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 grapefruit 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.

Grapefruit 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 grapefruit varieties compare.

Variety	Best for
Ruby Red	Juice and breakfast halves: sweet, low-acid, deep pink flesh.
Pink (Marsh)	Fresh eating and salads: mild, juicy, and seedless.
White (Marsh)	Marmalade and sharper dishes: the classic tart-bitter flavour with pale flesh.
Oroblanco	Salads and segments: sweet, nearly seedless pomelo cross with low bitterness.

Which should I pick?

For juice and breakfast halves, Ruby Red is the sweet, low-acid default with deep pink flesh. No Ruby Red? Pink (Marsh) is a touch milder and nearly as juicy. Reach for White (Marsh) when you want a sharper, more bitter classic note, or Oroblanco for a sweet, nearly seedless segment in salads.
