Convert Nits to Stilbs (cd/m2 to sb)
1 nit (cd/m²) = 0.0001 stilbs (sb). 1 sb = 10000 cd/m². Example: 15 cd/m² = 15 × 0.0001 = 0.0015 sb.

How to Convert Nit to Stilb
- 1 cd/m² = 0.0001 sb
- 1 sb = 10000 cd/m²
- Example: convert 15 cd/m² to sb: 15 cd/m² = 15 × 0.0001 sb = 0.0015 sb
Formula
sb = cd/m² ÷ 10000
Derivation from SI units:
- 1 nit = 1 cd/m².
- 1 sb = 1 cd/cm² = 10⁴ cd/m².
Both units are defined exactly, so the factor is exact. Nit definition: nit; Stilb definition: stilb.
Worked examples
- A reading of 500 cd/m² converts to 0.05 sb.
500 cd/m² × 0.0001 = 0.05 sb - A value of 1600 cd/m² is 0.16 sb.
1600 cd/m² × 0.0001 = 0.16 sb

| 10000 cd/m² | 1 sb |
Where it's used
Nits are used for display brightness (phones, monitors, TVs), while stilbs appear in older optics and lamp data. Both measure luminance (brightness of a surface or screen), so the conversion is a fixed factor.

Frequently asked questions
How many stilbs are in 1 nit?
1 cd/m² = 0.0001 sb.
How do I convert nits to stilbs?
Multiply the value in cd/m² by 0.0001, or divide it by 10000. For example, 15 cd/m² × 0.0001 = 0.0015 sb.
Is the cd/m² to sb conversion exact?
Yes. Both units are defined exactly, and 1 cd/m² is exactly 0.0001 sb.
