An outside micrometer is a precision measuring tool used to measure the dimensions of an object's external surface with high accuracy. It typically consists of a C-shaped frame, a spindle with a measuring face, and an anvil. The spindle is adjusted by rotating a thimble, allowing the user to take precise measurements in increments of 0.001 inch or 0.01 millimeters.
Calibrating an inside micrometer is more difficult because it requires access to the inside diameter of a cylinder or hole, which may not be easily achievable compared to the outer surface where an outside micrometer is used. Additionally, inside micrometers are more sensitive to temperature changes and require specialized procedures for accurate calibration.
I think you mean a drum micrometer, but I could be wrong. A drum micrometer is really a dial or digital caliper that checks the wear on a break drum on a car. The wear on a drum is on the inside of the drum and is checked by the ID (inside diameter) with the tool, a micrometer for the most part checks the OD (outside diameter) of something. The most accurate way of testing ID is with a spring loaded pin rod, then check the pin distance with a micrometer.
One micrometer is larger than one nanometer. One micrometer is equal to 1000 nanometers.
it is abbreviated with um
To find the least count of a micrometer in the imperial system, first convert the micrometer value to inches. Then, divide 1 inch by the number of divisions on the micrometer scale. This will give you the least count of the micrometer in the imperial system.

When the jaws should be measured in micrometers is used in its place.
Visual inspection with outside micrometer. They should not be glazed, pitted, or thinner than the allowable minimum as measured with the micrometer.
Calibrating an inside micrometer is more difficult because it requires access to the inside diameter of a cylinder or hole, which may not be easily achievable compared to the outer surface where an outside micrometer is used. Additionally, inside micrometers are more sensitive to temperature changes and require specialized procedures for accurate calibration.
A micrometer is equal to exactly 1 micrometer.
*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
You need to crack it open then measure the outside of it with a ruler in millimeters. OR you could use a micrometer.
