How to Convert Hefnerkerzen to Microlumens
The hefnerkerze and microlumen are both units of luminous flux. By definition, 1 hefnerkerze equals exactly 10770000 microlumens. This means to convert hefnerkerzen to microlumens, you multiply by 10770000.
Formula
Step-by-Step Example
Convert 5 HK to microlumens:
We need to convert hefnerkerzen to microlumens
Since 1 HK = 10770000 μlm, multiply by 10770000
5 × 10770000 = 53850000
5 HK = 53850000 μlm

About These Units
Hefnerkerze (HK)
The Hefnerkerze (HK) is a historical German unit based on the Hefner lamp flame (amyl acetate). One Hefnerkerze ≈ 0.903 international candelas. Mean Spherical HK × 4π ≈ lumens. Used in Germany until mid-20th century; now obsolete.
Microlumen (μlm)
A microlumen (μlm) equals 10⁻⁶ lumens. Used in laboratory photometry, bioluminescence measurements (firefly: ~0.5 μlm/flash), and extremely dim light source characterization. Required precision instrumentation for measurement.
