A cubic inch (in3) is a unit of volume in the imperial and US customary systems of measurement.
One cubic inch is equal to about 0.554 fluid ounces (fl oz).
One cubic inch is precisely equal to 16.387064 cubic centimeters (cm3).
This exact conversion is legally defined and crucial in fields like engineering, science, and international manufacturing, where precision is paramount.
It enables the direct and accurate translation of volume measurements between the imperial system (common in the US) and the metric system, which is used worldwide.
The cubic inch is famously used to measure an engine's displacement (often abbreviated as CID), especially in American automotive history.
Engine displacement refers to the total volume of air and fuel that an engine's cylinders can move through in one cycle.
A higher CID, such as in the classic "454" (454 in3) V8 engines, typically meant more potential for power and torque, defining the era of American muscle cars.
To visualize a cubic inch, think of a small, common object.
A standard six-sided die used in board games is a perfect example, having a volume very close to one cubic inch.
A small sugar cube or a standard marble also provides a good real-world approximation of this unit of volume, making it easier to conceptualize its size beyond abstract numbers.
A cup is a unit of volume measurement equal to 8 fluid ounces (fl oz).
It's one of the most common measurements used in recipes for cooking and baking, especially in the United States.
While they share the same name, not all cups are created equal.
A US customary cup is defined as 8 US fluid ounces (approximately 237 milliliters).
However, the metric cup used in countries like Australia, Canada, and New Zealand is standardized to 250 milliliters.
This slight difference is crucial to remember when following international recipes to ensure the correct ingredient proportions.

The name of the measurement isn't a coincidence. Before standardized units became common, recipes relied on informal measurements using everyday kitchenware.
The "cup" literally referred to the volume of a standard teacup. Over time, this was standardized into the precise unit we use today.
Although the unit of volume (8 fl oz) remains the same, the tools used to measure dry and liquid ingredients differ for a reason.
Using the wrong type can lead to inaccurate measurements.
