All 19 luminance units are converted through a single base unit, so any unit can be converted to any other. Enter a value, choose the units and press Convert, or open a conversion page for the exact factor and a reference table.

For example, 1 candela per square meter (cd/m²) = 0.0001 candela per square centimeter (cd/cm²).

Candela per Square Meter (cd/m²)

Candela per square meter is the SI unit of luminance, the brightness of a surface. Phone and monitor brightness is specified in cd/m², also called nits.

Stilb (sb)

A stilb is one candela per square centimeter, 10,000 cd/m², an older CGS unit for very bright sources.

Nit (nt)

A nit is simply another name for one candela per square meter. Displays range from about 300 nits for laptops to over 1,000 nits for HDR televisions.

Lambert (L)

A lambert is 10,000/π cd/m² (about 3,183 cd/m²), a CGS unit defined for a perfectly diffusing surface.

Foot Lambert (fL)

A foot-lambert is about 3.426 cd/m². Cinema screens and projectors are often specified in foot-lamberts.
