What Is This Tool?
This unit converter enables users to transform measurements from the decimal candle to the candle (German) [c (German)], two historical units of luminous intensity. It is designed to assist with the interpretation of old lighting specifications and archival materials.
How to Use This Tool?
-
Enter the value in decimal candle you wish to convert
-
Select decimal candle as the input unit
-
Choose candle (German) [c (German)] as the output unit
-
Initiate conversion to obtain the equivalent value
Key Features
-
Converts luminous intensity from decimal candle to candle (German) [c (German)]
-
Facilitates comparison of 19th-century photometric standards
-
Supports historical research, restoration, and museum documentation
-
Easy to use and browser-based tool
Examples
-
5 Decimal candles = 5 × 0.95 = 4.75 Candle (German) [c (German)]
-
10 Decimal candles = 10 × 0.95 = 9.5 Candle (German) [c (German)]
Common Use Cases
-
Interpreting historical luminous intensity specifications in German-speaking regions
-
Comparing 19th-century photometric measurements for research or curation
-
Converting historical lamp ratings for restoration or museum records
-
Documenting older lighting standards with legacy units
Tips & Best Practices
-
Remember this conversion is mainly relevant for historical contexts
-
Use the tool to aid archival research and technical documentation
-
Consult modern units like candela for current photometric measurements
-
Understand that both units are based on varying flame standards
Limitations
-
Both units are outdated and depend on historical flame standards that varied
-
Conversion results are approximate rather than exact
-
Not suitable for modern photometric or technical applications
-
Primarily beneficial for historical and archival reference
Frequently Asked Questions
-
What is a decimal candle?
-
The decimal candle is a historical unit of luminous intensity defined by the light emitted from a standardized candle, used mainly in 19th-century photometry.
-
Why use candle (German) [c (German)]?
-
Candle (German) is an obsolete luminous intensity unit once common in German-speaking countries, useful for interpreting older German lighting standards.
-
Is this conversion exact?
-
No, the conversion is approximate since both units are based on variable flame standards and are no longer used in modern photometry.
Key Terminology
-
Decimal candle
-
A historical unit of luminous intensity defined by the standardized candle light used mainly in 19th-century photometry.
-
Candle (German) [c (German)]
-
An obsolete German unit of luminous intensity based on a standardized flame, used historically in German-speaking countries.
-
Luminous intensity
-
A measure of the wavelength-weighted power emitted by a light source in a particular direction.
