Memorizing Units
Anyone know if we have to fully memorize any specific unit conversions?
The first question on Achieve was a conversion from mi/gal to km/L, would we have to know in our heads what 1 mile is in km or 1 gal to L or would this be provided/can we look it up in the future?

Re: Memorizing Units
I was wondering the same thing but I imagine we'll eventually memorize important conversions

Re: Memorizing Units
It's probably best to memorize some of the basics/ones we use often since it might not be given to us on tests.
Re: Memorizing Units
I think we should know the basic metric conversions (kilo, milli, centi, etc) by memory but the others we will probably learn along the way.

Re: Memorizing Units
I don't think we'll need to know conversions like km to miles. But, it's probably best to keep in mind the simple and basic ones like hours to seconds or grams to milligrams.
Re: Memorizing Units
I think the Achieve problem was just trying to teach how to set up the stoichiometric conversions between miles and km, and gallons and L (like how km in the numerator*km in the denominator would cancel out km). I believe the values needed to convert between those units will be given, however.

Re: Memorizing Units
Based on the fundamentals of chemistry practice problems that were assigned, it seems that the most important conversions to know by heart are milli- to base unit, kilo- to base unit, and vice versa. Those two were the most common conversions necessary to solve a significant number of problems. There were one or two questions with conversions such as tons- to base unit, but I suspect that we would not see this often.

Re: Memorizing Units
I believe that we are expected to know the most common conversions (such as mins to hours) and the values indicated by numeral prefixes (centi, milli, etc), but other, more uncommon, conversion factors will probably be given.

Re: Memorizing Units
I think that it is good to know the basic conversions like kilo, hecto, deca, deci, centi, milli. A fun acronym for this that I've learned is "King Henry Died Usually Drinking Chocolate Milk".

Re: Memorizing Units
As others said, it's always good to know some of the basic unit conversions such as the nano to kilo, mi to km, L to mL, and etc. However, I think we might be given most of these conversions or at least the ones that aren't as intuitive for one to know. Something that helps me is to write all the conversions down on a piece of paper instead of printing it out because that way I also review it as well as have kind of like a "tool" to use when I am doing my homework.

Re: Memorizing Units
Hi guys, do you know what the measurement is for a pico, I didn’t catch it during lecture?

Re: Memorizing Units
Hi!! I can't figure out how to respond to the specific comment but someone in the thread was asking about the measurement signified by a pico, which is 10^-12! So for example 1 picometer would be equal to one meter times 10^-12! Also, in terms of memorization, I agree with what's been said; I think we most likely will have to memorize prefixes to use the correct scale when doing calculations, as well as everyday conversions involving time (e.g. seconds to minutes to hours) and temperature (e.g. celsius+273.15=kelvins), but non-obvious/commonly known measurement conversions will probably be provided when needed. :)
