Sorry you've not had any responses about this. Are you sure you’ve posted in the right place? Posting in the specific Study Help forum should help get responses.

I'm going to quote in Tank Girl now so she can move your thread to the right place if it's needed. :yy:

Once you use them enough you learn them all. Most of the time you only need to go from +9 to -9 so memorise those ones first. However, I would say that learning the rest is useful.

You generally have to try and get a feel for them like micro think when you were using micrometers that they aren't that small and are obviously smaller than millimetres as you can measure them with a ruler they must be 10^-6.Its the same with all of them really giga and mega sound really big mega sounds like a million giga sounds bigger, nanometres are using commonly in science experiments and sci-fi whereas you don't hear of scientists using picometres or femtometres as much and you should remember their usage when learning about particles so you will know they are very very small.Some of the common prefixes you should know already like kilo,deci,milli they are the most commonly used.

I found the large ones fairly easy to remember because they're the exact same ones used in computer memory - then again I guess it depends if you pay attention to the size of your files.
