Grapefruit converter: whole grapefruits, cups, grams

A recipe says '1 cup grapefruit segments' or '2 grapefruits' but they range from small to large. A medium grapefruit is about 246 g whole, so the count shifts as size changes. This converter moves between whole grapefruits, segmented cups, grams, and ounces.

A small grapefruit is 200 g and a large one 332 g, so 'two grapefruits' can swing from 400 g to over 650 g of fruit. Pick the right size below to keep salads, marmalade, and breakfast bowls on target.

Pink (Marsh)Fresh eating and salads: mild, juicy, and seedless.
White (Marsh)Marmalade and sharper dishes: the classic tart-bitter flavour with pale flesh.
OroblancoSalads 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.
