ydtoftm
Convert yards (yd) to fathoms (ftm).
Factor1 yd = 0.5 ftm
Converter
yd
Accepts numbers or expressions, e.g. 150 + 14.7
Result
ftm
Rendered to 6 significant figures.
Formula
Formula
ftm = yd × 0.5
Multiply any value in yards by 0.5 to obtain the value in fathoms.
Worked example
Convert 20 yd to ftm.
- 01Start with 20 yd.
- 02Multiply by the conversion factor: 20 × 0.5 = 10 ftm.
Result20 yd = 10 ftm

FAQ
What is the conversion factor from yd to ftm?
1 yd equals 0.5 ftm. To convert, multiply the value in yards by 0.5.
How do I convert 1 yd to ftm?
1 yd = 0.5 ftm. For any value, multiply by 0.5.
How do I convert ftm back to yd?
Divide by the same factor — or equivalently, multiply by 2. So 1 ftm = 2 yd.
When would I need to convert yard to fathom?
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).
