Popcorn kernels: US, metric & UK cups compared
A “cup” isn’t the same size everywhere, so 1 cup of popcorn kernels 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 popcorn kernels in each:
| Cup standard | Size | 1 cup popcorn kernels | Used in |

So 100g of popcorn kernels is about 0.5 cups, 200g is about 1 cups, 250g is about 1.25 cups, and 300g is about 1.5 cups.

How to measure popcorn kernels accurately
For the most reliable baking results, weigh popcorn kernels on a kitchen scale rather than scooping by volume. One US cup of popcorn kernels weighs about 200 grams (7.05 oz), but the exact figure changes with how tightly it's packed and the brand. Scooping straight from the bag compacts popcorn kernels 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: Just ¼ cup of kernels makes a big bowl of popcorn — about 8 cups popped — so measure the unpopped kernels sparingly.
