Why the Oz vs Liter Confusion?
Canada officially uses litres. The US uses fluid ounces. Most Canadian water bottles are labelled in millilitres or litres. Most US-made hydration apps track in ounces. If you use both, you'll hit this conversion constantly.
The simplest fix: pick litres and stick to them. Your daily target of 2.5–3L maps cleanly to one or two large-bottle fills — no mental math required.
