Question

any suggestions on how to remember measurements ?

Answer 1

Memory, as a study in mental capability, is individual, and there are a lot of techiniques, some of which appeal to different personalities. You could try mnemonics for standard measurements. Repetition and familiarity work best with raw data.

Answer 2

Formulas work best for me by remebering proofs of their derivations. In case I forget a formula, I can derive it again. That might sound inefficient, and granted it is often. But a logical progression in seeing how a formula is derived will help in remebering.
