Sure, of course you can convert between those, but as the article explains, it's not a good practice to start out with ratios. You need a certain amount of grams of, say, fats, not a certain share of the total intake. If you need 70g of fats to function normally and you're eating 50g, then it doesn't matter whether those 50g represent 20% or 50% of your total intake. It's not enough and that's what matters. The only reason why ratios "work" for some people is that they unwittingly select a ratio that just so happens to work for them in that case. The practice of doing so is still wrong and can lead to deficiencies.
