There is a new advanced version: vernier cliper (inch/mm mode, dial mode, measure inner/outer diameter and depth) 2010 Jan. 17 updated.



    This java applet shows you how to read the vernier scale on Vernier calipers.
    To observe how the scales are read, click in the "checkbox" by SHOW and drag the lower scale left or right to observe how the measurement is determined.
    Notice that the value for the upper scale is determined by where the 0 on the lower scale lines up with the upper scale and the number on the lower scale is determined by finding which mark on the lower scale best lines up with ANY mark on the upper scale.
    To test your ability to read a measurement, leave SHOW unchecked and then drag the lower scale left or right.

    The applet will wait for you to enter a value into the TextField and will then tell you whether your answer is correct.(After you type in an answer, press Enter.)
    Thanks goes to Mary Ball for rewording the instructions.



    This is another applet to help you understand how it works.
    You can drag the lower box or use the slider to see the gap between those boxes at different level.
    It is the gap which give us higher precission!

I would like to learn from you. How did you write the animated
programmes e.g. vernier calipers. Very interesting.

I would like to commend you on a wonderful site. The Vernier site is informative and
fun. I wanted to get your permission to link to your Vernier from a Cumberland County
Educational Physics course website. It was suggested to us that we get permission to
link to any sites so that we don't infringe on any copyright laws. I appreciate your hard
work.. You can respond to cmclean@webacademy.net
Thank -You for your time.

Dear Dr. Hwang,
  I have used some of your physics applets and I find them to be excellent.
Well done! At the moment in the Physics Department we are making changes to
our first year physics labs and would like to include your Vernier applet
in one of the labs in order to help the students learn to read a vernier
scale properly. Is is OK if we include the applet in one experiment?
Thanking you in advance,

Yours Sincerely,

Dr. Cathal Flynn

I really appreciate your site. I needed to brush up on my vernier caliper readings for a new job. Thanks

Hi Assoc. Prof. Fu-Kwun Hwang,

i am a Physics teacher from Singapore. I started using your applets in a Junior College and find them interesting and helpful for my students to visualise Physics concepts.
presently i'm teaching in a secondary school. i've set up a site at www.angjl.per.sg/Deyi.htm and i would like to have your permission to include links to applets in your site - begining with Vernier and Vector Addition.

thanks and best regards :)

Gentlemen:

Many thanks for your very helpful site describing the method of reading the
Vernier caliper.

I recently purchased a Starrett Vernier caliper on Ebay which is in
excellent condition and
although I thought I knew how to "read" the instrument I was not certain.
Your site was a
great help in assisting me to confirm what I already thought was the correct
method.

Many thanks to you and Mary Ball for the clear and concise instructions.

Sincerely,

Taylor Mullaly

Dear Mr. Hwang,

I have found your Vernier caliper program very useful for checking machine operator knowledge of use the caliper. Also we've organized a measurement training for our production personnel in which we had used the program to check their skills. Thank you very much for your efforts in spreading the physics all over the world!

Kind regards

Me dirijo a usted solicitandole información acerca de este interesantisimo applet que nos representa un vernier y me informa de una forma completamente didactica ,su manejo.

Actualmente, mi hija tiene interes por aprender el uso de esta herramienta aun cuando se encuentra en educacion básica y no encuentro la forma de hacerle llegar este conocimeinto.

Por lo que el programa referido es lo mejor que he encontrado, informeme cual es el precio de este apple y si necesito algun tipo de licencia para usarlo con mi hija y con quien  necesite esta informacion
