Unit Conversions

Postby DTingey_1C » Sun Oct 06, 2019 8:45 pm

Do we need to memorize all of the different prefixes(giga, kilo, nano, ect.)? Or will it be given to us on a test? If so do u have any easy ways to memorize them? Thanks.

Hey DTingey_1C!

I'd recommend using flashcards associate these unit prefixes to the actual values of each one. :D. It helped me so much in high school.

Because we went over them in lecture, I would definitely memorize them, especially for conversions. I think the only thing being given to us is the formula sheet which can be found on the class website under "Constants, Equations, PT".

Hope this helps!

I would suggest to at least memorize the more common ones such as kilo, milli, and nano. However, memorizing all of them would also be useful just in case. I also don't believe they will be given on the exam. As for an easy way to memorize them I would suggest either making a quizlet or make paper flashcards. Hope this helps!

I don't think the unit prefixes will be tested directly on the test, but it might come up in the questions (ex. How many molecules are there in 56 mg of...) I would recommend finding a mnemonic that corresponds with each prefix. There's a lot of them online so try finding one that's easy for you to remember.

Hi,

An easy way I memorize some of the basic prefixes is “King Henry Died By Drinking Chocolate Milk” K(ilo) H(ecto) D(eca) B(ase) D(eci) C(enti) M(illi). Basically, as you go down the line, the units progressively get smaller (1 kilo = 10,000 of the base or 10^3, 10^2, and so on until you reach Milli (10^-3)), and it just helps to memorize how much each unit is when converting. While this doesn’t address some of the prefixes (like giga) it’s definitely helped me with the basic ones. I hope this helped a little!

I believe that we should know the conversions as it will help with the efficiency of our test taking.
