btw- watch your grammar as well for the other placement test- not “doesn’t” but "don’t in your opening sentence.
Math is not a units of measurement (inch/cm…) but ability to use precalculus math. Look at the UW website for info on the skills tested. btw- in science one uses metric units so US students should be familiar with both. Students taking HS calculus may want to brush up on their more basic math before the test. It would be bad to place into a remedial math class because of forgotten knowledge on a test.
