Convert candela steradians to millilumens by entering a value below.
How to Convert Candela Steradians to Millilumens
The candela steradian and millilumen are both units of luminous flux. By definition, 1 millilumen equals exactly 1000000 candela steradians. This means to convert candela steradians to millilumens, you divide by 1000000.
Formula
Step-by-Step Example
Convert 5 cd·sr to millilumens:
We need to convert candela steradians to millilumens
Since 1 mlm = 1000000 cd·sr, divide by 1000000
5 ÷ 1000000 = 5e-6
5 cd·sr = 5e-6 mlm

About These Units
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.
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.
