Conversion Formula

Glm = mlm × 1.000000000e-12

About Millilumens

The millilumen (mlm) equals 10⁻³ lm. The output range for typical LED indicator packages: a standard 5 mm through-hole LED at 20 mA produces 10-200 mlm depending on color and efficiency. Small wearable health-monitor LEDs and remote-control emitter LEDs operate in this range. 1 mlm = 10⁻³ lm.

About Gigalumens

The gigalumen (Glm) equals 10⁹ lm. The scale for very large lighting installations and for theoretical comparisons: a large airport apron illuminated to 30 lx over 1 km² would require approximately 30 Glm of total installed luminous flux. The full-disk luminous flux of the Sun is approximately 3.6 × 10²⁸ lm. 1 Glm = 10⁹ lm.
