How do I convert US cups to cups for any recipe?

Switching between metric cups and US cups is a fixed volume ratio that applies to any ingredient, since one US cup is 240 ml and one metric cup is 250 ml. The volume converter at the link below covers cups, US cups, millilitres, tablespoons and teaspoons in both directions.

What is the difference between a metric cup and a US cup?

A metric cup holds 250 ml while a US cup holds 240 ml, so a US cup is 4% smaller. For chopped lemon that gap is small but real, and it adds up across several cups. The guide linked below explains when the difference matters and how to switch between the two so a recipe lands right whichever cup you own.

Lemon varieties and best uses

The conversions above are the same whatever variety you use; the difference is what each is good for. Here is how the common lemon varieties compare.

Variety	Best for
Eureka	Everyday lemon juice: reliable, widely stocked, very juicy.
Lisbon	Baking, canning, and lemonade: flavour close to Eureka, good acid.
Meyer	Desserts and dressings: sweeter and less sharp, thin-skinned.
Amalfi	Zesting and gourmet baking: intensely fragrant peel, low bitterness.

Which should I pick?

For dressings, curds, and cocktails, Eureka is the go-to: widely available and reliably juicy. No Eureka? Lisbon is nearly identical and works in any recipe that calls for lemon. Reach for Meyer in desserts where a sweeter, less sharp citrus note suits the dish.
