How do I convert cups to US 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 butternut squash 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.

Variety	Best for
Butternut (standard)	Everyday roasting, soup, and curry: sweet orange flesh that purées smoothly, the all-purpose supermarket squash.
Waltham	Pies and roasts where flavour matters: heirloom benchmark with deep, sweet, nutty flesh.
Honeynut	Single servings and roasting whole: palm-sized mini version with very sweet, concentrated flesh.
Crown Prince	Roasting and gnocchi: blue-grey skin and denser, drier flesh that holds its shape and substitutes well for butternut.

Which should I pick?
