Grapes converter: whole grapes, cups, grams
A recipe says '1 cup grapes' or '2 cups halved grapes' but you bought them by the bunch. A medium grape is about 5 g, so the count climbs fast as grape size changes. This converter moves between whole grapes, cups, grams, and ounces.
A large grape weighs more than twice a small one, so a cup of grapes can be around thirty small grapes or far fewer large ones. Pick the right size below to keep fruit salads, roasting trays, and snack boxes on target.

Grapes 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 grapes varieties compare.
| Variety | Best for |
|---|---|
| Red Seedless | Snacking and salads: sweet, crisp, and easy to eat whole. |
| Thompson (Green) Seedless | Fresh eating and roasting: mild and sweet, the green supermarket standard. |
| Black | Fresh eating and roasting: deeper, richer flavour with dark skin. |
| Concord | Juice, jelly, and jam: bold and jammy with seeds and a slip skin. |
Which should I pick?
For snacking and fruit salads, Red Seedless and Thompson (Green) Seedless are the sweet, reliable supermarket defaults. No seedless? Black grapes are richer and work as well fresh or roasted. Reach for Concord when you want a bold, jammy grape for juice and jelly, though it carries seeds and a slip skin.
Frequently Asked Questions
- What is the size of a medium grape?
- A medium grape weighs about 5 g, which works out to roughly 0.03 cups (0.03 US cups) of chopped flesh. Grapes 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 grape weigh?
- An average grape is the same as a medium one: about 5 g. A small grape is lighter at around 3 g and a large one heavier at about 8 g, so the size you actually have changes the total for any recipe that counts grapes by the piece rather than by weight.
- How much does a large grape weigh?
- A large grape weighs about 8 g, noticeably more than a medium, or average, one at 5 g or a small one at 3 g. Set the size selector to large to convert cups, grams and ounces for the bigger grapes you actually have on the counter.

- How much juice is in a grape?
- A grape yields approximately 65% of its weight in juice. That means a medium grape (5 g) yields about 3 ml, a small one (3 g) about 2 ml and a large one (8 g) about 5 ml. See the juice yield calculator if you are adding grapes 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 grapes, 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
