What Is This Tool?

This converter transforms luminance measurements from the Stilb (sb), an older CGS unit, into Candela per square meter (cd/m²), the modern SI unit. It helps interpret and compare luminance data reported in different unit systems.

How to Use This Tool?

  • Enter the luminance value in Stilb (sb) that you want to convert.
  • Select Stilb as the from-unit and Candela per square meter as the to-unit.
  • Click the convert button to get the equivalent luminance in Candela per square meter.

Key Features

  • Accurate conversion between Stilb and Candela per square meter using established conversion rates.
  • Supports translation of historical photometric data into contemporary SI units.
  • Useful for optical research, display calibration, and lighting design applications.
  • Browser-based and easy to use for quick luminance value conversions.

Examples

  • 0.5 Stilb equals 5000 Candela per square meter (0.5 × 10000 cd/m²).
  • 2 Stilb equals 20000 Candela per square meter (2 × 10000 cd/m²).

Common Use Cases

  • Translating luminance data from older publications reported in Stilb to modern SI units.
  • Comparing historical photometric measurements with current display and lighting standards.
  • Assisting research efforts where legacy luminance values need integration with modern instrumentation.

Tips & Best Practices

  • Verify units carefully to ensure correct input and output for conversion accuracy.
  • Use the tool to cross-reference luminance values when working with both historical and current data.
  • Be aware of measurement context and calibration differences between older and modern instruments.

Limitations

  • Stilb is a CGS unit rarely used in current standards, requiring precise conversion steps.
  • Measurement accuracy can be influenced by calibration variations of equipment across different eras.
  • Conversion assumes a uniform luminance surface and consistent observation direction.

Frequently Asked Questions

What is a Stilb (sb)?
The Stilb (sb) is a CGS unit of luminance representing 10,000 candela per square meter, measuring luminous intensity emitted or reflected from surfaces.

Why convert Stilb to Candela per square meter?
Converting Stilb to Candela per square meter helps interpret historic photometric data in the modern SI unit system for accurate comparison and analysis.

Is the Stilb commonly used today?
No, Stilb is an older CGS unit not commonly used currently; modern measurements typically use Candela per square meter.

Key Terminology

Stilb (sb)
A CGS photometric unit of luminance equal to 10,000 candela per square meter, representing luminous intensity per unit area in a given direction.
Candela per square meter (cd/m²)
The SI unit of luminance that quantifies how bright a surface is perceived based on light emitted or reflected per unit area.
Luminance
The measure of luminous intensity emitted or reflected by a surface per unit projected area in a specified direction.
