Convert Candela Steradian to Kilolumen
Type the number of candela steradians that you wish to convert to kilolumens.
How to Convert Candela Steradians to Kilolumens
The candela steradian and kilolumen are both units of luminous flux. By definition, 1 kilolumen equals exactly 1000 candela steradians. This means to convert candela steradians to kilolumens, you divide by 1000.
Formula
Step-by-Step Example
Convert 5 cd·sr to kilolumens:
We need to convert candela steradians to kilolumens
Since 1 klm = 1000 cd·sr, divide by 1000
5 ÷ 1000 = 0.005
5 cd·sr = 0.005 klm

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.
Kilolumen (klm)
A kilolumen (klm) equals 1,000 lumens. Used for powerful light sources: high-end projector 3-10 klm, car headlight 1-3 klm, stadium floodlight 20-100 klm, IMAX projector 30+ klm. Convenient for specifying commercial lighting installations.
