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.
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.
Cubic Meters vs Fluid Ounces
The cubic meter is an SI unit while the fluid ounce is a US customary 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.
