How to use/read a micrometer?

Answer 1

the whole numbers are .100" and the lines after it are .025" each. the numbers on the dial are .001" each. for example, if it stops on the third line after the number 5 and the line on the dial corresponding to zero points to a 12, you reading would be .587" because it is .500 plus .075 plus .012.

Answer 2

Well, if your micrometer is an old-fashioned one like the type that is found in school labs, it works like this. It appears like a c-shaped clamp with a knob that can be turned. The reading is a combination of two things -- as you unscrew the knob, it uncovers graduations that you can read on the shaft. Second, there are finer graduations that give a fraction of a turn marked around the end of the knob. The two together are the reading. Now about STYLE. Always gently close the micrometer on the thing you are measuring. First, gently close it empty and record the reading. It ought to be zero but might not be if the micrometer has had some use. Now measure your object and subtract the zero reading to get the correct reading. You are now a pro.

I assume you are refering to an old standard micrometer, if you have enough money you can buy electronic ones.
You start by zeroing the micrometer, if it has a spring screw you tighten till this clicks - then it stops tightening & do not try to force it or you will distort the internal screw system. otherwise you always tighten it to exactly the same pressure - changing pressure will cause differences in older or cheaper micrometers.
You take the reading. if it is not on zero write down the value. You read the value from the scale that looks like a ruler & I assume you can read a ruler, but decimal point is the one that you use the little 10 devisional markings to determine. This scale is 9 units devided into 10. You look at the two scales & see which of the 10 scale markings is exactly opposit another marking.
Viz. the zero is not exactly on zero, it is a little more, but not onto the next mark. you look allong the 10 devision scale and see that the allignment of the lines on the main scal & the 10 devision scale changes as you move down the scale, the first & last line will be the same relative to the main sacle , but one of the lines within the 10 scale will be exactly (or the closest to) one of the line on the main scale. the number of that line is the next decimal . viz. if its the 4th line form zero, then the value is 4

Answer 4

You open the gap on the tool and put your object in the gap.
Close the gap and read the scale.
Depending on the type of micrometer, the scale is different.
A digital micrometer obviously gives you the measurement on an LCD screen.
A dial type gives you the inches and tenths on the slide and the hundreths&thousandths on the dial.
The traditional gives you the inches/tenths on the barrel and the smaller fractions on the rotating part of the handle.
