Convert Candela Steradian to Megalumen
Input the number of candela steradians you want to convert to megalumens.
How to Convert Candela Steradians to Megalumens
The candela steradian and megalumen are both units of luminous flux. By definition, 1 megalumen equals exactly 1000000 candela steradians. This means to convert candela steradians to megalumens, you divide by 1000000.
Formula
Step-by-Step Example
Convert 5 cd·sr to megalumens:
We need to convert candela steradians to megalumens
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.
Megalumen (Mlm)
A megalumen (Mlm) equals 1,000,000 lumens. Measures large-scale lighting: stadium lighting system 1-5 Mlm total, lighthouse beacon, and large searchlights. An average sports stadium uses 2-5 megalumens for night games.
