How to Read a Metric Micrometer
If you said 12 mm, you were right! Let’s try another one to be sure you’ve got it. Remember, you can click the picture to get a better view.
do you see 14mm? Good. Let’s move on. Remember that the barrel scale shows both whole and half millimeters? Take a look at the reading below to see if you understand how that works.
Did you say 11.5? See how there is a half mark showing? Great! You’ve got the barrel scale down.
Remember that we said this micrometer would measure down to the nearest 1/100 the of a millimeter? We can do this because of the thimble scale. The thimble scale has fifty marks around it. It also opens or closes the spindle by one-half millimeter each time it turns around. This means that each mark on the thimble scale equals 0.01 millimeters (that’s tiny!). Here is how it looks…
The best way to use the thimble scale is to remember that each mark represents two digits (the tenths and hundredths places). So look at a number like five as 0.05 , and ten as 0.10. This thimble scale above is reading 0.00 See how the zero lines up with the horizontal line on the barrel? You read the thimble scale at this line.
Do you have any practice sheets for reading a micrometer? (Your videos and reading a vernier caliper and micrometer were very helpful by the way)
Glad you found the videos helpful. We don’t have the practice sheets yet, but I’ll try to get some here soon. I’ll let you know when I do.
Its been more than a year and you still haven’t made practice sheets
Sir your videos are the best I may from India and it helps in diploma in mechanical engineering thanks sir
Quite good explanation & is very useful. Better if that were more .
Please include more practice sheets e.g. of screw gauge.
Like it a lot , hope you can add a practice sheers soon
I DONT UNDERSTAND ONE SHIT
Helped a lot!!
Excellent site giving learning tutorials in the simple way.
God bless you
Thank you very much this has helped a lot
Veeery useful! tHANK YOU!
Sir, can you provide us practice sheets? It will be helpful for us.
Very helpful in preparing for the Certified Quality Technician exam! Thank you!
