2. Micrometer (device) - Wikipedia

   en.wikipedia.org/wiki/Micrometer_(device)

   Animation of a micrometer in use. The object being measured is in black. The measurement is 4.140 ± 0.005 mm. Micrometers use the screw to transform small distances [9] (that are too small to measure directly) into large rotations of the screw that are big enough to read from a scale. The accuracy of a micrometer derives from the accuracy of ...

3. Bore gauge - Wikipedia

   en.wikipedia.org/wiki/Bore_gauge

   An inside micrometer or vernier bore gauge measures a bore directly. The gauge has three symmetrical anvils that protrude from the gauge body that are connected to the dial or micrometer mechanism. As the knob is rotated it moves the anvils in or out with respect to the measurements.

4. Orders of magnitude (length) - Wikipedia

   en.wikipedia.org/wiki/Orders_of_magnitude_(length)

   The Earth-Moon orbit, Saturn, OGLE-TR-122b, Jupiter, and other objects, to scale. Click on image for detailed view and links to other length scales. Scale model at megameters of the main Solar System bodies. To help compare different orders of magnitude, this section lists lengths starting at 10 8 meters (100 megameters or 100,000 kilometers or ...

5. Calipers - Wikipedia

   en.wikipedia.org/wiki/Calipers

   Inside small jaws: used to measure the internal diameter of an object (like a hollow cylinder or pipe). Depth probe, or depth rod: used to measure depths of an object (like a small beaker) or a hole. Main scale (metric): marked every millimeter and helps to measure length correct up to 1 mm. Main scale (imperial): marked in inches and fractions.

6. Gauge (instrument) - Wikipedia

   en.wikipedia.org/wiki/Gauge_(instrument)

   a device used for measuring holes. Hole gauge [3] used to gage internal dimensions of bores that are either too small in diameter for an inside micrometer, and have greater economy than a bore gage or other precision internal gage. Caliper: a device used to measure the distance between two opposing sides of an object. Center gauges and fishtail ...

7. Hook gauge evaporimeter - Wikipedia

   en.wikipedia.org/wiki/Hook_gauge_evaporimeter

   The measurement is taken by turning the knob to lower the hook through the surface of the water until capillary action causes a small depression to form around the tip of the hook. The knob is then turned slowly until the depression "pops," with the measurement showing on the micrometer scale.

8. Micrometre - Wikipedia

   en.wikipedia.org/wiki/Micrometre

   The micrometre (Commonwealth English as used by the International Bureau of Weights and Measures; [1] SI symbol: μm) or micrometer (American English), also commonly known by the non-SI term micron, [2] is a unit of length in the International System of Units (SI) equalling 1 × 10 −6 metre (SI standard prefix "micro-" = 10 −6); that is, one millionth of a metre (or one thousandth of a ...

9. Gauge block - Wikipedia

   en.wikipedia.org/wiki/Gauge_block

   In use, the blocks are stacked to make up a desired length (or height). Gauge blocks were invented in 1896 by Swedish machinist Carl Edvard Johansson. [1] They are used as a reference for the calibration of measuring equipment used in machine shops, such as micrometers, sine bars, calipers, and dial indicators (when used in an inspection role ...
