It depends... "una (vez) cada día" = "one (time)/once each day" "una (vez) por día" = "one (time)/once per day" "una (vez) al día" "one (time) a day" |

Well, the units can be all kinds of different things ... m/s, miles/h, km/h, miles/sec, etc.
You said "it depends", but I'm wondering, what does it depend on? In Spanish math classes, do they teach two different scenarios? Sometimes you say "cada" and sometimes you say "por"? |

55mpg $2.17 a gallon/per gallon Doesn't it depends in English too? ;) |
I wouldn't ever use "each" in units as a label in English. So I suppose I would never use "cada" in units as a label in Spanish, right?

Well, this is something that I've pondered for about a week before posting the question, so I'll continue to pursue it. If you want to stop answering, I'm sure someone else will pick it up...
The example you give (For each gallon of water, pour 1 cup of bleach.), that is typical of a science class. I'm specifically looking for math problems given strictly in the context of a math classroom. And you're describing a process, not giving a quantity with units. In my class, I would ask something like follows: - If light travels xxxxx miles in 8 minutes, what is the speed of light given in miles/second? I would tell English speaking students that "per" means that the denominator is "one", and that they have to convert from 8 minutes to 60 seconds in a minute and make the denominator 1. I can't think of an instance where I would use "each"........ |

I didn't realize you had been pondering this for some time... No need to become belligerent. :) Quote:
The rest somebody else will have to answer it, as I am not understanding your position. Maybe when I get back to this post I will have an insight or something... :) |
It wasn't my intention to seem belligerent. Take what I said at face value. I ponder things like this before I ask.... :)
Sounds like "por" is a better choice for what I'm looking for....... |
