Why is miles used instead of fathoms?

Different measurement systems serve different purposes. Miles is standard in specific fields; fathoms is used elsewhere. Both persist due to historical convention and standardization.

How do I estimate fathoms to miles without a calculator?

The conversion factor is roughly 0.001136. For high precision, use a converter—these units don't have simple mental math equivalents.

When would I need to convert fathoms to miles?

When working across different professional fields or measurement systems. Engineers, scientists, and technicians frequently receive data in one system but need to report in another.
