About Fathom
The fathom is an imperial/nautical depth unit equal to 6 feet (1.8288 meters). It is common in marine contexts and charted water depths.
About Feet
Feet are imperial and US customary units of length; each is exactly 0.3048 meters. Twelve inches make one feet; feet are common in construction and human-scale dimensions.
How to convert fathoms to feet
1 fathom is equal to 6 feet:
1 fathom = (1.8288 m ÷ 0.3048 m) ft = 6 ft
Each fathom is defined as 1.8288 m and each feet as 0.3048 m, so one fathom equals 1.8288 ÷ 0.3048 ft = 6 ft.
Let d(fathom) be the numeric value of the same length measured in Fathom (fathom), and d(ft) the value in Feet (ft). Then:
d(ft) = d(fathom) × (1.8288 / 0.3048)
Equivalently, divide by how many fathom fit into one ft (meters per ft divided by meters per fathom):
d(ft) = d(fathom) ÷ 0.16666666666667
Or: feet = fathom ÷ 0.16666666666667
Examples
Example #1: Convert 20 fathom to feet
20 fathom = 20 fathom × (1.8288/0.3048) ft = 120 ft
20 fathom = 20 fathom ÷ 0.16666666666667 = 120 ft
Example #2: Convert 50 fathom to feet
50 fathom = 50 fathom × (1.8288/0.3048) ft = 300 ft
50 fathom = 50 fathom ÷ 0.16666666666667 = 300 ft
Summary
To convert Fathom to Feet, multiply the value in fathom by the ratio of meters per fathom divided by meters per ft. Equivalently: value_ft = value_fathom × (1.8288 / 0.3048). Numerically, 1 fathom equals 6 ft.
Relationship context
Both units belong to US customary / imperial length. Conversions often use simple ratios (for example inches and feet), while miles relate to yards and feet through fixed definitions. The numeric factor used here is traceable to the international inch (0.0254 m) and related definitions.
