When you need very tiny measurements.
Calibrating micrometers: For quick reference the supplied test piece can be used. For calibrating a micrometer, gauge blocks are used.
It can measure micrometers which are really tiny
Generally least count of micrometer varies instrument to instrument.. But common micrometers which are used in institute level laboratories have least count of 0.0001mm
I assume that you are enquiring about a 'micrometer', the precision measuring instrument, as opposed to a 'micrometre' (to use the British spelling), which is an SI unit for distance? I guess this sums up the problem with the US spelling!A micrometer has no particular disadvantages -it does exactly what it is designed to do. I suppose you could say that you have to be taught how to read a micrometer is a 'disadvantage', but this is true for most analogue instruments. However, there are digital micrometers which overcome this difficulty.
Slip gauges (also known as gage blocks, Johansson gauges, or Gauge blocks) are precision ground and lapped measuring standards. They are used as references for the setting of measuring equipment such as micrometers, gap gauges, sine bars, dial indicators (when used in an inspection role). They are available in various grades depending on their intended use. · Calibration (AA) - (tolerance +0.00010 mm to -0.00005 mm) · Reference (AAA) -high tolerance (± 0.00005 mm or 0.000002 in) inspection (A) - (tolerance +0.00015 mm to -0.00005 mm) · workshop (B) - low tolerance (tolerance +0.00025 mm to -0.00015mm
Micrometers are mostly used by engineering personnel: Machinists, technicians, toolmakers, NC operators, quality inspectors, etc. Micrometers can also be used in laboratories by scientists.
Google calculator can be used for this - type your question into the google seach box.The returned answer is:424 nanometers = 0.424 micrometers
One tenth of 4200 micrometers is 420 micrometers.
By unit of length and distance and conversion ,we can say that Micrometers are used to measure micro particles like molecules and atoms in an element or a substance.
There are 64,000 micrometers in 64 millimeters. 64 millimeters x 1000 micrometers/1 millimeter = 64,000 micrometers 1 millimeter = 1000 micrometers
17,075,270,000,000,000,000,000,000 micrometers
25,400 micrometers
There are 1,000 micrometers in one millimeter.
1m = 1,000,000 micrometers 100 micrometers x (1m/1,000,000 micrometers) = 1 x 10-4m, or 0.0001m
In micrometers: about 200 micrometers.
6000 micrometers
325000 micrometers
