What Is This Tool?

This converter helps transform luminous intensity measurements from the obsolete British unit candle (UK) [c (UK)] into the historical candle (pentane) unit. Both units were used historically as practical standards based on standardized flame sources before the adoption of the candela as the SI unit.

How to Use This Tool?

  • Enter the luminous intensity value in candle (UK) [c (UK)].
  • Select candle (UK) [c (UK)] as the source unit.
  • Choose candle (pentane) as the target unit.
  • Click the convert button to get the equivalent value in candle (pentane).
  • Use the result to interpret or reproduce historical lighting data accurately.

Key Features

  • Convert between two obsolete luminous intensity units based on standardized candle flames.
  • Provides accurate conversion using a specific conversion rate.
  • Supports translation of historical photometric data for museums, restoration, and research.
  • Browser-based and easy to use without installation.
  • Facilitates comparison of 19th and early 20th century lighting measurements.

Examples

  • 1 candle (UK) [c (UK)] equals 1.0416666667 candle (pentane).
  • 10 candles (UK) [c (UK)] converts to 10.416666667 candle (pentane).

Common Use Cases

  • Interpreting historical lighting specifications from British archives.
  • Restoring period-accurate lighting in museums and historic sites.
  • Converting early photometric data to compare with pentane-based measurements.
  • Recreating original illumination levels for theatrical lighting reconstructions.
  • Educational demonstrations on the history of light measurement standards.

Tips & Best Practices

  • Always verify the context and source of historical measurements before conversion.
  • Use the tool for interpretation and comparison rather than precise modern measurements.
  • Combine the converter results with historical documentation to ensure accuracy.
  • Prefer SI units like the candela for modern scientific and engineering work.
  • Consult experts when reproducing lighting for museums or historical reconstructions.

Limitations

  • Both candle (UK) and candle (pentane) are obsolete and non-SI units.
  • The exact equivalence of candle (pentane) can vary with original apparatus and definition.
  • This converter is not intended for precise modern photometric calculations.
  • Modern lighting measurements should rely on the candela for accuracy.

Frequently Asked Questions

What is the candle (UK) unit?
The candle (UK) [c (UK)] is an obsolete British luminous intensity unit based on a standardized candle flame used in UK photometry before the candela standard.

Why convert to candle (pentane)?
Converting to candle (pentane) helps compare or interpret historical photometric measurements where the pentane candle standard was used, supporting accurate restoration and research.

Can this tool be used for modern light measurements?
No, both units are obsolete; for modern accuracy, the candela, the SI unit of luminous intensity, should be used instead.

Key Terminology

Candle (UK) [c (UK)]
An obsolete British luminous intensity unit defined by the light of a standardized candle used before the SI candela.
Candle (pentane)
A historical luminous intensity unit based on a standardized pentane-fuel flame, used in early photometry and replaced by the candela.
Luminous Intensity
A measure of the wavelength-weighted power emitted by a light source in a particular direction, historically expressed in candle-based units.
Candela
The modern SI unit of luminous intensity that has superseded candle-based units.
