Formula
Formula
nt = cd/m² × 1
Multiply any value in candelas per square metre by 1 to obtain the value in nits.
Worked example
Convert 100 cd/m² to nt.
- 01Start with 100 cd/m².
- 02Multiply by the conversion factor: 100 × 1 = 100 nt.
Result100 cd/m² = 100 nt

FAQ
What is the conversion factor from cd/m² to nt?
1 cd/m² equals 1 nt. To convert, multiply the value in candelas per square metre by 1.
How do I convert 1 cd/m² to nt?
1 cd/m² = 1 nt. For any value, multiply by 1.
How do I convert nt back to cd/m²?
Divide by the same factor — or equivalently, multiply by 1. So 1 nt = 1 cd/m².
When would I need to convert candela per square metre to nit?
Luminance conversions between cd/m² 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).
