Can anyone check my math for dilution ratios?

Dilution ratios are usually water:chemical, so it would read 10:1.

A ratio reads, for every 10 ounces of water, there is 1 ounce of chemical.

So, if you had 11 ounces of product, that is mixed 10:1, you would have 10 ounces of water and 1 ounce of chemical.

To shake things up a bit, lets say you have 10 ounces of product, that has been mixed 10:1, you would have ~9.09 ounces of water, and a ~0.91 ounces of product.

3:27 is 1:9 BTW.

This is why I am frequently on the losing end of these arguments.

I was thinking more along the lines of 3oz product into 27oz water = 3oz/30oz total instead of 3:27 or 1:9.

thanks for all the feedback! the other pc, I like the idea of mixing everything in a big container and then pour into the spray bottle, I will probably use this method until I get some megs spray bottles, since those call for th water 1st then the product. thanks again
