What Is This Tool?

This converter assists in changing luminous intensity values from the candle (pentane) unit, based on pentane-fueled flame light, to the German candle unit, a historical measure used in German-speaking regions. It aids in understanding and comparing old lighting data.

How to Use This Tool?

  • Enter the luminous intensity value measured in candle (pentane).
  • Select candle (pentane) as the source unit and candle (German) [c (German)] as the target unit.
  • Click the convert button to receive the equivalent value in German candles.

Key Features

  • Facilitates conversion between two obsolete luminous intensity units used historically.
  • Supports accurate interpretation of vintage photometric and lamp specifications.
  • Browser-based and straightforward interface for quick unit conversion.

Examples

  • 5 candle (pentane) equals 4.75 candle (German) [c (German)]
  • 10 candle (pentane) equals 9.5 candle (German) [c (German)]

Common Use Cases

  • Analyzing and comparing early 19th to early 20th-century photometric data recorded with different luminous intensity standards.
  • Calibrating and reproducing historic lighting conditions for museums or restoration projects.
  • Educational exploration of the history and evolution of lighting measurement units.

Tips & Best Practices

  • Always verify the historical context and original measurement standards when interpreting converted values.
  • Use this tool primarily for research, conservation, and educational purposes.
  • Cross-reference converted data with modern candela values if greater precision is required.

Limitations

  • Both units are outdated and non-SI, with definitions that depended on specific historical apparatus.
  • Conversion accuracy may be affected by inconsistencies in original measurements.
  • Not intended for modern technical applications requiring standard SI units.

Frequently Asked Questions

What is candle (pentane)?
It is a historic luminous intensity unit based on the light from a standardized pentane-fuel flame used in early photometry and lamp testing.

How does candle (German) differ from candle (pentane)?
The candle (German) is an obsolete unit used in German-speaking countries, based on a standardized flame, measuring luminous intensity in a direction, differing slightly in definition and value from candle (pentane).

Why do I need to convert between these two units?
Conversion helps interpret and compare old lighting measurements recorded with different historical standards, which is important for restoration, museum work, or historical research.

Key Terminology

Candle (pentane)
A historical luminous intensity unit based on light emitted by a standardized pentane-fueled flame, used in early photometry.
Candle (German) [c (German)]
An obsolete German luminous intensity unit based on a standardized flame, historically used before adoption of the candela.
Luminous Intensity
A measure of the wavelength-weighted power emitted by a light source in a particular direction, perceived by the human eye.
