So I was looking at my fertilizer seeing what it’s lacking (a couple micronutrients: calcium and boron specifically) so I went looking for a calculator to convert ppm into grams per gallon and found this. Convert Parts Per Million to Ounces Per Gallon (ppm to oz/gal) ― JustinTOOLs.com

Looks clever but does it specify which kind of gallon? There are a few.

It’s easy to work out the UK gallon unlike you Mericans. 
1000ml to a litre.
5 litres or 5000ml to a UK gallon.
A pint here is 568ml (I’m sure in Canada it’s a legal requirement that a pint of beer has to be 568ml also??)

Gotta go buy a pound of borax to use less than a gram of it over a grow. Good thing that shits cheap.
