THE THREE STEPS OF MEASURING WITH A MICROMETER:
Clean the micrometer: Use soft cloth to wipe down the anvil and the spindle of the micrometer. Removing any dust or debris present on the measuring faces will ensure precise measurement.
Begin to measure: Place the object you are measuring against the micrometer’s anvil. Tighten the device until the spindle is firmly pressed against the object. If you need to prevent your thimble from turning use the locking lever or wheel to secure it in place. You can also fasten the frame on a micrometer stand to free up both of your hands if so desired.
Read the measurement: Follow the four step measuring process, noted in detail below.
HOW DO YOU READ MICROMETERS?
FOLLOW THIS SIMPLE FOUR-STEP PROCESS TO READ MICROMETERS:
how to read a micrometer
STEP 1: Read the sleeve measurement
STEP 2: Next, read the thimble measurement
STEP 3: Now read the vernier
The vernier will provide the ten-thousandths place of your decimal measurement.
STEP 4: Finally, add it up!
Add step 2 to step 1 (add your thimble measurement to our sleeve measurement), and then just "tack" step 3 (your vernier measurement) onto the end. As an example, if you're measuring something that is 0.1234", you'd find the .100 on the sleeve (step 1), the .023 on the thimble (step 2), and then you'd add . 023 to .100 for a combined .123. Then, you'd find .0004 on the vernier scale and just tack that onto the end.
TECH TIP: Sometimes, for people who are learning this, when you have .123, and you see the .0004 on the vernier scale, it's easy to misunderstand, leave out a zero (.004), add it to .123 and get .127. It's easier to understand if you forget about the zeroes and just put the number from the vernier scale onto the fourth place (the ten-thousandths place), at the end of the .123, to obtain the correct measurement of .1234.
MICROMETER MAINTENANCE & TECH TIPS:
Maintenance & Cleaning: Before use, gently but thoroughly remove oil, dust and dirt from the entire surface of the micrometer, taking care not to damage the measuring faces. Clean the measuring faces with a clean cloth before and after taking any measurements.
Calibrate When Necessary: When a micrometer is at its minimum reading, the horizontal line on the sleeve should line up with the ‘0’ on the thimble. If that is not the case, calibrate the micrometer by rotating the sleeve. Each micrometer comes with an adjusting wrench for this specific purpose. Verify the horizontal line on the sleeve lines up with the ‘0’ on the thimble before each use.
Micrometer Storage: When not in use, properly store your micrometer in an environment free of heat, dust, humidity, oil, and mist. If you have electronic (digital) micrometers, remove the batteries if they'll be stored for a long period of time.

Things like these are so simple and easy to explain like how this guy does but you have some people that dont wanna explain it like this
Thanks Isaac. I'm a pretty "simple" guy, so I try to explain things so even I can understand them. 😊
I just got job as a QC inspector and was never taught this at my previous job, since we used digital ones. This helps soo much. Thanks you, now i wont like like an idiot 😂😂
And those people that don't want to teach are the same ones that complain young men are not interested in trades.
Thanks for this. I'm going into machining and this is one of the tools I've never had hands on at home to learn, and in just a couple minutes I feel like I've already mastered it. Great explanation!
Thank you, JeSuisNerd. That's very encouraging, since that's what I was hoping to accomplish.
I start my very first day machining tomorrow.
how has it been going
@@TheBlessedFighterprobably died like we wish we could.
I’ve been told how to use these many times and only completely understood it now through this video, thank you so much!!!
Thank you, Monster8242. I'm glad it was helpful.
Best explanation I've seen definitely saving this video.
Thanks! We’re glad it helped you.
This is great I’m in a CNC program and this explanation is so clear.
Thank you, Mikal. I'm glad you found it to be helpful!
Thanks a million!! Friday, 3:30pm, just trying to make it happen!!🙏🙏
Thanks, TheDsFinest. Have a great weekend!
I'm getting my AMT certificate. Your videos have been a tremendous help. THANK YOU
WOW - Congratulations on getting AMT certified, Chris!!! And thank you for the HUGE encouragement! I'm so glad that you found them to be helpful.
Been awhile since ive used these and never used them much mainly calipers . The person who taught me the micrometer confused the hell outta me. So THANK YOU FOR MAKIN IT SIMPLE ❤
I'm so glad it was helpful, Alabama Heartbreaker.
I just started machining. You make this really simple. Thanks
It's so encouraging to know the video was helpful. Thank you, Christopher.
