What Is This Tool?

This converter allows users to transform luminance values expressed in lambert, a traditional CGS unit, into lumen per square centimeter per steradian, a photometric unit measuring luminous flux per area and solid angle. It is useful for bridging historical data with modern photometric analysis.

How to Use This Tool?

  • Enter the luminance value in lamberts (L).
  • Select lambert as the source unit and lumen/sq. cm/steradian as the target unit.
  • Click convert to obtain the equivalent luminance in lumen per square centimeter per steradian.
  • Interpret the result for your optical measurement or analysis needs.

Key Features

  • Converts luminance from lambert (L) to lumen/sq. cm/steradian accurately based on defined conversion rate.
  • Supports optical engineering, photographic, printing, and cinematic luminance data conversion.
  • Facilitates comparison of legacy CGS luminance data with modern SI-compatible units.
  • Browser-based and easy to use without the need for installation.

Examples

  • 2 Lambert [L] equals 0.6366197724 lumen/sq. cm/steradian using the conversion formula.
  • 0.5 Lambert [L] converts to 0.1591549431 lumen/sq. cm/steradian with this tool.

Common Use Cases

  • Converting older photometric data in lambert to modern SI-compatible luminance units for comparison.
  • Characterizing brightness in optical engineering and micro-display manufacturing.
  • Calibrating luminance meters and standards for small-area or high-intensity light sources.

Tips & Best Practices

  • Ensure input luminance values in lambert are accurate and correspond to standardized definitions.
  • Use this tool when converting legacy CGS data to avoid manual calculation errors.
  • Apply the converted results carefully in contexts requiring standardized SI luminance units.

Limitations

  • The lambert is a non-SI unit mainly used in historical or legacy contexts.
  • Conversions may be limited by rounding and precision loss during calculations.
  • Source data inconsistencies can affect conversion accuracy.

Frequently Asked Questions

What is a lambert in luminance measurement?
A lambert is a non-SI unit of luminance used for self-luminous or diffusely reflecting surfaces, defined as 1/π candela per square centimetre.

Why convert lambert to lumen/sq. cm/steradian?
Converting enables comparison of older CGS photometric data with modern SI-compatible units for accurate optical and photometric analysis.

Is lambert still commonly used today?
Lambert is largely supplanted by SI units and mainly appears in legacy data or specific historical measurement contexts.

Key Terminology

Lambert (L)
A non-SI unit of luminance equal to 1/π candela per square centimetre, used for self-luminous or diffusely reflecting surfaces.
Lumen per Square Centimeter per Steradian
A metric unit of luminance measuring luminous flux per unit area and solid angle, equivalent to candela per square centimeter.
