The Definition of Cup
To find out how many cups are in a liter, first, we must define what a cup is. A cup is simply a measurement unit that denotes volume, typically employed to measure liquids or dry ingredients. It is frequently employed in both the US system (Customary system) and the UK system (Metric system).
However, The US and UK systems also have different definitions for a cup – in the US system, 1 cup equals 8 fl oz or 236,588327 ml whereas, in the UK system, 1 cup equals 10 fl oz or 284 ml.
In the US system: 1 Cup = 236,588 ml
In the UK system: 1 Cup = 284 ml
The Definition of Liter
Now that we know what a cup is, let’s move on to defining what a liter (l) is. A liter (or litre for those in the UK) is also a measurement unit, but it denotes capacity instead of volume. Specifically, it measures the capacity or volume of liquid substances such as water, milk, oil, and other beverages.
A liter equals 1000 milliliters (ml) in the Metric system, or 1.057 quarts in the US Customary system – making it a larger unit for measurement than a cup.
1l = 1000 ml
