Imperial oz vs US oz — Is There a Difference?
Yes — slightly. The US fluid ounce = 29.574 mL. The Imperial fluid ounce (UK/Canada official) = 28.413 mL. The difference is small (about 4%) but relevant for precise measurements.
In practice, almost all Canadian water bottles, hydration apps, and nutrition labels use US fluid ounces when oz appear at all — metric (mL/L) is standard in Canada.
