Convert Lumens to Megalumens
Input the number of lumens you want to convert to megalumens.
How to Convert Lumens to Megalumens
The lumen and megalumen are both units of luminous flux. By definition, 1 megalumen equals exactly 1000000 lumens. This means to convert lumens to megalumens, you divide by 1000000.
Formula
Step-by-Step Example
Convert 5 lm to megalumens:
We need to convert lumens to megalumens
Since 1 Mlm = 1000000 lm, divide by 1000000
5 ÷ 1000000 = 5e-6
5 lm = 5e-6 Mlm

About These Units
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.
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.
