Frequently Asked Questions

Why is the international candle unit considered obsolete?
The international candle was a historical photometric unit used before the modern SI candela was adopted, making it outdated for current scientific measurements.

In what contexts is converting between these candles useful?
Conversion is valuable when interpreting historical lighting documents, restoring period lighting, or translating archival photometric data into modern terms.

Does this tool provide conversions to modern candela units?
This tool specifically converts between candle (international) and candle (UK) units; conversions to candela require additional steps using other references.

Key Terminology

Candle (international)
An obsolete unit that historically quantified luminous intensity based on a standard lamp reference before the SI candela was standardized.
Candle (UK)
A deprecated British luminous intensity unit defined by the light from a specific candle used in UK photometry before adopting candela.
Luminous Intensity
A photometric measure of the wavelength-weighted power emitted by a light source in a particular direction.
