Cubic Meters to US Cups (m³ to cup)
1 cubic meter equals 4,226.752838 US cups (rounded).
How to convert cubic meters to US cups
To convert cubic meters to US cups, multiply the number of cubic meters by 4,226.752838. The factor is rounded to 10 significant digits. To go the other way, multiply US cups by 0.0002365882365.
US cups = cubic meters × 4,226.752838
Example: 10 cubic meters = 42,267.52838 US cups.
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 Cup (cup)
One sixteenth of a US gallon, 236.588 mL (8 US fluid ounces). The standard US recipe cup.
Cups began as household drinking vessels, not scientific units, which is why they remain the messiest measures in the kitchen. The US customary cup was defined by slicing up the gallon: half a pint, or eight US fluid ounces, about 236.6 milliliters. Unlike the larger units, nobody ever fixed it to a physical vessel, so it exists only as a fraction of the gallon.
The customary cup is not the only American cup. For nutrition labels, US regulation defines a cup as exactly 240 milliliters, a rounder figure that sits slightly above the customary size. Packaged foods therefore list a serving in the legal cup while a measuring cup from the hardware store follows the customary definition. The gap is 3.4 milliliters, which hardly matters for soup but can matter in baking. Cup measures also hide the weight of dry ingredients, since a cup of sifted flour and a cup of packed flour differ substantially, which is why much of the world prefers grams.
1 US cup = 0.2365882365 liters (exactly).
