how to use a vernier caliper

[Will_]

For anyone that says he's making it too complex, here's this: coming into the video I had zero experience using this instrument, and yet, here I am now with an ABSOLUTE understanding of this instrument.  I appreciated every word in this video. I even thought he was being terse- seemed like he had every word planned.  He'd make a great professor.  Thanks.

These all work the same way. The whole minor scale is one hash of the major scale, in this case the entire minor scale represents 1 mm of the major scale. Since it has 10 divisions, it is by tenths of a mm. Therefore, when you got the "7" from it that meant 7/10 mm. To add this to the 7mm from the major scale, you simply move the decimal one place left and you are at mm and you add them. There is no 14 or other numbers necessary. If you get a different Vernier, with this understanding of what you are looking at, you will know that the entire minor is one hash of the major and it will not confuse anyone.

Thanks for sharing this knowledge... In college they never taught with this clarity

who else have a physics 101 lab exam tomorrow

You've probably saved my physics and chemistry labs for this year!

You explained it better than my professor did.. Thank you!

Why was my comment removed? It wasn't in any way offensive, or negative, in my view.
I was merely making the point that reading the caliper is no where near as 'complicated' as you make it seem.
All that I was saying was that if you read in 'millimetres', in the example you give, the reading is very simply 7.7mm. The major scale indicates the 7mm, and the minor scale the 0.7mm, attached, following the decimal point. 
 And, in your second example, the measure is 'exactly' (as the instrument will allow) 17mm.
If your arithmetic was to demonstrate the mathematics underpinning Vernier's technology, then, with respect, it doesn't.
I'd be quite happy to explain this, but in this posting it is your prerogative, not mine.

Huge help for teaching my Forensics students how to use vernier calipers. Thanks!

Thank you. I have used a caliper when I was a young teenager, but obviously I didn't use the vernier scale. Now I bought a caliper, and I was about to send it back thinking the measurements were incorrect! - Thank you again

In my high school the teacher just keeps stuttering while he's trying to explain in his own weird way how it works. Thanks for sharing

Wait, why all the math with 14 and 0.05? The 0 on the minor scale goes beyond the 7 mm hairline. That means that we have 7.something mm's. Now look at the minor scale. It aligns with the 7 mark. That means 7.7 mm or 0.77 cm. No math, no calculations, just read the instrument...

I never used multiplication or anything (if I had to do it, I'd be frightened to ever touch a vernier - math was always my nemesis). Just took the number of the first number which comes before the 0 below, which is 7 and the second number which came to 7 (yes it lined up better than 6 in this example), so I know that the first number followed by the second, so it's 7.7mm indeed (or 0.77 cm).

For example I've just measured some copper wire I had lying around here. The first number was very close to 2, but not quite, so I know it's 1mm something. The next one aligned was at 8. So I know that my wire is 1.8 mm which is about 13 AWG.

Thanks DUDE, ur explanation was good, It helped me pass in my practicals!

[partheshsoni]

Hey nice sir. Atleast I had got the rough idea so that I can measure myself. Thanks God my Practical exams are saved!!

[GauriTyagimdma]

a day before my physics practical exam i had no idea wtf vernier is. this guy did in 5 minutes what my teacher couldn't do in a month

[djdancealone]

So the minor scale is only used when the 0 doesn't fall right on a number?

[premankr]

u explained much better than my school teachers ....thanks a lot sir

[hariprasadsubramaniam]

Excellent video. Thanks for the help. Studying for physics labs rn

[devminperera]

Thanks alot ! I understood vernier caliper well !

Might be a stupid question, but I'll ask it anyway. I understand how to correctly read the calipers, but I don't really understand why it works. Why do the measurement lines line up perfectly at the correct value? Could someone explain it to me?
