.
  • Be aware that stilb is less common today and candela per square foot is a non-SI unit.

Limitations

  • Stilb is a CGS unit and not widely used in contemporary photometric measurements.
  • Candela per square foot is a non-SI unit and may require additional conversion for international standards.
  • Conversion accuracy depends on the precise context and understanding of unit applications.

Frequently Asked Questions

What is stilb (sb) used for?
Stilb is a CGS unit of luminance used historically in optical research and older literature to describe surface brightness.

Why convert stilb to candela per square foot?
Converting stilb to candela per square foot helps translate older CGS measurements into practical imperial units used in lighting, display, and projection calibrations.

Is candela per square foot an SI unit?
No, candela per square foot is a non-SI (imperial) unit commonly used where area is measured in square feet.

Key Terminology

Stilb (sb)
A CGS photometric unit of luminance equal to 10,000 candela per square meter, representing brightness emitted or reflected from a surface.
Candela per square foot
A non-SI unit of luminance expressing luminous intensity per square foot area, used often in lighting and display measurements within imperial systems.
