Limitations
- Both candle (international) [c] and carcel units are obsolete and not applicable in modern photometry.
- Conversion results serve historical reference purposes and may lack strict accuracy.
- Original measurement methods and lamp specifications were inconsistent, affecting reliability.
- Units do not directly equate to modern SI candela without further conversion procedures.
Frequently Asked Questions
- What is the candle (international) unit?
- The candle (international) is an outdated photometric unit once used to specify luminous intensity based on a standard lamp prior to adopting the modern candela.
- What does the carcel unit measure?
- The carcel unit is a historical measure of luminous intensity defined by the light emitted from a standardized oil lamp used in the 19th century.
- Why convert between candle (international) and carcel units?
- Conversions help bridge historical lighting data and facilitate understanding of old photometric measurements in research or restoration contexts.
Key Terminology
- Candle (international) [c]
- An obsolete photometric unit historically used to define luminous intensity based on a standard lamp prior to the candela.
- Carcel unit
- A historical luminous intensity unit defined by the brightness of a standardized Carcel oil lamp from the 19th century.
- Luminous intensity
- A photometric measurement of the amount of light emitted in a particular direction, historically measured by units like candle (international) and carcel.
