How to Read Micrometers

Here's a how-to video on reading both Inch and Metric micrometers. I also point out some of the pitfalls and common mistakes that I've noticed time and time again with my beginning machining students.

@@DenverLoveless .01 mm = 0.0003937008 in (so if you are rounding up, you would be losing that precision) This is similar to comparing precision of Celsius vs. Fahrenheit markings on the same thermometer. These are just different scale measurements.

[@bernieshort9774]

I am an engineer and have been reading mic's for years. You have made this task much easier for many I would assume, especially in this digital age where most digital callipers are not as accurate as micrometers. First class video.

This was a remarkably clear and concise explanation.

A very helpful video to reference for my refresher course before my United Airlines interview the other day. Excellent work.

[@cannonfodder4376]

​@Roberto Garcia Tech Ops or backstop jobs. If you work on landing gear or engine overhauls you definitely will be using micrometers.

Thank you so much Stuart, I could have used this a week ago while starting a new job. My "trainer" gave me 30 seconds of training and said go for it and left me WAY confused. I know I'm better off now.

Great video. Just ordered a micrometer. Been realizing I needed one in my shop. They are definitely handy to have. My first job was at an automotive machine shop. I use to use them all the time. But that was 20 years ago. Kinda forgot how to do it. One watch of your video, it all came back to me. Keep up the excellent work man.

Thanks so much. I thought I’d watch as a refresher, then discovered how much I didn’t know / had forgotten.

[@iantheorem]

This is opening up a whole new world to me and is making me appreciate my grandfather more being that he was a master machinist and had many calipers like these laying around his shop

[@StuartdeHaro]

I'm glad you got something out of it. My grandfather also worked with machine tools, but unfortunately I didn't find that out until close to the end of his life. I always knew him as this grumpy guy who talked about jazz and the war all the time. It wasn't until I got a job as a machinist that he talked about his time at the power company doing maintenance machining. He had been retired my entire life, so I had never even thought about what he had done for a living. At least he and I got to share a little shop talk there at the end. Thanks for watching!

Thank you so very much for imparting this knowledge. Your method is so much simpler. One can only imagine how difficult the FAA General aircraft mechanic knowledge guide can be... Given the FAA wrote the material. A mystery solved.

[@spaceman081447]

I first learned how to read a micrometer in a junior high school shop class in 1962. For me, it was easier to remember that all readings are in 1/10,000ths of an inch. To use the instructor's first example: 0.5 in = 0.5000 in [500 ten thousandths] (4 decimal places) 0.009 in = 0.0090 in [90 ten thousandths] (4 decimal places) 0.0005 in = 0.0005 in [5 ten thousandths] (4 decimal places) TOTAL: 0.5095 in = 0.5095 in [5,095 ten thousandths] (4 decimal places)

[@thatoldbob7956]

No relation or any other connection that I’ll watch his stuff and he commented on some of mine. I have no equipment or editing ability as Tony has. Most likely I am twice of his age so I can show lots of old but some unknown by most people. I need time , energy and room to work. Your clear and precise explanation for important detail is appreciated. I have a mech. And a civil eng. but I am neither of them. I grew up in a steel shop of my gpa, learned the trade and became a structural engineer in steel structures only. Tony is toooo precise for me but producing enjoyable shows. Thanks again

As a lifelong CNC Machinist and supervisor, I've had to teach this to young trainees a gazillion times...they're lucky if they can grasp the math involved. Reading the mic is only half the battle! Applying the math will lose quite a few. Good explanation, wish they had this kinda video years ago.

Thanks Stu, I only use imperial or digital mics. I haven't used a metric, but I feel I get the idea now. It's odd how the scales are used differently, I guess because MM are just such smaller increments than inches. Thanks for clearing that up...I guess this is why you're a teacher!

P.S Metric micrometers are a lot easier to read, however are they more accurate? :-)

Thanks for watching! The metric mics shown in this video only read to .01mm, which is .0003937", but there are metric mics available that read down to .001mm with a vernier scale just like the inch mics shown. Of course, you can get mics of either variety in finer graduations if you look around.
