Convert Stilbs to Nits (sb to cd/m2)
1 stilb (sb) = 10000 nits (cd/m²). 1 cd/m² = 0.0001 sb. Example: 15 sb = 15 × 10000 = 150000 cd/m².

How to Convert Stilb to Nit
- 1 sb = 10000 cd/m²
- 1 cd/m² = 0.0001 sb
- Example: convert 15 sb to cd/m²: 15 sb = 15 × 10000 cd/m² = 150000 cd/m²
Formula
cd/m² = sb × 10000
Derivation from SI units:
- 1 sb = 1 cd/cm² = 10⁴ cd/m².
- 1 nit = 1 cd/m².
Both units are defined exactly, so the factor is exact. Stilb definition: stilb; Nit definition: nit.
Worked examples
- A reading of 2 sb converts to 20000 cd/m².
2 sb × 10000 = 20000 cd/m² - A value of 20 sb is 200000 cd/m².
20 sb × 10000 = 200000 cd/m²

Where it's used
Stilbs are used for older optics and lamp data, while nits appear in display brightness (phones, monitors, TVs). Both measure luminance (brightness of a surface or screen), so the conversion is a fixed factor.
