Convert Millilumen to Candela Steradian
Input the number of millilumens you want to convert to candela steradians.
How to Convert Millilumens to Candela Steradians
The millilumen and candela steradian are both units of luminous flux. By definition, 1 millilumen equals exactly 1000000 candela steradians. This means to convert millilumens to candela steradians, you multiply by 1000000.
Formula
Step-by-Step Example
Convert 5 mlm to candela steradians:
We need to convert millilumens to candela steradians
Since 1 mlm = 1000000 cd·sr, multiply by 1000000
5 × 1000000 = 5000000
5 mlm = 5000000 cd·sr

About These Units
Millilumen (mlm)
A millilumen (mlm) equals 0.001 lumens. Used for very dim sources: indicator LEDs (1-20 mlm), phosphorescent materials, watch dial luminescence, and fiber optic output measurements. Useful for specifying minimum detectable light levels in optical sensors.
Candela Steradian (cd·sr)
A candela steradian (cd·sr) is the defining relationship for lumens: 1 lumen = 1 candela × 1 steradian. Shows how luminous flux relates to luminous intensity (candelas) and solid angle (steradians). A sphere has 4π ≈ 12.57 steradians total solid angle.
