What is a unit of linear measurement equal to the length of a step or stride called?

A unit of linear measurement that corresponds to the length of a step or stride is called a pace. In measurement terms, one pace is typically defined as the distance covered by a full stride, which usually equates to approximately two steps. Paces are often used in various fields, including land navigation and surveying, as a simple way to gauge distances without the need for more precise measuring tools. In practical applications, measuring distances in paces can be particularly useful in outdoor settings, such as during search and rescue operations, where terrain and conditions may make the use of tools impractical.

The other options, while related to movement, do not correctly define a standard unit of linear measurement in the same way. A stride refers specifically to one step taken by a person, while a footstep can refer to a single foot placement. A yard is a distinct unit of measure that is not defined by the length of a person’s steps.
