A Chesterman tape measure. James Chesterman, a British metalworker, is credited with the invention of the first retractable tape measure in 1821. [6] His design consisted of a spring-loaded cloth strip with marked measurements, housed within a compact case. Building upon his prior design, Chesterman would patent the first steel tape measure.

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.

A gap (initially one inch, later 3/4 inch) between records allowed the mechanism time to start and stop the tape. Latency There was only a 1.5 ms delay for the stopped tape to reach its full reading or writing speed. Markers Aluminum strips were glued several feet from the ends of the tape to serve as logical beginning and end of tape markers.
A diameter tape (D-tape) is a measuring tape used to estimate the diameter of a cylinder object, typically the stem of a tree or pipe. A diameter tape has either metric or imperial measurements reduced by the value of π. This means the tape measures the diameter of the object. It is assumed that the cylinder object is a perfect circle.
A ruler with two linear scales: the metric and imperial.It includes shorter minor graduations and longer major graduations. A graduation is a marking used to indicate points on a visual scale, which can be present on a container, a measuring device, or the axes of a line plot, usually one of many along a line or curve, each in the form of short line segments perpendicular to the line or curve.

Handsaw Three old handsaws: A handsaw, according to Cambridge University, "a saw that is operated by hand rather than using electricity or a motor." [21] Files & Rasps Top two are files.
The Broselow Tape, also called the Broselow pediatric emergency tape, is a color-coded length-based tape measure that is used throughout the world for pediatric emergencies. The Broselow Tape relates a child's height as measured by the tape to their weight to provide medical instructions including medication dosages , the size of the equipment ...
For common tape measurements, the tape used is a steel tape with coefficient of thermal expansion C equal to 0.000,011,6 units per unit length per degree Celsius change. This means that the tape changes length by 1.16 mm per 10 m tape per 10 °C change from the standard temperature of the tape.
