A screw gauge works on the principle of screw. This screw principle helps to convert smaller distances into larger ones by measuring the rotation of the screw. It amplifies the smaller dimensions and this converts into larger ones. When we rotate the screw, there's a linear movement of the main scale.

Why does micrometre screw gauge work the way it does?
the screw gauge is an instrument which is used to measure length of an object.... the least count of an screw gauge can be found as follow.... l.c= pitch of the screw gauge no of divisions on main scale
What is the Difference between screw gauge and spherometer?
The difference between screw gauge and spherometer is that spherometer can measure the dimensions of spherical surfaces but screw gauge cannot
Why the instrument is named Screw gauge?
The instrument is called a screw gauge, or more often a micrometer, because it uses a screw to amplify a very small movement so that it can easily be read. The heart of the screw gauge is a very accurately ground thread, usually of 0.5mm pitch, so that the axial movement of the screw corresponds to a much larger movement of a barrel which carries a scale. The instrument can be difficult to read because two readings have to be added, one measuring to 0.5mm the linear motion of the screw, and the other on the barrel giving the 1/100 ths. To some extent this instrument has been superseded by the electronic digital version, which does not incorporate a screw thread. A different gauge, called a thread gauge, comprises a set of metal blades with serrated edges which can be used to identify different screw threads by matching the right blade to the thread by trial and error.
Why is the instrument called a screw gauge?
Because it can measure gauge of wire and has screw type structure.
Why is screw gauge commonly called as micrometer screw gauge?
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.
Who discovered screw gauge?
the inventor of micrometer screw gauge is William Gascoigne.
What instrument measures the volume of a screw?
A micrometer (or micrometer screw gauge) measures the volume of a screw.
Why ratchets are used in screw gauges?
Ratchets are used to prevent extra pressure on the screw in the screw gauge.
Inventor of screw gauge?
The screw gauge was invented by William Gascoigne around the year 1638. Gascoigne was a renowned astronomer and mathematician from England.
What does a standard screw pitch gauge measure?
what does a standard thread gauge measure
What is the principle of pressure gauge?
pressure gauge works on hooks law principle ,when we applying pressure in end connection of the pressure gauge ,the same pressure operating at end of the bourdon tube.
