US Cups to Cubic Miles (cup to mi³)
1 US cup equals 5.676053647×10⁻¹⁴ cubic miles (rounded).
How to convert US cups to cubic miles
To convert US cups to cubic miles, multiply the number of US cups by 5.676053647×10⁻¹⁴. The factor is rounded to 10 significant digits. To go the other way, multiply cubic miles by 17,617,874,358,857 (rounded).
cubic miles = US cups × 5.676053647×10⁻¹⁴
Example: 10 US cups = 5.676053647×10⁻¹³ cubic miles.
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
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).

Cubic Mile (mi³)
About 4.168 cubic kilometers. Used for very large volumes.
Defined as the volume of a cube whose sides are one mile, this unit belongs to the imperial and US customary systems and is used in the United States, Canada and the United Kingdom. Because the international mile is exactly 1,609.344 meters, the cubic mile is fixed too: about 4.168182 cubic kilometers, a value NIST lists as 4.168 182 times 10 to the 9 cubic meters.
Other equivalents give a feel for its size. Wikipedia lists about 3.38 million acre-feet, around 1.1 trillion US liquid gallons and roughly 147 billion cubic feet. The figure used here is 4,168,181,825,440.58 liters, matching the Wikipedia value of 4.168181825 km3. Since a cubic kilometer is about 0.2399 of a cubic mile, converting between the two is a matter of a factor a little over four.
1 cubic mile = 4,168,181,825,441 liters (approximately).
