What Is This Tool?

This converter enables you to translate luminous intensity measurements from the German candle, an old unit used in German-speaking regions, to the pentane candle (10 candle power), a historical unit based on pentane combustion. Both units have historical significance in early lighting and photometry before the adoption of the candela.

How to Use This Tool?

  • Enter the value in candle (German) units that you wish to convert
  • Select the source unit as candle (German) [c (German)] and target unit as pentane candle (10 candle power)
  • Click the convert button to see the result expressed in pentane candle units
  • Use the provided examples to verify your conversions
  • Apply conversions to compare or interpret historical lighting data

Key Features

  • Converts between two obsolete luminous intensity units used historically in 19th and early 20th centuries
  • Supports interpretation of vintage lighting specifications and archival measurement data
  • Browser-based, user-friendly interface for quick conversion calculations
  • Provides clear examples illustrating conversion calculations
  • Assists in museum curation, restoration, and historical research contexts

Examples

  • 5 candle (German) equals approximately 0.5263 pentane candle (10 candle power)
  • 10 candle (German) equals approximately 1.0526 pentane candle (10 candle power)

Common Use Cases

  • Interpreting historic luminous intensity ratings recorded in the German candle unit
  • Comparing and translating early lighting measurements to other historical candle-based units
  • Supporting restoration of vintage lamps with original German candle specifications
  • Documenting museum lighting equipment with authentic historical photometric data
  • Conducting archival research on 19th and early 20th-century illumination technologies

Tips & Best Practices

  • Double-check historical sources for unit definitions due to possible regional or temporal variations
  • Use the conversion primarily for historical or archival interpretation rather than modern applications
  • Combine conversions with historical context to better understand obsolete lighting standards
  • Rely on examples provided to confirm calculation methods
  • Document conversions clearly when citing or comparing historical luminous intensity data

Limitations

  • Both candle (German) and pentane candle units are obsolete and replaced by SI candela
  • Conversion accuracy may be limited by historical variations in unit definitions
  • Intended for specialized or archival use, not for contemporary technical applications

Frequently Asked Questions

What is the candle (German) unit?
It is an obsolete German luminous intensity unit based on the light from a standardized flame, historically linked to lamps like the Hefner lamp and used in German-speaking countries.

What does pentane candle (10 candle power) measure?
This unit measures luminous intensity from a standardized candle burning pentane, defined as 10 times the traditional candle unit and used historically before the candela was adopted.

Why convert between these historical units?
Conversion helps interpret and compare historic lighting specifications from different regions or periods, aiding research, restoration, and museum documentation.

Is this conversion suitable for modern lighting?
No, these units are obsolete and conversions are primarily for historical or archival study rather than practical modern use.

Key Terminology
