lumen (Library of Units and Constants

Name:
lumen
(convert lumen to new units)

Abbreviation:
lm

Quantity:
luminous_flux

Metric (SI) Equivalent:
lumen is a metric unit (in fact, it is a derived SI unit)
1 candela steradian

Metric (SI) Dimensions:
luminous-intensity × solid-angle

Notes:
(1) Even though the steradian is a dimensionless derived unit and could be dropped, it is shown in the metric (SI) equivalent for clarity.
(2) Even though solid-angle is not an official metric (SI) dimension and could be dropped, it is shown in the dimensions for clarity.
