Convert Nits to Lamberts (cd/m2 to L)
1 nit (cd/m²) = 0.0003141592654 lamberts (L). 1 L = 3183.098862 cd/m². Example: 15 cd/m² = 15 × 0.0003141592654 = 0.00471238898 L.

How to Convert Nit to Lambert
- 1 cd/m² = 0.0003141592654 L
- 1 L = 3183.098862 cd/m²
- Example: convert 15 cd/m² to L: 15 cd/m² = 15 × 0.0003141592654 L = 0.00471238898 L
Formula
L = cd/m² × 0.000314159265359
or L = cd/m² ÷ 3183.098861838
Derivation from SI units:
- 1 nit = 1 cd/m².
- 1 L = (1/π) cd/cm² ≈ 3183 cd/m².
Both units are defined exactly, so the factor is exact. Nit definition: nit; Lambert definition: lambert.
Worked examples
- A reading of 500 cd/m² converts to 0.1570796327 L.
500 cd/m² × 0.0003141592654 = 0.1570796327 L - A value of 1600 cd/m² is 0.5026548246 L.
1600 cd/m² × 0.0003141592654 = 0.5026548246 L

Where it's used
Nits are used for display brightness (phones, monitors, TVs), while lamberts appear in older vision-science literature. Both measure luminance (brightness of a surface or screen), so the conversion is a fixed factor.

Frequently asked questions
How many lamberts are in 1 nit?
1 cd/m² = 0.0003141592654 L.
How do I convert nits to lamberts?
Multiply the value in cd/m² by 0.0003141592654, or divide it by 3183.098862. For example, 15 cd/m² × 0.0003141592654 = 0.00471238898 L.
Is the cd/m² to L conversion exact?
Yes. Both units are defined exactly, so the ratio is exact; its decimal form does not terminate and is shown here to 10 significant figures (more with the precision selector).
