Blueberries: US, metric & UK cups compared
A “cup” isn’t the same size everywhere, so 1 cup of blueberries weighs a different number of grams depending on which cup your recipe uses. The US cup is 236.6 ml, while Australia, New Zealand, Canada and modern UK recipes use a 250 ml metric cup. Here’s 1 cup of blueberries in each:
| Cup standard | Size | 1 cup blueberries | Used in |
|---|---|---|---|
| US cup | 237 ml | 148 g | United States (most US recipe sites) |
| Metric cup | 250 ml | 156 g | Australia, NZ, Canada & modern UK |
| UK imperial cup | 284 ml | 178 g | Older British recipes |
| Japanese cup | 200 ml | 125 g | Japan |
Unless a recipe says otherwise, US recipes mean the US cup and Australian/UK recipes mean the 250 ml metric cup. The tables higher up this page use the US cup.

Blueberries by the spoonful and by the ounce
Recipes rarely stop at cups. One tablespoon of blueberries weighs about 9.25g, and one teaspoon about 3.08g, because a US cup holds 16 tablespoons or 48 teaspoons.
- 1 tablespoon blueberries to grams = 9.25g
- 2 tablespoons blueberries = 18.5g
- 3 tablespoons blueberries = 27.8g
- 1 teaspoon blueberries = 3.08g
Weight units do not depend on the ingredient, so 8 oz of blueberries is 227g and 4 oz is 113g, the same as 8 oz of anything else. That 8 oz is 1.53 cups of blueberries — the number that does change, because it depends on how much a cup of blueberries weighs.
How many cups is 100g, 200g or 300g of blueberries?
Because one cup of blueberries weighs about 148 grams, you can convert any weight to cups by dividing by 148. So 100g of blueberries is about 0.68 cups, 200g is about 1.35 cups, 250g is about 1.69 cups, and 300g is about 2.03 cups. For any other amount, type the grams straight into the converter above and switch it to show cups.
How to measure blueberries accurately
For the most reliable baking results, weigh blueberries on a kitchen scale rather than scooping by volume. One US cup of blueberries weighs about 148 grams (5.22 oz), but the exact figure changes with how tightly it's packed and the brand. Scooping straight from the bag compacts blueberries and can leave you 15 to 20% over, so spoon it into the cup and level it off for the closest match to the figures above. Use the tables for quick reference, or the converter for any custom amount in cups, grams, ounces or tablespoons.
Tip: Toss blueberries in a little flour before folding them into batter to help suspend them and stop them sinking to the bottom of the bake.
