Im assuming that the Venier caliber is used to measure diameter and the micrometer screw gauge is used for Thickness, is this correct ? and also when getting the value from the micrometer screw gauge you multiply the micrometer scale by 0.1 ,what is the value you multiply for the vernier scale ?

We multiply by 0.1 mm in caliper and 0.01 mm in micrometer i think.And yeah they are usually used in that sense.

We multiply by 0.1 cm in caliper and 0.1 mm(0.01 cm) in micrometer i think.And yeah they are usually used in that sense.

its o.1 mm in caliper and o.o1mm in micrometer...

I know this page is for sciences but does anyone have alll the english formats???

Oops sorry about that,haven't slept properly :/ dimagh nai kam kar ra

Thank you

There is also a formula in my physics book for this:

Upper point Temp = 60
Lower Point Length = 5 cm
Upper Point Length = 11 cm
Temp(c) = -10

Why apply a formula when you can easily do it this way.

Well, multiply.
I just add the values.

Because math is fun for some people.
and mathematical proof is powerful.

Alright, so how do we get the width exactly right in the magnification questions? For instance, question no 2 of June 2004. Can somebody show me as to how we get the right measurements. Width, precisely.

u make ur drawing of the exact shape but a more largerone....u measure the maximum length....make sure the ratio of increase in both vessels is equal.....then measure the length of the same plc in fig 2.2 and then put the lenght of u drawing as nominator and the actual size as denom....

Guidelines for magnification and drawing a large diagram; anyone?

y....maths way way way way better......although i do not get enough marks in math than in bio...i like maths more....
