How to memorize prefixes

Postby samanthaywu » Mon Nov 23, 2020 5:06 pm

Does anyone have effective strategies for memorizing the prefixes for units? (like mega- kilo- deca- milli-, etc.)

You just gotta Quizlet those out, I think that's the best way and it took me maybe 5 minutes/day for two days until I had them down.

For those, mini flash cards really helped me when I was learning them in AP chem. Our teacher actually suggested it and it turned out to be useful.

As said before, used flash cards! I like to make my own using quizlet or I use somebody else's quizlet

Lots of repetition and practice problems will help you over time. If you're still struggling approaching the final making a quizlet would be a great idea!

Try associating the prefixes with things you remember. For example I associate deca with decade.

I used to just memorize them by practice (repeating them out loud or through flashcards) or associating them with words that also contain that prefix. If worse comes to worst, the equation sheet will have a few conversion factors.

I just use flashcards or just memorize them straight up because many of them are used so often in all STEM based classes.

As others have said quizlet/flashcards are pretty helpful when trying to memorize the prefixes. Unit conversion problems help out a lot too. Good luck!

Before when I wasn't as confident with them, I would try to think of other words with the prefixes to help me (ex. decathlon, cent, millennium). If you can't come up with any, or if you have trouble memorizing them, I'm sure there are several mnemonics online that can make it easier.

I'd definitely suggest mnemonics for some of the less common ones but try to remember some of the more common ones.

I use the mnemonic King Henry Died by Drinking Chocolate Milk. K= kilo, H = hecto, D = deca, b = standard unit, D = deci, C = centi, M= milli. I hope this helps!!

Mine is pretty similar to the one mentioned before, but I use "Kings Hate Dragons Because Dragons Can’t Make Money" for Kilo, Hecto, Deca, Base, Deci, Centi, Milli, Micro.

I've heard the above mnemonics as well! But I think what is most helpful is to do as many practice problems as possible and review often. I hope this helps! Good luck.

When I took psychology in high school, my teacher said the best way to prefixes and other words is to come up with a goofy term for it, and studies have shown that mnemonics are greatly beneficial and actually work.

For me, a table was actually the most helpful for me! I used the table for every problem I completed until I was naturally doing it without checking the table because it became a force of habit! Maybe try to memorize them in order so you don't have to match them up individually, but you know the listing order!

Hi, mnemonics are definitely a great way to memorize these prefixes and constant repetition (although takes time) works well too!

I think quizlet is a good way to learn it and a good alternative to actual flashcards.

Hi, you can use flashcards, quizlets, or even mnemonics to help remember the prefixes.

I memorized it in high school through flash cards/quizlet, if that helps!

This may not be overly specific, but whenever looking at a prefix I'm unsure of, then I try to think of another word I know already that effectively contains the same prefix. For example, I know that a CENTury is a period of 100 years, so I can assume that a unit with the prefix centi- will relate to the base unit by a factor of 100, or 10^2. Unfortunately, learning which prefixes are larger or smaller than the base unit (i.e. a centimeter is smaller than a meter) came down to rote memorization for me, but the aforementioned strategy made the task of comprehending the prefixes' meanings far less daunting for sure. I hope this helps!

On a separate note, if you're worried about prefix memorization for the sake of doing well on one of the exams, I wouldn't worry to much. On the constants and equations sheet on Dr. Lavelle's website, all of the units that are likely to appear on an exam are listed as a measure of the base unit, albeit in the abbreviated form. For example, 1 nm = 10^-9 m. The only exception is that 1 liter is described in cubic decimeters. As long as you remember that 1 dm = 10^-1 m, everything else you might need is given to you.
