FAQ
What is the conversion factor from ch to in?
1 ch equals 792 in. To convert, multiply the value in chains by 792.
How do I convert 1 ch to in?
1 ch = 792 in. For any value, multiply by 792.
How do I convert in back to ch?
Divide by the same factor — or equivalently, multiply by 0.001262626. So 1 in = 0.00126263 ch.
When would I need to convert chain (Gunter's chain) to inch?
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).
