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 sweet potato 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.
