What Is This Tool?

This tool enables users to convert luminous intensity measurements from the obsolete French unit bougie decimal to the German candle (c (German)), two historical units replaced by the modern SI unit candela. It supports research, restoration, and study of early photometry standards.

How to Use This Tool?

  • Enter the luminous intensity value in bougie decimal units
  • Select bougie decimal as the original unit and candle (German) [c (German)] as the target unit
  • Click the convert button to get the equivalent value in candle (German)
  • Review the result and use it for historical data comparison or documentation

Key Features

  • Converts bougie decimal units to candle (German) [c (German)] accurately
  • Supports historical luminous intensity unit conversions
  • Browser-based and easy to use with simple input fields
  • Provides relevant context for archival and academic research
  • Displays sample calculations for quick understanding

Examples

  • 5 Bougie decimal converts to 4.75 Candle (German) [c (German)]
  • 10 Bougie decimal converts to 9.5 Candle (German) [c (German)]

Common Use Cases

  • Interpreting and converting 19th–early 20th century French lighting standards
  • Translating German historical luminous intensity specifications
  • Supporting restoration or museum documentation of antique lighting
  • Academic study of photometric history and unit development
  • Comparing historical photometric measurements between French and German units

Tips & Best Practices

  • Confirm the context is historical as these units are no longer in scientific use
  • Use the tool primarily for archival or educational purposes
  • Cross-check results where original measurement conditions might vary
  • Always consider modern SI units for current applications

Limitations

  • Both bougie decimal and candle (German) are obsolete and replaced by candela
  • Variations in historical measurement conditions may impact accuracy
  • Not suitable for modern scientific or engineering use
  • Conversion only provides approximate equivalence for historical research

Frequently Asked Questions

What is a bougie decimal?
The bougie decimal is a historic French luminous intensity unit formerly used in the 19th and early 20th centuries, now superseded by the candela.

What does the German candle measure?
The German candle was an obsolete unit of luminous intensity based on a standardized flame, historically used in German-speaking countries.

Why convert between these units?
Converting helps interpret historical lighting data, supports restoration efforts, and aids research on early photometric standards from French and German contexts.

Is this conversion used in modern science?
No, these units are obsolete; modern luminous intensity uses the SI candela unit for scientific and engineering purposes.

Key Terminology

Bougie decimal
An obsolete French unit of luminous intensity used historically before being replaced by the candela.
Candle (German) [c (German)]
An obsolete German unit of luminous intensity based on a standardized flame, now replaced by the candela.
Candela
The SI unit for luminous intensity which replaced older units like bougie decimal and German candle.
