Question

Discuss with examples how people measured length in ancient times.

Answer 1

In ancient times, people used different body parts to measure length.
Examples:
Hand span: It is the distance between the tip of the thumb and the tip of the little finger of a fully stretched hand.
Cubit: It is the distance between the tip of the middle finger and the elbow.
Fathom: It is the length of the outstretched arms.
However, these units were not reliable, so people realised the need for standard units.
