So, consider the following. You're told to mix 1 tablespoon of solvent to 1 cup solute but you also need to reduce it down so you're only dealing with 3fl oz of solute. How much solvent do you need?

Now, look at the metric equivalent: 15ml of solvent to 250ml solute

And you need to reduce it to 100ml

This gives you a rather easy equation and leaves you mixing 6ml of solvent.

So, if your doctor gave you the equation above, what would you prefer it in, US customary or metric?

Yes, for those wondering, the doctor actually meant 250ml but had converted that to 1 cup (oops, rounding error!) for the "average patient".
