What Is This Tool?
This unit converter transforms luminous intensity values from the candle (UK), an outdated British measurement, to the candle (German), a former German photometric unit. It facilitates comparison and interpretation of historical lighting data.
How to Use This Tool?
-
Enter the numerical luminous intensity value in candle (UK).
-
Select candle (UK) as the source unit and candle (German) as the target unit.
-
Click convert to obtain the equivalent value in candle (German).
-
Use results to support historical lighting research or archival documentation.
Key Features
-
Converts obsolete luminous intensity units: candle (UK) to candle (German).
-
Based on historical definitions of British and German standard candles.
-
Supports analysis and restoration of vintage lighting specifications.
-
Browser-based and easy to use for quick conversions.
Examples
-
Convert 1 candle (UK) to candle (German): 1 c (UK) = 0.9896 c (German).
-
Convert 10 candle (UK) to candle (German): 10 c (UK) = 9.896 c (German).
Common Use Cases
-
Interpreting British archival luminous intensity data from historical documents.
-
Restoring illumination levels in museums and historic buildings.
-
Translating German candle data for comparative photometric studies.
-
Documenting period lighting equipment with original unit ratings.
Tips & Best Practices
-
Verify historical measurement context before converting units.
-
Use conversions for comparative and archival research purposes.
-
Cross-check results when restoring original lighting conditions.
-
Remember both units are obsolete and replaced by the candela.
Limitations
-
Both candle (UK) and candle (German) units are no longer in active use.
-
Accuracy may be affected by historical measurement differences.
-
Standardization varied between original candles and lamps.
-
Results serve mainly for historical and comparative analysis.
Frequently Asked Questions
-
What was the candle (UK) unit based on?
-
The candle (UK) was historically defined by the light from a standardized candle used in British photometric practice before adopting the candela.
-
Why convert from candle (UK) to candle (German)?
-
Conversion allows comparison of historical luminous intensity data between British and German systems for restoration and archival research.
-
Are candle (UK) and candle (German) still used today?
-
No, both units are obsolete and have been replaced by the SI unit candela.
Key Terminology
-
Candle (UK)
-
An obsolete British luminous intensity unit defined by a standardized candle used historically before the candela.
-
Candle (German)
-
An outdated German luminous intensity unit based on a standardized flame such as the Hefner lamp, replaced by the candela.
-
Luminous Intensity
-
A photometric measure of the wavelength-weighted power emitted by a light source in a particular direction.
