How many nits is 1 cd/m²?

Exactly 1 nit. The nit is defined as 1 candela per square meter, so the two units are identical. No conversion factor is needed — the values are always equal.

What is a nit used for?

Nit is the informal name for cd/m² used almost exclusively in the display and lighting industries. TV, monitor, and projector brightness are routinely quoted in nits rather than the formal SI symbol cd/m².

How do I convert cd/m² to foot-lambert?

Multiply by 0.29186. For example, 500 cd/m² × 0.29186 ≈ 145.93 fL. The exact factor is 1 cd/m² = 1/π ft·L ≈ 0.31831 fL using an older definition, but the standard photometric value widely used in cinema is 0.29186 fL per cd/m².

How do I convert cd/m² to lambert?

Multiply by π/10000. Since 1 lambert = 10000/π cd/m², we get 1 cd/m² = π/10000 L ≈ 3.14159×10⁻⁴ L. For example, 500 cd/m² ≈ 0.15708 L.

What is a typical screen brightness in nits?

Typical laptop screens fall between 250–400 nits. Smartphone displays range from 400–1000 nits. HDR televisions target 1000–4000 nits for peak highlights, and professional cinema projectors often aim for about 14 fL (roughly 48 cd/m²) on the screen surface.

Summary

Enter a cd/m² value and get the equivalent in nit, foot-lambert, and lambert instantly. 1 cd/m² = 1 nit exactly.

How it works

Enter any luminance value in candela per square meter (cd/m²) in the input field.
The converter applies the 1:1 identity — nit equals cd/m² exactly.
Foot-lambert is calculated by multiplying by 0.29186 (1 cd/m² ≈ 0.29186 fL).
Lambert is calculated by multiplying by π/10000 ≈ 3.14159×10⁻⁴ L.
All results update in real time as you type; copy any value with one click.

Use cases

Confirm that a display panel spec listed in cd/m² matches its nit rating.
Convert screen brightness specs between nits and foot-lamberts for cinema projector work.
Cross-check luminance readings from a photometer against display manufacturer specs.
Translate lambert-based legacy photometric data into the modern SI unit cd/m².
Verify HDR peak-brightness claims (e.g. 1000 nit = 1000 cd/m²) for consumer displays.
