The chef's caveat

Fluid oz vs. grams

US labels use fluid oz (a volume) while nutrition math wants grams (a weight). For thin drinks 1 ml ≈ 1 g, so the two match closely. Thick drinks (smoothies, protein shakes) are the exception — 100 ml can weigh 115–130 g.

Is the diet version really zero calories?

Effectively yes — most zero-sugar sodas measure at 1–3 calories per can, which the FDA lets round to zero. Whether the sweeteners are neutral for your body is a separate debate; the calorie count is not.
