Convert Gigalumen to Candela Steradian
Enter the number of gigalumens that you want to convert to candela steradians.
How to Convert Gigalumens to Candela Steradians
The gigalumen and candela steradian are both units of luminous flux. By definition, 1 gigalumen equals exactly 1000000000 candela steradians. This means to convert gigalumens to candela steradians, you multiply by 1000000000.
Formula
Step-by-Step Example
Convert 5 Glm to candela steradians:
We need to convert gigalumens to candela steradians
Since 1 Glm = 1000000000 cd·sr, multiply by 1000000000
5 × 1000000000 = 5000000000
5 Glm = 5000000000 cd·sr

About These Units
Gigalumen (Glm)
A gigalumen (Glm) equals 10⁹ lumens. Theoretical scale for astronomical measurements. The Sun outputs approximately 3.8×10²⁸ lumens (38 quadrillion gigalumens). Used only in astrophysical contexts comparing stellar luminosity.
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.
