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.
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.
A kilogram mass and three metric measuring devices: a tape measure in centimetres, a thermometer in degrees Celsius, and a multimeter that measures potential in volts, current in amperes and resistance in ohms.
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.
No direct measurement to the tree's trunk or top is taken in the parallax Method. Three verticals method (formerly the triangle method) is a modification of the simpler parallax method. [39] It is possible to measure the height of a tree indirectly without taking any horizontal sweep angles, which can be difficult to obtain accurately in the field.
A measuring instrument for lengths: a typical tape measure with both metric and imperial units and two US pennies for comparison A measuring instrument is a device to measure a physical quantity . In the physical sciences , quality assurance , and engineering , measurement is the activity of obtaining and comparing physical quantities of real ...
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.
