A micrometer (or micrometer screw gauge) measures the volume of a screw.
The difference between screw gauge and spherometer is that spherometer can measure the dimensions of spherical surfaces but screw gauge cannot

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.
The least count of vernier caliper is 0.01mm while the least count of screw gauge is 0.001 mm. ... Difference between screw gauge and vernier caliper in tabular form. Micrometer Screw Gauge Vernier caliper It has a circular scale. It has a vernier scale. It rotates to measure the objects. It slides to measure the length.
*Micrometer have a rotary handle and whereas vernier have a slider. *Micrometer is for measuring diameters while vernier is for measuring inside & outside diameter as well as depth. *Least Count of Vernier Caliper is 0.02mm *Least Count of Micrometer is 0.01mm
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.
the inventor of micrometer screw gauge is William Gascoigne.
mild steel
both are used in accurate measuring in a wide range of environments
The distance between each line of the body is equal to 0.5 mm. Gauge the distance between each line is equal to 0.01 mm.
William Gascoigne invented it in the 17th century.
