nttosb
Convert nits (nt) to stilbs (sb).
Factor1 nt = 0.0001 sb
Converter
nt
Accepts numbers or expressions, e.g. 150 + 14.7
Result
sb
Rendered to 6 significant figures.
Formula
Formula
sb = nt × 0.0001
Multiply any value in nits by 0.0001 to obtain the value in stilbs.
Worked example
Convert 10000 nt to sb.
- 01Start with 10000 nt.
- 02Multiply by the conversion factor: 10000 × 0.0001 = 1 sb.
Result10000 nt = 1 sb

FAQ
What is the conversion factor from nt to sb?
1 nt equals 0.0001 sb. To convert, multiply the value in nits by 0.0001.
How do I convert 1 nt to sb?
1 nt = 0.0001 sb. For any value, multiply by 0.0001.
How do I convert sb back to nt?
Divide by the same factor — or equivalently, multiply by 10000. So 1 sb = 10000 nt.
When would I need to convert nit to stilb?
Luminance conversions between nt and sb are used in display engineering, road and traffic-signal design, and photometric measurement of luminous surfaces. cd/m² (nit) is the SI standard; foot-lambert and stilb appear in legacy datasheets and specialist optics work.
Is the conversion exact?
The factor shown is precise to at least 7 significant figures. For most process-engineering work this is far better than instrument accuracy. For metrology or trade applications, refer to the relevant national standard (NIST, BIPM, ISO 80000).
