FAQ
What is the conversion factor from ftm to mil?
1 ftm equals 72000 mil. To convert, multiply the value in fathoms by 72000.
How do I convert 1 ftm to mil?
1 ftm = 72000 mil. For any value, multiply by 72000.
How do I convert mil back to ftm?
Divide by the same factor — or equivalently, multiply by 1.388889e-5. So 1 mil = 1.38889e-5 ftm.
When would I need to convert fathom to mil (thousandth of an 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).
