1. Conversion factors help!

Hello!

I was just studying for chemistry and encountered 'Conversion factors' and have a few questions for that. Hope i'm in the correct thread.

Anyway. In the textbook it gives the example of converting from 576 cm -> yards. They go from cm -> in -> ft. -> yd. Is there any reason they went from cm -> in and not directly from cm -> yards?
Are there any other resources i can use to better my understanding of conversion factors. I am just lost as to why you go from unit -> unit -> ... instead of jumping from one unit directly to another.

I am sorry if this is a dumb question .

Thanks!

It's not a dumb question. I think it's just a matter of commonly used conversions.

Off the top of my head I know that there are 2.54cm to an inch. I couldn't tell you offhand what 36 times that is.

Similarly pretty much everyone knows there are 12 inches to a foot and 3 feet to a yard. (I'd like to think that anyway)

Fewer folks would immediately know there are 36 inches to a yard.

If you have a conversion factor from cm directly to yards at your fingertips go ahead and use it but it's usually easiest to just remember the base conversions and daisy chain them like this.

So it's just a matter of remembering the basics.
Perfect, thank you!
