How to read a fractional inch based vernier caliper without writing in paper (Shortcut Method)?

in #vernier5 years ago (edited)

Solving the fractional inch based unit in the vernier caliper is so easy when writing in any piece of paper. But it is also easy to read it orally and takes little practice to master. And how?

Refer to the image below as an example (credits to the owner).

If you already know how to read in the metric scale (mm or cm based unit), try to solve in the imperial scale.

Here's our reading in the imperial scale.

Main scale: 1 15/16 ''
Vernier scale: 5/128 ''

Now solve orally:

First ignore the main scale's whole number, which is 1.

Next rewrite the main scale: 15/128 (Because the Least Common Denominator or LCD is 128).

Multiply 15 by 8 and answer is 120 (Multiplied by 8 because LCD divided by 16 equals 8).

Next Multiply 5 by 1 and answer is 5 (Multiplied by 1 because LCD divided by 128 equals 1).

Lastly, add the two numerators (120 + 5 = 125), include the whole number in the main scale (1) and our FINAL ANSWER is 1 125/128 ''.

Still confused? Here's how I solved, written in a paper with few explanations:

Now we know how to solve the fractional inch based unit in the vernier caliper orally.

If you have any issues, difficulties or violent reactions regarding with my solution, please take any time to ask me, or correct me if I'm wrong. And don't forget to resteem. Have a nice day.

Regards.
