# Meters to Fathoms (m to ftm)

Source: https://www.unitconvertercalculator.com/length/meters-to-fathoms/

**1 m = 0.54680664916885 ftm**

One meter equals approximately 0.5468 fathoms. A fathom (6 feet / 1.8288 m) is about 1.83 meters, making 1 meter slightly more than half a fathom. This conversion is used when converting metric depth measurements to traditional nautical fathom charts.

## Units

### Meter (m)

The base unit of length in the International System of Units (SI). Used worldwide as the standard measure of distance.

### Fathom (ftm)

Exactly 6 feet (1.8288 m). Traditionally used to measure water depth in nautical contexts. Originally based on the span of outstretched arms.

## Background

A fathom is 1.8288 m. The Mariana Trench at 10,994 m is about 6,011 fathoms. Modern sonar measures depth in meters, but many nautical charts still show fathoms. Converting between them is routine in marine navigation.

## Good to Know

The meter is replacing the fathom on nautical charts worldwide. The International Hydrographic Organization recommends meters for new charts. But millions of existing charts still use fathoms, and many sailors still think in them. The transition from fathoms to meters will take generations.

## FAQ

### How many fathoms is 1 meter?

One meter equals approximately 0.5468 fathoms (slightly more than half a fathom).

### How many meters are in 1 fathom?

One fathom equals exactly 1.8288 meters (6 feet x 0.3048 m/foot).

### When is meters-to-fathoms used?

When converting modern metric depth measurements (from sonar or charts) to fathom-based nautical charts. Also in diving where some tables use fathoms.

## Non-Frequently Asked Questions

### Am I about half a fathom tall?

If you are about 1 meter tall, you are a child or a very short adult. Most adults are 1.5-1.9 m, which is 0.82-1.04 fathoms. A 1.83 m person (6 feet) is exactly 1 fathom. The fathom was based on arm span, which equals body height. You ARE your own fathom.

### How many swimming pool lengths make 1 fathom of depth?

A 25 m pool is about 13.7 fathoms long. But 1 fathom of depth (1.83 m) is about the shallow-end depth. So the pool is about 13.7 fathoms long and 1 fathom deep. Pools are flat. Oceans are not.

### Can I fathom a fathom?

Yes. The word 'fathom' means 'to embrace' (from Old English). A fathom (1.83 m) is literally the width of your outstretched arms. You can physically fathom a fathom by spreading your arms. When something is 'unfathomable,' it is wider than your arms can reach. The pun was always there.
