Why would I need to convert between these units?

Conversion allows expression of luminance in different but equivalent units used in various industries such as display technology and lighting.

Does the conversion affect measurement accuracy?

The units being equivalent means the conversion does not change accuracy, but geometry and calibration factors do.

Key Terminology

Candela per square meter (cd/m²): The SI unit of luminance representing luminous intensity per unit projected surface area in a given direction.
Lumen per square meter per steradian (lm·m⁻²·sr⁻¹): A unit of luminance describing luminous intensity emitted or reflected per unit area per unit solid angle, equivalent to candela per square meter.
Luminance: A photometric measure of brightness quantifying how bright a surface appears to an observer from a specified direction.
Steradian: A unit of solid angle used in three-dimensional space to describe the extent of an object's projection.
