What Is This Tool?

This converter transforms luminous intensity measurements from the bougie decimal, an obsolete French unit, into pentane candle (10 candle power), a non-SI unit based on pentane-burning candles historically used before the candela was established.

How to Use This Tool?

  • Enter the value in bougie decimal that you wish to convert.
  • Select bougie decimal as the source unit and pentane candle (10 candle power) as the target unit.
  • Click the convert button to get the equivalent luminous intensity in pentane candle (10 candle power).
  • Use the results to compare or analyze historical luminous intensity data effectively.

Key Features

  • Converts obsolete luminous intensity units from bougie decimal to pentane candle (10 candle power).
  • Supports historical and archival research involving 19th and early 20th-century lighting measurements.
  • Browser-based, easy-to-use interface for quick unit transformation.
  • Assists in interpreting vintage photometric data and technical documents.

Examples

  • 5 bougie decimal equals 0.5 pentane candle (10 candle power).
  • 10 bougie decimal equals 1 pentane candle (10 candle power).

Common Use Cases

  • Translating 19th and early 20th century French luminous intensity values for research.
  • Restoring and documenting antique lighting fixtures with historical measurement units.
  • Studying the development of photometry and international unit standardization.
  • Interpreting old lighting specifications and museum catalog entries.

Tips & Best Practices

  • Always verify historical context when converting to ensure correct interpretation of values.
  • Use this converter primarily for archival or educational purposes rather than precise scientific calculations.
  • Be aware of the approximate nature of conversions due to historical variations in candle properties.
  • Cross-check converted results with reference materials on historical photometric units.

Limitations

  • Both bougie decimal and pentane candle are obsolete and non-SI units primarily for historical reference.
  • Conversion values are approximate due to inconsistencies in historical candle manufacturing and combustion.
  • Not suitable for modern scientific or engineering applications requiring precise luminous intensity measures.

Frequently Asked Questions

What is the bougie decimal unit?
The bougie decimal is a historic French luminous intensity unit used during 19th and early 20th century metrication, now replaced by the SI candela.

How does the pentane candle (10 candle power) relate to traditional candle units?
The pentane candle (10 candle power) is a historical unit equal to ten times the traditional candle, based on a standard candle burning pentane.

Can I use this converter for precise scientific measurements?
No, this converter is intended for historical and archival use, as the units involved are obsolete and the exact equivalence is approximate.

Key Terminology

Bougie Decimal
An obsolete French unit of luminous intensity historically used as a decimal-based candle measure before the candela was adopted.
Pentane Candle (10 Candle Power)
A historical luminous intensity unit defined by a standard candle burning pentane, equivalent to ten traditional candle power.
Luminous Intensity
A photometric measure of the wavelength-weighted power emitted by a light source in a particular direction.
