What Is This Tool?

This converter transforms luminous intensity measurements from lumen per steradian [lm/sr] to the bougie decimal, a historical French unit of luminous intensity that is numerically equal to lumen per steradian. It facilitates interpreting older lighting standards and photometric data.

How to Use This Tool?

  • Input the luminous intensity value in lumen per steradian [lm/sr]
  • Select the source unit as lumen/steradian [lm/sr]
  • Choose the target unit as bougie decimal
  • Click the convert button to see the equivalent value
  • Use the result for research, restoration, or educational purposes

Key Features

  • Converts luminous intensity values between lm/sr and bougie decimal seamlessly
  • Equivalence-based conversion maintaining unit value accuracy
  • Browser-based tool requiring no installation or configuration
  • Supports users working with 19th and early 20th-century photometric data
  • Helps bridge modern and historical lighting measurement systems

Examples

  • 5 lumen/steradian [lm/sr] converts to 5 bougie decimal
  • 0.75 lumen/steradian [lm/sr] converts to 0.75 bougie decimal

Common Use Cases

  • Decoding luminous intensity values in historical French lighting specifications
  • Converting old photometric measurements to modern standards for archival work
  • Supporting restoration projects involving period lighting equipment
  • Teaching photometry history and unit evolution in academic settings

Tips & Best Practices

  • Confirm the historical context before converting luminous intensity data
  • Use this tool primarily for educational and archival research purposes
  • Avoid applying the bougie decimal unit in modern photometric measurements
  • Cross-reference conversions with original documentation when possible

Limitations

  • Bougie decimal is obsolete and not used in contemporary photometry
  • Conversion assumes numerical equivalence but reflects no modern industry standards
  • Tool is designed for historical and archival applications only

Frequently Asked Questions

What is lumen per steradian [lm/sr]?
Lumen per steradian measures luminous intensity as the visible light power emitted per unit solid angle, equal to the SI candela.

What does bougie decimal mean?
The bougie decimal is an obsolete French luminous intensity unit historically used as a decimal-based candle measure.

Can this converter be used for modern lighting design?
No, the bougie decimal is obsolete and relevant only for historical, archival, or educational research.

Key Terminology

Lumen per steradian [lm/sr]
A unit of luminous intensity measuring visible light power per unit solid angle; equivalent to candela.
Bougie decimal
An outdated French unit of luminous intensity used historically as a decimal-based candle measure.
Luminous intensity
