Do we need to memorize all the units and conversions we learnt in class (deci, nano, etc) for the test this week or the midterms in class?

Conversions are very helpful to know especially when a units need to be converted to match SI units.

Considering that a few SI conversions (like nano) were given on the first exam, I'm not sure if they will also be provided on the midterms, but it's better safe than sorry to try and remember as much as you can!

Sometimes they will give it to you, but it is pretty easy and helpful just to memorize them.

I believe that the formula sheet we use in class is available somewhere online. Some of the conversions are provided on it, though it is certainly helpful to know them off the top of your head as well.

Although Test 1 contained all the unit conversions needed, I believe it will be safer and easier to memorize the main conversions especially for the midterm.

I think if there is one they don’t expect you to know, they will put it on the sheet. The ones you should know are the ones we went over in class though. Any other conversions that are semi-difficult should be put on the sheet.

It's very helpful to know the basic conversions, especially the metric system (because they're all multiples of ten). However, I believe that on the tests, Lavelle provides some of the conversions as a reference sheet.

I think my TA mentioned that just to be safe we should memorize them, in case they happen to be missing from the formula sheet.

It would be great to memorize them! There are a few that are used extensively in life-science applications, and it would be wonderful in my opinion to streamline our calculations by committing some of these prefixes to memory.
