The are used for making measurements that are accurate to a hundredth of a millimetre.

A Vernier caliper is quite accurate and idiot proof. Part of its accuracy lies in its general ease of use.
Vernier calipers are in use in machine shops throughout the world. Of course, they are gradually being replaced by digital calipers but, plenty are still in use in England.

I guess it is found by vernier as it works on vernier theory -Manasa
Because they were invented by Pierre Vernier in 1631.
I would use vernier callipers.
where on the vernier caliper would you read to obtain the vernier scale reading
First we keep the body in between the jaws of the caliper. Then we note the main scale reading and then vernier coincidence. Vernier coincidence is to be multiplied by the least count of the device. This is added with the main scale. That will be the required value of the dimensions of the object.
Very little, the screw gauge checks the pitch of threads while the vernier caliper is use to accurately measure distances.
