A cup is a non-standardized measure somewhere between 65 ml (16 to the liter) to 285 ml (3.5 to the liter). But since you even mention them as a measure, and you write it “liter”, you’re probably from the USA, which has only 5 different cups. The most likely ones are 236.4 ml, 238 ml or 240 ml. Taking the last (because it’s a rounder number), you have a little over 4 “cups” to a liter (more precisely, 4.1667). There are approximately 33.814 US fl ounces per liter  
Similarly, there are 8 fl ounces per cup  
Consequently (33.814/8) 4 cups and  
1.814 left over ounces in a liter.  
Equal to what?  
1 liter is 1dm^3 is 1000 cm^3  
1 inch is 2,54 cm  
1 liter is 33.9 US fluid ounces  
1 liter is 35.2 Imperial fluid ounces  
1 liter is 60.7 cubic inches  
1 US gallon is 3.8 liters  
1 Imperial gallon is 4.5 liters  
2 imperial pints are about 1.1 liter  
The numbers are not exact. takes a lot of decimals to fit.  
Would be nice when the US and the UK convert to the International System of Units. Several accidents with airplanes could have been avoided and it could have saved a Marslander and some $$$. Originally, the kilogram was supposed to be the weight of a cubic decimeter of water. They weighed the water, then made the official metal kilogram weight. So naturally it turned out, on further investigation, that the metal kilogram didn’t weigh exactly the same as the cubic decimeter of water. So a liter of water was then defined as the amount of water that actually did weigh a kilogram. A liter is a metric unit of capacity, formerly defined as the volume of 1 kilogram of water under standard conditions, now equal to 1,000 cubic centimeters (about 1.75 pints). There are two very common “cups”. The Imperial and the US. Several people have posted the answer viz the difference for cooks. An Imperial cup (UK measurement) would come out as just over 3.5 to the liter. One US (standard) cup comes out to just under 4.25 to the liter. This doesn’t destroy many recipes but in certain confections and pastries if you have one wild card in the recipe, e.g. chocolate by weight or butter by weight, you can wind up with a mess. And don’t get me started on US “legal” cups. No one uses them. It’s a variation on the U.S. Cup used by nutritionists for easier calculation of all that stuff on the label of you bag of Cheetos. There’s also such a thing as a Metric Cup for the mathematically challenged. (Duh 1 divided by 4 is how many?. Proper recipes should be in fluid ounces or milliliters. Each is defined and has a known ratio to the other. Proper pastry and confectionery chefs actually use WEIGHT for dry ingredients and volume for liquid. (And have fun tackling the eggs! We all still use X large or Y medium eggs. You wanna make a proper flan or custard or creme patissiere? You should know the weight. We get a similar question to this all the time in the Coffee Geeks groups. How many cups does XXX coffeemaker hold? The answer is that they actually shouldn’t be allowed to say “capacity = 8 cups” because they mean 8 arbitrary “servings” of your grandma’s china cup, which is about 5.5 fluid ounces. Most people have a measuring cup that has a standardized measure on it . That measure is 8 oz… and on the other side of the measuring device it has a metric conversion rounded off to avoid imperial royal confusion . Its rounded to 250ml. 1 liter is 1000ml so 1000÷250 =4 Have a look at this . Closest side is metric 250ml far side is imperial 8 oz and you can see the 1 just showing for 1 cup. You cannot ask: How many cups of water (of unspecified volume!) equal to a liter? You have different sizes of cups - hence any answer could be correct! If I take the volume of a cup as 100 ml, 120 ml, 80 ml, 90 ml or 160 ml - each would give me different number of cups to make a liter. This question can be like: How many buckets make one cubic meter? What size of a bucket? You have small buckets that kids make sand castles on the beach - and buckets that - if filled with water - you cannot even lift! Let us be more precise and ask questions that can be answered definitively. This depends on your cups…. A “standard” U.S. Customary Cup = 8 fl oz or 1/2 pint, approximately . There’s also a bunch of other different types of cups, like Metric, Imperial, and U.S. “Legal” cups. … Let me list a few… approximately 237 mL.  
1 Liter = 4.22675 U.S. Customary Cups  
1 Liter = 4 1/6 U.S “Legal” Cups  
1 Liter = 3.51951 Imperial Cups  
1 Liter = 4 Metric Cups  
1 Liter = 5 Japanese Cups