Thank you I’m going in to work tomorrow at 4am to recheck my numbers you saved my job if it wasn’t for you i would lose it because my numbers were fake
Thanks, Jacob. That's very encouraging to me. I do have to commend you for persevering, figuring it out, and making it right. Companies need more people like you.
Thank you. It's been a while and this was a great refresher. Very well put together video, my man. :)
Thank you, Kiltic Studios. You're very encouraging!
Watching this video after getting a ball micrometer. Super helpful. Thank you.
Thanks, Quadshot308. I'm glad it was helpful!
He's explaining it wayyyy different than i originally learned it. Nicee
Quick correction- at 7:05 you say that one tenth of an inch (0.100") at most machine shops would be called one hundred thousand of an inch when it would actually be one hundred thousandths of an inch (one hundred thousandth = 0.00001" one hundred thousandths = 0.100" small error when spoken, potentially catastrophic error in measurement) otherwise great video and simple easy to understand explanation of how to accurately read a micrometer.
Although .00001" is one hundred-thousandth (or it's "one" -- one hundred-thousandth), and .100" is one hundred thousanths, which is the equivelent of one tenth of an inch. I know - confusing, right?! Here's another way to say it. .00001 is one piece of something that was sliced into one hundred thousand pieces. .100 is one hundred pieces of something that was sliced into one thousand pieces. Does that make sense?
@@wonbythe1 I was just correcting the point in the video when he accidentally called 0.100" ( one-hundred thousandths) one hundred-housandth when he meant one hundred thousandths- that S on the end of thousandths literally means the difference between.1" and .00001"
Measuring tools are so cool!
THANK YOU ALOT.!!
You have helped me understand this since I will be explaining it to my technical class next week!
I was little worried, But now i feel more confident 😍
Thank youuuuuu!
God Bless You 🌹
Hi Ahmad. How exciting and encouraging it is -- to know it was so helpful. I also did one on how to reead calipers, just in case you might be interested in that one too. Our Lord, God bless you as well, Ahmad. Thank you.
Thank you for making this super consice and to the point. I especially liked the practical demonstration of measuring the washer at the end. I was trying to use a micrometer to measure something at work and had no idea what i was doing with them lol. I'm a maintenance mechanic, not a machinist but I needed to measure a small shaft (about .25") and the micrometer was all I could find 😅
Thank you, Tj. I'm glad it was helpful. Before you know what you're looking at on a micrometer, it can be pretty daunting. Reading them isn't really intuative, so once it's explained, it's actually not very hard at all.
Thanks a lot. Your explanation made it so easy to understand. I was pausing the video to try to get the measurements before you said them and I did!
Thank you, Nathan. GREAT way to train yourself to do it, and practice. Nice job!!!
Thank you for this explanation. I was ripping my hair off trying to understand machine shop lingo but now it makes sense.
Ha haaaaa -- Thank you, Ibti Uddin. I'm glad it was helpful, and I hope you still have some hair left. LOL!
Great video and explanations! I am using this video to share with my classmates in our Manufacturing Materials Processes class because it was so easy to follow and informational, thank you!
Thank you, Ashton. I'm glad you found it helpful.

Ok. I have a question if someone can help me out here. What if you only have a thousandths micrometer and it doesn’t go to ten thousandths. Should you go by what’s lower than the index line or above it?
I wouldn't use the "spinning" method.
Why not ?
@@deonlewis5318 It puts strain on the barrel, and the thread.
There's also the possibility of banging it on something.
Far better to hold the frame, and roll the barrel along your arm.
Great way to add undue stress to the precision bearings by spinning an unbalanced mass on its axis... that was just all around not good.
I appreciate your opinion, Scott. Thanks for your insight.
Affiliate link to micrometer in your hand would have been nice.
Can someone help ? What does it mean when it says “record your answer to the .0005 of an inch”
And the measurement is .300
Probably when you write your answer it needs to go that many zeros when you write? Like your answer would be .1585
You have to measure down to half a thousandth
Anyone else studying for a lab practical?
Hi Aseel. A lot of our customers are schools and students.
Me
Urdu translated..
write down the number will be easier
I wonder why it's called MicroMETER but here, in the video we are taught how to use it in imperial. Just a funny thought.
Crazy world, isn't it, TheFishingKit? Ha haaa Kind of like, why do you drive on a parkway and park on a driveway. LOL!
@@wonbythe1 only in America though :D
A meter was a measuring device before it was a metric unit
Micrometer in inches.
