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.
A liter (l) is a fundamental unit used to measure volume in the metric system.
In simple terms, it measures the amount of space a substance occupies, like the amount of soda in a bottle. The plural form is liters.
The liter was introduced in France in 1795 during the French Revolution.
It was created as part of a movement toward a more logical and universal system of measurement, which later evolved into the modern metric system.
Initially, the definition of a liter was based on the weight of one kilogram of pure water.
While the original definition was based on the mass of water, it was updated for greater precision and consistency.
Today, the official definition directly connects the liter to a unit of length, making it easier to understand.
So, how big is a liter?
A liter is officially defined as exactly one cubic decimeter (1 dm3).
This means a liter is the volume of a perfect cube with sides that are each 10 centimeters long (10 cm × 10 cm × 10 cm).
The difference between "liter" and "litre" is simply a regional spelling choice—the volume they represent is precisely the same!
Both spellings are correct, and the one you use depends on where you are.
