Yardstick
A yardstick is a tool to measure distances up to three feet (a yard). Most yardsticks are flat wooden boards with black markings at regular intervals and metal tips. Many new yardsticks have imperial units markings on one side (three feet with inch and fractional inch) and metric units on the other side (one meter with centimeter and millimeter) on the reverse side.
Yardsticks are frequently used as pointing devices for posters and projections.
The term is also used metaphorically to mean any test or standard used in measurement or comparison.
