The most common varieties of depth micrometers read in increments of one thousandth of an inch (.001″) or one ten-thousandth of an inch (.0001″). The process of reading a measurement from either type is similar. Along the sleeve of the depth micrometer will be graduations similar to a ruler.

What is a depth micrometer used for?
A depth micrometer is used to measure the depth of holes, slots, counterbores, recesses, and the distance from a surface to some recessed part. This type of micrometer is read exactly opposite to the method used to read an outside micrometer. The zero is located toward the closed end of the thimble.

How are the graduations read on a micrometer depth gage?
The graduations at every fourth interval are most often numbered 0, 1, 2 and so forth. These numbers represent . 100″ or one hundred thousandths of an inch. If using a depth micrometer with a 1-2″ rod, the graduation marked 6 would correspond to a measurement of 1.600″.

What's a depth micrometer?
A depth micrometer is a gauge used to measure the depth of holes, slots, and recesses. Depth micrometers feature a measurement rod that is inserted into the hole that needs to be measured. The rod is slowly lowered until it reaches the base of the recess.
What are the numbers on a micrometer?
Starting with the barrel scale, you will see a line of numbers across the barrel of your micrometer. Each number on the barrel scale represents 0.100. When looking at the barrel 1=0.100, 2=0.200, 3=0.300, and so on. Each of the tick marks between the bigger numbers on the barrel is equal to 0.025 or 25 thousandths.

How do you read a .0001 micrometer?
To read either a . 001" or . 0001" micrometer, you place the material to be measured between the anvil and spindle, and then turn the ratchet until the spindle closes down and stops moving. Then you read the markings on the sleeve and thimble.
What unit do micrometers use?
As said before, the manufacturers etch the micrometers with either the imperial or metric unit system. It depends on the country where the micrometers will be sold. In fact, in the United States, for instance, most micrometers are sold with the imperial system (inch).
What is the scale on a micrometer?
In general, the micrometer has two main scales: the main scale (on the sleeve barrel) and the second scale (on the thimble). Today’s most micrometers, however, an additional vernier scale (on the upper side of the main scale) is added to improve the accuracy. A micrometer with an imperial system and vernier scale.
Why do you need to zero the micrometer?
Furthermore, you need to zero the micrometer first to check whether there’s zero error or not to gain a more trustable result.
Is reading a micrometer easy?
Reading a micrometer is not too difficult, but not as simple as we may think of, such as reading a tape measure. However, it takes some steps which need the users to get a bit educated first especially for the beginners. There require some multiplication and addition.
Can you read a micrometer manually?
Add both the measurements of small gauge and outer one to find the reading of dial indicator. Reading a micrometer manually is actually very enjoyable, especially once you have been familiar with. However, it may slow you down.
How to read.0001 micrometer?
To read either a .001" or .0001" micrometer, you place the material to bemeasured between the anvil and spindle , and then turn the ratchet until the spindle closes down and stops moving. Then you read the markingson the sleeve and thimble. In the case of a .0001" micrometer you wouldthen read the markings on the vernier scale to get the .0001"measurement.
What scale is used to read to tenths of a thousandth?
To read to one ten-thousandth requires an additional scale called the"Vernier" scale. The vernier consists of ten divisions, marked on thesleeve, Each graduation of the vernier scale on the sleeve, represents.0001".
What is a micrometer?
Micrometers (otherwise known as micrometer screw gauges) are essential measurement tools used by mechanical engineers, machinists, and workers in other technical trades. They enable workers to take extremely fine measurements which may be displayed in either imperial or metric formats.
Types of Micrometer
There are various types of micrometers available, each suited to varying uses and applications. Outside micrometers are one of the most widely used varieties, but inside and depth micrometers are alternatives that may be more appropriate for use in certain scenarios. Below are some of the most common types of micrometers:
How to Read a Micrometer
Micrometers are the ideal tool for the measurement of cylindrical and spherical-shaped objects. In order to use a micrometer, you should follow these steps:
Measuring Procedure
Situate the item whose length, diameter, or thickness is to be determined betwixt the rods (spindle and anvil).
What is A Micrometer Used for?
Because of its capability in providing accurate measurement, many work fields rely on the micrometer. It is widely used in metalworking, machinery, mechanical engineering, laboratory, home use, engine building, hobby (cartridge reloading), etc. all the things that need high accuracy.
Proper Use and Care for a Micrometer
Be sure to unlock the locking lever before attempting to revolve the thimble.
What is an inch based micrometer?
Inch-based and a metric based outside micrometers are precision instruments used to measure the thickness of parts from small washers to large brake rotors. They work the same and are similar in design.
How many divisions are there in a metric micrometer?
It has whole millimeters on the top and half-millimeters on the bottom. There are 50 divisions of .01mm on the thimble of a metric micrometer.
How many millimeters are in a sleeve?
Start with the six whole millimeters on the bottom, which equals 6.0 millimeters. Then add in the one .50 millimeters on the top of the sleeve; this equals 6.50 millimeters. Finally, add in the five .01 millimeters on the thimble for a total of 6.55 millimeters. Next.
