How to Convert Mean Spherical Candlepower to Lumens
The candlepower (mean spherical) and lumen are both units of luminous flux. 1 candlepower (mean spherical) equals 12.566 lumens. This means to convert mean spherical candlepower to lumens, you multiply by 12.566.
Formula
Step-by-Step Example
Convert 5 MSCP to lumens:
We need to convert mean spherical candlepower to lumens
Since 1 MSCP = 12.566 lm, multiply by 12.566
5 × 12.566 = 62.83
5 MSCP = 62.83 lm

About These Units
Candlepower (Mean Spherical) (MSCP)
Mean Spherical Candlepower (MSCP) is an obsolete unit for total light output. One MSCP equals 4π (≈12.57) lumens—the light from a 1-candela source radiating uniformly in all directions. Found on vintage bulb packaging. Replaced by lumens in modern specifications.
Lumen (lm)
The lumen (lm) is the SI unit of luminous flux, measuring total visible light output from a source. Common bulb outputs: 40W incandescent ≈ 450 lm, 60W equivalent LED ≈ 800 lm, 100W equivalent ≈ 1,600 lm. Projector: 3,000-10,000 lm. One lumen = one candela × one steradian.
