This converter allows you to transform luminous intensity measurements from the obsolete British unit candle (UK) to the historically used international candle. It facilitates accurate comparison and interpretation of lighting data from older British and international photometric standards.

How to Use This Tool?

  • Enter the luminous intensity value in candle (UK) units
  • Select candle (UK) as the starting unit and candle (international) as the target unit
  • Click the convert button to get the equivalent value in candle (international)
  • Use the result for historical data analysis or legacy lighting comparison

Key Features

  • Converts between candle (UK) and candle (international) luminous intensity units
  • Supports historical lighting data interpretation and restoration efforts
  • Browser-based tool accessible without installation
  • Useful for comparing legacy photometric values in older standards and literature

Examples

  • Convert 5 candle (UK) to candle (international): 5 × 1.0416666667 = 5.2083333335 candle (international)
  • Convert 10 candle (UK) to candle (international): 10 × 1.0416666667 = 10.416666667 candle (international)

Common Use Cases

  • Restoring period lighting conditions in museums and historic venues
  • Converting early photometric data to legacy international units for comparative research
  • Translating older lighting standards into modern values using intermediate conversions

Tips & Best Practices

  • Always verify the historical context when working with obsolete units
  • Use this conversion as a step before translating values to modern SI candela
  • Apply conversions carefully when restoring lighting to preserve authenticity
  • Be aware of slight historical variations in measurement standards

Limitations

  • Both candle (UK) and candle (international) are outdated and replaced by the candela
  • Historical measurement inconsistencies may cause minor variation in values
  • Not suitable for precise modern photometric calculations
  • Recommended to convert results into SI candela for contemporary applications

Frequently Asked Questions

What are candle (UK) and candle (international) units?
They are obsolete luminous intensity units historically used before the adoption of the candela. Candle (UK) was based on a standard candle in British practice, while candle (international) referred to a standard lamp used internationally.

Why convert candle (UK) to candle (international)?
Converting these units allows for accurate comparison of historical lighting specifications from British and international sources before modern SI standards.

Are these units used in modern lighting measurements?
No, both units are obsolete and modern photometric measurements use the SI unit candela instead.

Key Terminology

Candle (UK)
An obsolete British luminous intensity unit based on the light from a standardized candle used before the SI candela.
Candle (international)
A former photometric unit representing the luminous intensity of a standard lamp used internationally before the candela.
Candela
The modern SI unit of luminous intensity, replacing older units like candle (UK) and candle (international).
