= 618.65877751 (cd) This calculator uses a particular formula in performing the calculations. Formula of calculating lumens to candela Iv (cd) = фv (lm) / Ω (sr), which means that for a uniform isotropic light source, the luminous intensity in candela is calculated by dividing the luminous flux in lumens by the solid angle in steradians.
Convert candela to lumens using this calculator I (cd) to ϕ (lm) 💡
Do a quick conversion: 1 lumen = 1 candela using the online calculator for metric conversions. Check the chart for more details.

How to calculate lumens from candela. Both candela and lumen are units of emitted light. If you know one of these two values (either luminous intensity or luminous flux), you can easily convert to the other. As mentioned earlier, candelas are a measure of light output per steradian (solid angle unit). This means that this value is independent.
Candela to Lumen Conversion Calculation Angle Light
To convert from candela to lumen, multiply the value in candela by the angular span of the light source in steradia: Lumen = Candelas * Ω. For a light source that emits light uniformly in all directions, Ω = 4π. Steradians are a unit for measuring angles in a 3D space (just like radians for a 2D space). A steradian on a sphere with a radius.
