Meters to Fathoms formula
The factor from meters to fathoms is 0.546806649.
ftm = m × 0.546806649
Why this factor: the meter and the fathom are both defined against the meter, so dividing one definition by the other gives 0.546806649 directly. Both definitions are set out in full below.
To go the other way, divide by 0.546806649 — or use the Fathoms to Meters converter, which is the same calculation reversed.
Worked example
Start with 12 m. Multiply by 0.546806649 to get 6.56168 ftm.
12 m × 0.546806649 = 6.56168 ftm
The converter above does this for any value you type, in either direction.
What is a meter?
The meter is the SI base unit of length — the reference every other length unit is now defined against.
Definition: Since 1983 the meter has been defined by fixing the speed of light in vacuum at exactly 299,792,458 meters per second, so a meter is the distance light travels in 1/299,792,458 of a second.
Where it is used: Universal in science, engineering and everyday measurement everywhere except the United States.
What is a fathom?
A fathom is six feet, the traditional unit for water depth.
Definition: Six international feet, so exactly 1.8288 meters.
Where it is used: Nautical charts, depth soundings, and anchor and cable lengths.
Meters vs Fathoms
The meter is an SI unit while the fathom is a specialized unit. That is why the factor between them is not a round number: the two systems were defined independently and only later tied together by exact agreement.
