Chain to Fathom Converter

About Chain (ch) and Fathom (ftm) Units

The Chain (Gunter's chain) was fundamental in surveying the American frontier. Measuring 66 feet (4 rods), it's the length of a cricket pitch. Ten square chains make an acre. Modern surveyors still reference chains in legal descriptions, and the unit remains visible in rural road layouts across the US. The Fathom remains vital in maritime navigation, measuring water depth and anchor chains. One fathom equals 6 feet. For reference, recreational scuba divers typically explore depths of 10-20 fathoms (60-120 feet), while the Titanic rests at about 1,200 fathoms (7,200 feet) below sea level.
