Frequently Asked Questions

What is the candle (German) unit?
It is an obsolete German unit of luminous intensity historically used in German-speaking regions, based on a standardized flame and replaced by the candela.

How is lumen per steradian related to candle (German)?
Lumen per steradian measures luminous intensity and is numerically equivalent to the candela. One candle (German) equals approximately 1.0526 lumen per steradian.

Why convert candle (German) to lumen per steradian?
Converting helps interpret historical luminous intensity data in modern terms, supporting research, restoration, and technical analysis involving lighting equipment.

Key Terminology

Candle (German) [c (German)]
An obsolete German luminous intensity unit based on light from a standardized flame, historically used before the SI candela.
Lumen/steradian [lm/sr]
A unit of luminous intensity quantifying luminous flux emitted per unit solid angle, equivalent to the SI candela.
