What Is This Tool?

This converter allows you to switch luminous intensity measurements from the candle (pentane), a 19th-century non-SI unit based on pentane-fuel flame light, into candle (UK) [c (UK)], an old British luminous intensity unit defined by a standardized candle. It helps interpret historical photometric data and restore period lighting accurately.

How to Use This Tool?

  • Enter the luminous intensity value in candle (pentane).
  • Select the target unit as candle (UK) [c (UK)].
  • Click the convert button to calculate the equivalent luminous intensity.
  • Review the converted value based on the historical unit conversion factor.
  • Use the result for analysis, comparison, or restoration projects.

Key Features

  • Converts between two historical luminous intensity units: candle (pentane) and candle (UK) [c (UK)].
  • Based on established conversion formula derived from these obsolete standards.
  • Supports accurate interpretation of 19th and early 20th-century lighting measurements.
  • Ideal for museum conservation, historical research, and educational purposes.
  • Easy-to-use online interface for straightforward unit conversion.

Examples

  • Convert 5 candle (pentane) to candle (UK): 5 × 0.96 = 4.8 candle (UK) [c (UK)].
  • Convert 10 candle (pentane) to candle (UK): 10 × 0.96 = 9.6 candle (UK) [c (UK)].

Common Use Cases

  • Interpreting early photometric measurements and lighting specs that use pentane candle standards.
  • Calibrating or reproducing lighting for museums and conservation requiring period-accurate illumination.
  • Studying historical photometry and the evolution of light measurement units.
  • Restoring historical lighting in theatres and heritage buildings to original standards.
  • Converting British archival lighting data for comparison or analysis.

Tips & Best Practices

  • Verify the historical context of your photometric data before conversion.
  • Use conversions primarily for educational, historical research, or conservation work.
  • Be aware the units are obsolete and may have varied historically based on apparatus.
  • Compare converted values cautiously due to approximate definitions and conditions.
  • Document the source and conversion method when applying this data.

Limitations

  • Both candle (pentane) and candle (UK) are outdated and non-SI units.
  • Their definitions varied historically and depend on specific measurement equipment.
  • Conversion represents an approximation rather than precise equivalence.
  • Not suitable for modern photometric precision or scientific purposes.
  • Primarily intended for historical interpretation, educational use, and conservation.

Frequently Asked Questions

What is candle (pentane)?
Candle (pentane) is a historical luminous intensity unit based on a standard pentane-fuel flame, used as a reference in early photometry before modern SI units.

Why convert candle (pentane) to candle (UK)?
Converting between these units helps interpret and compare historical lighting data from different 19th and early 20th century standards, useful in research and restoration.

Is this conversion precise for modern applications?
No, both units are obsolete and approximate; this conversion is intended for historical and educational purposes rather than modern photometric accuracy.

Key Terminology

Candle (pentane)
A non-SI luminous intensity unit based on the light from a standardized pentane flame, used historically for photometric reference.
Candle (UK) [c (UK)]
An obsolete British luminous intensity unit defined by a standardized candle, used for photometric standards before the candela.
Luminous Intensity
The measure of the wavelength-weighted power emitted by a light source in a particular direction, perceived by the human eye.
