Mixing Drinks Matters—Here’s Why 16 oz Equals Exactly 473 mL (The Truth Everyone Ignores) When you’re crafting the perfect cocktail, the size of your glass matters—tag identically, 16 ounces isn’t just a round number. It’s a precise measurement rooted in international metric standards that ensures consistency, fairness, and skill behind every drink. Believe it or not, 473 mL isn’t a lucky figure or an approximation—it’s an exact science that every bartender and drinker should understand. ### The Exact Mark: How Many Milliliters Are in 16 oz? In the U.S. system, 1 ounce (fl oz) equals exactly 29.5735 milliliters. But what most people don’t realize is that when standardized, 16 fluid ounces (16 fl oz) precisely equals 473 milliliters. This conversion comes straight from the International System of Units (SI), where 1 fl oz is defined as 29.5735 mL—but in practical cocktail mixing, a practical approximation of 473 mL is widely accepted as the standard for a 16 oz glass.
