🥤About 7 million 12-fl-oz drinks.

Wait — fluid ounce?

An ordinary ounce (oz) is a unit of mass. A fluid ounce (fl oz) is a unit of volume. So a 12-fl-oz drink doesn’t necessarily weigh 12 ounces — that depends on what’s inside.

The pool side is a 50 × 25 × 2 m rectangle. Make it deeper and you’d need far more drinks to fill it — but more water underneath you doesn’t move the finish wall.

A U.S. fluid ounce and an Imperial fluid ounce are different units. So even “12 fl oz” still needs a measurement system when precision matters — the same trap as the U.S. and Imperial gallons.

U.S. fluid ounce

1 US fl oz ≈ 29.5735 mLReference value

One 12-US-fl-oz serving

12 × 29.5735 mL ≈ 354.9 mL ≈ 0.3549 LCalculated

Pool reference

50 × 25 × 2 m = 2,500,000 LReference value

Scaleidoscope’s defined reference, not a universal pool volume

Derived comparison · reference-defined. NIST defines the U.S. fluid ounce and the pool is Scaleidoscope’s stated reference. The division is ours, rounded to 7 million.

Liquid-volume equivalence against the same pool reference.
