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 gallon (gal) is a unit of volume, most commonly associated with the imperial and US customary systems of measurement.
It is equal to 128 Fluid Ounces (fl-oz).
A common point of confusion is the difference between the US gallon and the imperial gallon (used in the UK and other Commonwealth nations).
They are not the same size!
This difference stems from historical definitions that were standardized differently in the US and Britain during the 18th and 19th centuries.
So, if you're comparing fuel efficiency, remember that "miles per gallon" ratings are based on different-sized gallons!
The word "gallon" has a rich history, tracing its roots back through several languages.
It originates from the Old Northern French word galon, which referred to a liquid measure.
This term is believed to have originated from the Gallo-Roman word gallēta, meaning a "pail" or "bucket." The ultimate origin likely goes back to a Celtic word, highlighting the unit's long-standing use in European trade and daily life for centuries.
While we typically associate the gallon with liquids, there is also a US dry gallon.
This unit, not commonly used today, is equivalent to one-eighth of a bushel, or about 4.405 liters. It was historically used to measure dry goods such as grain or fruit.
This is also why the famous "10-gallon hat" is a misnomer; its name doesn't refer to its volume.
Instead, it is thought to originate from the Spanish word galón, meaning "braid," which refers to the braided band on the hat.
