A reliable Luminance converter helps bridge the gap between light measurements used by engineers, photographers, and hobbyists. Whether you need a quick Luminance converter calculator for lumens calculation or a deeper conversion between candela units like candela/square meter [cd/m²] and foot-lambert [fL], this tool makes the math fast and clear.
Try a dedicated Luminance converter app when you're in the field; many offer saved presets for candela, stilb, and lambert.
- For fast checks, a Google convert search often handles basic Luminance converter needs, but dedicated apps give more control and unit options.
Units made simple
- The unit candela/square meter [cd/m²] is common for displays.
- stilb [sb], lambert [L] are older units.
- Foot-lambert [fL] is often preferred in theater.
A complete toolbox pairs a Luminance converter with other utilities like a Charge Converter to fit into a larger workflow.
What does a luminance meter do?
It measures how much light a surface emits in candelas per square meter (cd/m²).
Is luminance the same as lumens?
No. Luminance is intensity per area (cd/m²); lumens are total light output.
Is luma the same as luminance?
Luma (video signal) approximates perceived brightness and is related to luminance but not identical.
