Is measurements can be exact?
They cannot be because of errors that can be made by the measurer, calibration of instruments.
Would taking measurements of the same object several times and then averaging them give a more accurate measurement?
Generally, yes, because the averaging removes the effects of random errors in the measurements. However if your measurement technique has biases, these will not be removed through averaging and the averaged result will be biased.
Why do you need standard measurements?
We need standard measurements because it helps us to find the measurements of things.
What are the different kinds of measurements?
nonstandard and standard measurements...
Is measurements a adverb?
NO!!! 'measurements' is a plural common noun.
