Formula
Formula
nt = sb × 10000
Multiply any value in stilbs by 10000 to obtain the value in nits.
Worked example
Convert 1 sb to nt.
- 01Start with 1 sb.
- 02Multiply by the conversion factor: 1 × 10000 = 10000 nt.
Result1 sb = 10000 nt

FAQ
What is the conversion factor from sb to nt?
1 sb equals 10000 nt. To convert, multiply the value in stilbs by 10000.
How do I convert 1 sb to nt?
1 sb = 10000 nt. For any value, multiply by 10000.
How do I convert nt back to sb?
Divide by the same factor — or equivalently, multiply by 0.0001. So 1 nt = 0.0001 sb.
When would I need to convert stilb to nit?
Luminance conversions between sb and nt 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).
