FAQ
What is the conversion factor from nmi to ch?
1 nmi equals 92.06236 ch. To convert, multiply the value in nautical miles by 92.06236.
How do I convert 1 nmi to ch?
1 nmi = 92.0624 ch. For any value, multiply by 92.06236.
How do I convert ch back to nmi?
Divide by the same factor — or equivalently, multiply by 0.0108622. So 1 ch = 0.0108622 nmi.
When would I need to convert nautical mile to chain (Gunter's chain)?
Length conversions appear in piping, layout, and mechanical drawings — particularly when reconciling imperial fittings or instrument lengths with metric plant drawings.
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).
