A tape measure or measuring tape is a long, flexible ruler used to measure length or distance. [1] It usually consists of a ribbon of cloth, plastic, fibreglass, or metal strip with linear measurement markings.
A tape diagram is a rectangular visual model resembling a piece of tape, that is used to assist with the calculation of ratios and addition, subtraction, and commonly multiplication. It is also known as a divided bar model, fraction strip, length model or strip diagram.

A variety of rulers A carpenter's rule Retractable flexible rule or tape measure A closeup of a steel ruler A ruler in combination with a letter scale. A ruler, sometimes called a rule, scale or a line gauge or metre/meter stick, is an instrument used to make length measurements, whereby a length is read from a series of markings called "rules" along an edge of the device.

To measure the diameter of a tree, the diameter tape (diameter side facing user) is wrapped around the tree, in the plane perpendicular to the axis of the trunk at 4.5 feet (1.4 m) above ground (or 4.27 feet (1.30 m), depending on the location) . Where the number "0" aligns with the rest of the tape, the diameter can be read directly from the ...
Labelled diagram of the protractor head. The protractor head can be used for: Measuring and checking angles between surfaces, edges, and markings. Marking angles from an edge; Directly transferring angles, like a bevel gauge (sliding T gauge), to minimise measurement errors and inaccuracies.
A witness first saw the gun poking through a crack between the apartment door and the frame. There had been a knock and an eerie silence, then an attempt by two men to force the door open.
Good surveyors will keep track of any circumstance on the path that can influence the accuracy of the distance measured and either measure that portion with an alternative, such as a surveyor's tape or measuring tape, or make a reasonable estimate of the correction to apply. Surveyor's wheels are used primarily for lower accuracy surveys.
