Yesterday Kevin (Grandpa love) was asking about how to read a vernier caliper. Most told him to get a digital caliper or this tool was not that accurate to read this small of a measurement.
I took this as many do not know how to read a vernier caliper because you can read very small readings with one. The one pictured is inches on top and millimeters on bottom. But the do make them inches on top and thousands of a inch on the bottom.
But lets look at the tool kevin has. Since he was adjusting a nut on a turnbuckle he would never get it precise to a thousands of a inch. So I informed him to get it close and let it ride. Down to 1/128 of a inch would be close enough.
So he was looking for 0.395-0.397 Since he had 128 scale I informed him that 50/128 is .390 and 51/128 is .398 So 51/128 would be close enough.
But how do you read 51/128 on the scale.
Here is how you read a vernier caliper. First you find 0 on the bottom scale and read the 1/16 line to its left. This picture shows 3/8 or 6/16. I think anyone that can read a ruler can get this so far. But how do you get it down to 128 of a inch.
Lets take 3/8 and bring it up to 128's 128 / 8 is 16 16 x 3 is 48 So 3/8 is the same thing as 48/128
Now we look at the small scale. You will notice the 2nd line is just a little past 1/2 And the 4th line is just a little before 5/8 This means we will want to use the 3rd line that is right on with 9/16 So since the 3rd line matches up on the 128 scale we will add 3/128 to our figure from above.
3/128 + 48/128 = 51/128 And that is how you read a vernier caliper down to 128th of a inch.
