What Is This Tool?

This converter enables users to change luminance values from lambert, a CGS unit for self-luminous or diffusely reflecting surfaces, into stilb, another CGS unit describing luminous intensity per surface area. It supports interpreting and comparing older photometric data within classical units.

How to Use This Tool?

  • Enter the luminance value in lambert [L].
  • Choose lambert as the input unit and stilb as the output unit.
  • Click the convert button to get the equivalent luminance in stilb [sb].
  • Use the conversion results to interpret photometric data or update legacy measurements.

Key Features

  • Converts luminance from lambert [L] to stilb [sb]
  • Supports CGS-based photometric unit conversions
  • Ideal for optical engineering, photographic, and cinema projection contexts
  • Browser-based and easy to use with direct value input
  • Facilitates comparison of historical and modern luminance data

Examples

  • 5 Lambert [L] equals 1.591549431 Stilb [sb]
  • 0.1 Lambert [L] equals 0.03183098862 Stilb [sb]

Common Use Cases

  • Translating older CGS luminance data for optical engineering or research
  • Converting legacy photometric measurements for cinema and projection industries
  • Comparing surface brightness values in historical scientific literature
  • Calibrating and interpreting data from legacy instrumentation

Tips & Best Practices

  • Verify the measurement context to ensure applicability of CGS units
  • Use this tool to bridge older photometric data with modern formats
  • Be cautious when interchanging these units with SI units, requiring additional conversions
  • Consider measurement conditions such as reflectance and viewing angle for accurate comparisons

Limitations

  • Lambert and stilb are non-SI units and not widely used in contemporary systems
  • Precision depends on correct use within the CGS framework
  • Additional steps are needed when converting to SI units like candela per square meter
  • Measurement conditions may influence practical luminance comparison despite unit conversion

Frequently Asked Questions

What are lambert and stilb units used for?
They are CGS photometric units measuring luminance, historically used in optical engineering, photography, cinema projection, and scientific research.

Why convert from lambert to stilb?
To translate older CGS luminance data into another CGS unit, helping compare and unify legacy photometric measurements.

Are lambert and stilb units compatible with SI units?
Both are non-SI units, so converting to SI units like candela per square meter requires additional conversions and context consideration.

Key Terminology

Lambert [L]
A CGS unit of luminance for self-luminous or diffusely reflecting surfaces; equals 1/π candela per square centimetre.
Stilb [sb]
A CGS photometric unit of luminance equal to 10,000 candela per square meter, representing luminous intensity per unit area.
Luminance
A measurement of the luminous intensity emitted or reflected from a surface in a given direction per unit area.
