a micrometer is a very accurate measurement tool, good advantage for precise work-0.01mm increments.
they are limited in range IE 0-25mm, 25-50mm, 50-75mm etc so selecting correct size range and screwing up to size adjustment can be time consuming- say if you are constantly changing from 5mm to say18mm means lots of winding in and out
major disadvantage is i use them at work - so means I'm AT work
major advantage is i make my parts "on size" so i can still go to work tomorrow.
There is no difference both are same

Well you actually answered your question yourself. You use the Micrometer to achieve a "precise and accurate measurement".
Has zero error.
the inventor of micrometer screw gauge is William Gascoigne.
To measure the thickness of a thin piece of wire we have got the instrument called the wire gauge. The thickness of a thin piece of wire is measured in mm.
The ratchet is a device which applies a pressure by slipping at a predetermined torque and thus prevents the spindle from moving further.
12 gauge is thicker than 14 gauge.
Bourdon's tube pressure gauge cannot be used to measure negative pressure. This is because absolute pressure must be measured and the Bourdon gauge only indicates the gauge pressure.
to cheak the diameter of something
both are used in accurate measuring in a wide range of environments
The caliper and micrometer use a dial or digital readout to measure the distance between the tips. The tolerances of these tools can be under .001 inch, making them extremely accurate.
A "depth gauge micrometer" is used by engineers. A depth gauge micrometer is a precision instrument used to measure various depths of different items.

A micrometer (or micrometer screw gauge) measures the volume of a screw.
A micrometer , sometimes known as a micrometer screw gauge, is a device incorporating a calibrated screw used widely for precise measurement of small distances in mechanical engineering and machining as well as most mechanical trades, along with other metrological instruments such as dial, vernier, and digital calipers. Micrometers are similar in use to vernier calipers but are more precise although the modern digital caliper has blurred the distinction between them.A micrometer is also used to measure the diameter of very small objects that a vernier calliper can't measure for example a screw or a piece of wire.This instrument is mainly used by mechanics.
Insturment used to measure the diameter of a string. A micrometer works just fine and is more accurate than a typical string guage which has calibrated slots.
Verniers give you a less accurate approximation of the thickness, whereas a micrometer can give a more accurate measurement, often by 100 orders more accurate.
The zero error in the vernier calipers and micrometer screw gauge when the O mark on the main scale is not in line with the pointer.
Gauge block.
A micrometer screw gauge is commonly known as a micrometer. This is a form of calipers used for measuring small dimensions. Screw gauge in extensively used in the engineering field for obtaining precision measurements. The article describes the principle and main parts of a basic micrometer screw gauge.
