Dear Mr Fu-Kwun Hwang,

  That sure is another great applet, but I hope that it can be improved so that it can be more similar to the vernier caliper one, in which we are able to adjust it and key in the readings.
  Furthermore, I really hope that there is an applet on how to read positive or negative zero error for faulty micrometer screw gauge and vernier caliper.
  I greatly appreciate your work as they really help out a lot.  ;DForgive me for asking so much ;D

Thanks a Million!
