Frequently Asked Questions
-
What is a fathom used for?
-
A fathom is a traditional English unit measuring length, mainly used for expressing water depth and lengths of ropes or cables in nautical fields.
-
Why use US survey inches instead of regular inches?
-
US survey inches are legacy units historically utilized in geodetic control, cadastral surveys, and mapping in the United States, important for interpreting older survey and land records.
-
Can this converter be used for modern engineering measurements?
-
Yes, it helps convert legacy units into more current measurement systems, although US survey inches are mostly replaced by international units in contemporary practice.
