What is the size of a medium cucumber?

A medium cucumber weighs about 300 g, which works out to roughly 2.16 cups (2.26 US cups) of chopped flesh. Cucumbers 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 cucumber weigh?

An average cucumber is the same as a medium one: about 300 g. A small cucumber is lighter at around 150 g and a large one heavier at about 400 g, so the size you actually have changes the total for any recipe that counts cucumbers by the piece rather than by weight.

How much does a large cucumber weigh?

A large cucumber weighs about 400 g, noticeably more than a medium, or average, one at 300 g or a small one at 150 g. Set the size selector to large to convert cups, grams and ounces for the bigger cucumbers you actually have on the counter.

How much juice is in a cucumber?

A cucumber yields approximately 90% of its weight in juice. That means a medium cucumber (300 g) yields about 270 ml, a small one (150 g) about 135 ml and a large one (400 g) about 360 ml. See the juice yield calculator if you are adding cucumber to your juice blend.

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 cucumbers, 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.

Cucumber converter: whole cucumbers, cups, grams

A recipe says '1 cup chopped cucumber' but you have a couple of whole ones on the counter. A medium cucumber weighs about 300 g, so the count shifts as size changes. This converter moves between whole cucumbers, chopped cups, grams, and ounces.

Cucumber 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 cucumber varieties compare.

Variety	Best for
Slicing (American Slicer)	All-purpose salads and snacking: dark-green waxed skin (usually peeled), watery flesh; the cheap supermarket default.
English (Hothouse)	Salads and sandwiches: long, seedless, thin-skinned; no peeling needed and the mildest flavour.
Persian / Lebanese	Snacking and salads: small, crisp, seedless; eat skin and all.
Kirby (Pickling)	Pickles and quick brines: short and bumpy, firm flesh that stays crunchy in vinegar.
Armenian (Yard-long)	Salads and tzatziki: long and ribbed, technically a melon; thin skin, mild and crisp.

Which should I pick?

For salads and sandwiches, English / Hothouse is the pick: long, seedless, thin-skinned, no peeling needed. No English? Persian / Lebanese cucumbers are smaller but equally crisp and mild. For pickling, Kirby is the standard, with bumpy skin and firm flesh that stays crunchy in brine. Reach for the everyday American Slicer when you want a cheap bulk option for big salad bowls.
