Must we know conversions (1 inch how many feet etc) for math?

<p>Anyone any idea?
I just tried a barrons question and i didnt know 1 inch was 1/12 of a feet! In my country everything's in centimetres and metres</p>

<p>No, you don’t need to know those.</p>

<p>Any necessary conversion will be given in the question itself, usually at the end. E.g., “(1 foot = 12 inches)”. [tinyrant]Yet another reason to stick to original SAT materials when possible.[/tinyrant]</p>

<p>However, you will need to know the number of minutes in an hour and, I believe, the number of seconds in a minute.</p>
