Cubic Meters to US Fluid Ounces (m³ to fl oz)
1 cubic meter equals 33,814.0227 US fluid ounces (rounded).
How to convert cubic meters to US fluid ounces
To convert cubic meters to US fluid ounces, multiply the number of cubic meters by 33,814.0227. The factor is rounded to 10 significant digits. To go the other way, multiply US fluid ounces by 0.00002957352956 (rounded).
US fluid ounces = cubic meters × 33,814.0227
Example: 10 cubic meters = 338,140.227 US fluid ounces.
Pints, quarts, gallons and fluid ounces differ between the US and the UK. Units are labeled 'US' or 'imperial' to avoid confusion.
About these units
Cubic Meter (m³)
The SI derived unit of volume: 1,000 liters. Used for water supply, gas, concrete and shipping space.
When the metric system was set up, the cube whose edge is one meter became its natural large unit of volume. A cubic meter also went by other names: kiloliter, now rarely used, and stere, still applied to stacked firewood. In modern SI it is the coherent derived unit of volume, and the liter is a convenience unit defined from it as one thousandth of a cubic meter.
A cubic meter is large by everyday standards. It holds 1,000 liters, and pure water at its densest weighs almost exactly one tonne in that space, which is how the metric tonne and the cubic meter ended up so conveniently paired. It is the unit of choice for water supply, gas, timber, concrete and shipping space, where freight is often quoted in CBM. For a picture, about 6.29 oil barrels or 264 US gallons fit in one, and an Olympic swimming pool, at least 2 meters deep, holds roughly 2,500 of them.
1 cubic meter = 1,000 liters (exactly).

US Fluid Ounce (fl oz)
One 128th of a US gallon, 29.5735 mL. Not the same as the weight ounce, and about 4% larger than the imperial fluid ounce.
Fluid ounce began as an attempt to link volume to weight: the volume occupied by one ounce of some substance, such as wine in England or water in Scotland. Definitions varied by region and by liquid. When Britain defined its imperial gallon in 1824 as the space of ten pounds of water, the imperial fluid ounce came out so that an ounce of water weighs about one avoirdupois ounce. The US fluid ounce followed a different path and comes from the older wine gallon.
The US fluid ounce is exactly 1/128 of a US gallon, 29.5735295625 milliliters, about 4 percent bigger than the imperial one at 28.4130625 milliliters. American nutrition labels use yet another figure, treating one fluid ounce as 30 milliliters, a convenient rounding for serving sizes. The name is a trap, because a fluid ounce measures space while a weight ounce measures mass. A US fluid ounce of water weighs a bit more than an ounce of weight, while a fluid ounce of honey weighs considerably more.
1 US fluid ounce = 0.02957352956 liters (approximately).
