Gotcha. Now I understand, round to the number of places that your least accurate measurement consists of (can't remember the name for doing that, lol). Damn it's been a long time since I've been in math. After Calc in High School I haven't been back to class!
For adding chemicals to water I would think percentages, decimals and converting units of measure would be the most important.
