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.

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.
Frequently Asked Questions
- What is the size of a medium grapefruit?
- A medium grapefruit weighs about 246 g, which works out to roughly 1.02 cups (1.07 US cups) of chopped flesh. Grapefruits come in a range of sizes depending on the season, variety and where they were grown, so weight and cup figures shift accordingly. Use the size selector above to match what you actually have, then read the exact conversion for any amount.
- How much does an average grapefruit weigh?
- An average grapefruit is the same as a medium one: about 246 g. A small grapefruit is lighter at around 200 g and a large one heavier at about 332 g, so the size you actually have changes the total for any recipe that counts grapefruits by the piece rather than by weight.
- How much does a large grapefruit weigh?
- A large grapefruit weighs about 332 g, noticeably more than a medium, or average, one at 246 g or a small one at 200 g. Set the size selector to large to convert cups, grams and ounces for the bigger grapefruits you actually have on the counter.
- How much juice is in a grapefruit?
- A grapefruit yields approximately 65% of its weight in juice. That means a medium grapefruit (246 g) yields about 160 ml, a small one (200 g) about 130 ml and a large one (332 g) about 216 ml. See the juice yield calculator if you are adding grapefruit to your juice blend. Open the juice yield calculator
- How do I convert grams to ounces for any ingredient?
- Converting grams to ounces is pure weight maths that applies to any food, not just grapefruits, so 200 grams is always 7.05 ounces. For other amounts, the weight converter at the link below handles grams, ounces, pounds, kilograms and stone in both directions. Grams to ounces converter
Related to Grapefruit
Orange
Orange (190 g/cup) is lighter than grapefruit (240 g/cup) and significantly sweeter with none of the bitter edge. Works in salads, marmalade, and dressings. Add a small squeeze of lemon or reduce sugar slightly to keep the tartness if the bitterness was load-bearing in the recipe. See our Orange converter.
Lemon
Lemon is sharper and more purely acidic than grapefruit, without the bitter, floral notes. A cup of lemon juice weighs 255 g and swaps in cup for cup. Use lemon when you want clean citrus acid in dressings, marinades, and cocktails; add a pinch of sugar if the recipe relied on grapefruit's hint of sweetness. See our Lemon converter.
