What Is This Tool?

This converter helps translate luminance values from the stilb unit, used historically in CGS photometric measurements, into kilocandela per square meter, a modern SI-based unit widely applied in display technology and brightness specification.

How to Use This Tool?

  • Enter the luminance value in stilb (sb) into the input field.
  • Select stilb as the input unit and kilocandela per square meter as the output unit.
  • Click the convert button to get the equivalent luminance value in kilocandela per square meter.
  • Review the result to compare historical CGS data with modern SI luminance measurements.

Key Features

  • Converts luminance from stilb (sb) to kilocandela per square meter (kcd/m²).
  • Supports interpretation and comparison of historical and modern luminance data.
  • Includes conversion formula with a fixed rate of 1 stilb equals 10 kilocandela per square meter.
  • Useful for applications in display engineering, automotive HUDs, and outdoor signage.
  • Browser-based and easy to use without installation.

Examples

  • 2 stilb equals 20 kilocandela per square meter.
  • 0.5 stilb equals 5 kilocandela per square meter.

Common Use Cases

  • Translating old photometric data in stilb into modern SI units for scientific research.
  • Evaluating and comparing brightness levels in HDR displays and television screens.
  • Setting luminance standards for automotive heads-up displays and instrument panels.
  • Calibrating brightness for outdoor LED billboards and digital signage.

Tips & Best Practices

  • Ensure you understand the difference between CGS and SI unit systems when converting.
  • Use this tool to compare and interpret luminance values in legacy and modern contexts.
  • Verify that the measurement conditions correspond to uniform surface luminance for accurate conversion.
  • Apply the conversion carefully in cases where angular or spectral variations might affect luminance.

Limitations

  • Stilb is based on CGS units and differs by a factor of 10 from kilocandelas per square meter.
  • The conversion assumes uniform luminance across the surface measured.
  • It may not capture variations due to viewing angles or spectral characteristics relevant in precise photometric scenarios.

Frequently Asked Questions
