What is a fluid ounce?
A US fluid ounce is a small liquid volume, one eighth of a cup.
Definition: Exactly one 128th of a US liquid gallon, so exactly 29.5735295625 milliliters.
Where it is used: Beverage cans and bottles, cosmetics, and small liquid quantities in the US.
Worth knowing: Measures volume, not weight — a fluid ounce of water weighs about 1.04 avoirdupois ounces. The imperial fluid ounce is 28.41 mL.
What is a cubic meter?
A cubic meter is the SI unit of volume — the space in a one-meter cube.
Definition: Derived directly from the meter. Exactly 1,000 liters.
Where it is used: Freight and shipping volume, concrete and timber quantities, natural gas metering, and HVAC airflow.
Fluid Ounces vs Cubic Meters
The fluid ounce is a US customary unit while the cubic meter is an SI unit. That is why the factor between them is not a round number: the two systems were defined independently and only later tied together by exact agreement.
