This is a simulation for vernier cliper.
It can be used to measure outer diameter, inner diameter and depth with slider in different color.
Blue slider: change width of the outer diameter.
Green slider: change the inner diameter
Yellow slider: change the depth of the object.
You can drag objects need to be measures (blue and yellow).
Drag the vertical slider at the right to change the scale.
Click show to show measured value.

This is a great AppleT.
the most complete vernier caliper.

You can and should include this into your list for checking out too.

there are other good features to include.
your input field that you got me to understand how to make.
I like the app but it is unclear what the units are for each scale. I shouldn't have to assume that the top scale is inches and the bottom scale is mm. Please put some indication of the units on the diagram, because I tell my students to ALWAYS look for the units on the instrument.
Thank you for your suggestion. I just added the unit into the simulation.
This applet is awesome!
I would just like to point out that the units on the scales seem to have been reversed.
Would you please be more specific: please give me an example. Thank you!
I mean the inches scale seem to be marked in the mm, and the mm scale is marked in inches.
I also would like to embed these applets in my website. Are there any specific instructions for me to do so?
Thanks a lot for these!

When the above simulation in default state: (not in

The value will be shown in inch when
check-box is checked.
I just recently found this simulation and think it is very well done, and I hope to use it for training purposes at work. I have, however, found two errors that are beyond my ability to correct in order for it to be completely accurate.
First, any measurement taken above 1 inch in length only reports the correct values after the decimal place. Example: "d = 28.40 mm = 0.117 inch" which should read "d = 28.40 mm = 1.117 inch".
Second, when the simulation is set to Dial and measuring in metric the 0 line on the fixed scale is correctly positioned to be measured from the edge of the sliding jaw, but when you switch to inch mode the scale gets positioned the same as the default metric setting without the dial which makes the reading appear to be off by approximately 0.125 inches.

And for a free product, I agree it is much better than anything I could create. I was just curious if anyone else out there could fix those two minor errors. I can still use this for training purposes, as the dial portion isn't critical to me, and I can overlook the erroneous whole number portion of the reading as needed.
The above two bugs has been fixed now. Thank you very much!
