Petameter

A petameter (Pm) is a unit of length in the metric system, equal to 1 quadrillion meters (1 petameter = 10¹⁵ meters). This unit is extremely large and is used mainly in astronomy and theoretical physics to describe vast distances, such as those between stars or galaxies. For example, one petameter is about 105.7 light years. Since it measures such enormous distances, the petameter is not used in everyday life or common scientific applications—it’s mostly used in discussions about the scale of the universe.

Fathom

A fathom is a unit of length traditionally used to measure the depth of water. It equals 6 feet or approximately 1.8288 meters.

Originating from the Old English word fæðm, meaning "to embrace" or "outstretched arms," the fathom was based on the average distance between a person's outstretched arms. It has been widely used by sailors and navigators to estimate sea depths and underwater distances.

Key facts:

1 fathom = 6 feet
1 fathom ≈ 1.8288 meters
1 fathom = 2 yards

Though modern sonar and electronic instruments now measure depth more precisely, the fathom remains a traditional unit in nautical contexts, especially in maritime charts and historical references.
