Grams to Cups: Popcorn Kernels
If your recipe is written in cups but your scale reads grams — or the other way round — this page solves the conversion for popcorn kernels. One cup of popcorn kernels weighs about 200 grams, which works out to a density of 0.85 g/ml. From there, half a cup is roughly 100 g, a quarter cup about 50 g, and one tablespoon about 13 g.
Converting between weight and volume depends on density, and density is specific to each ingredient: a cup of popcorn kernels does not weigh the same as a cup of flour or sugar. That is why this tool uses the measured density of popcorn kernels rather than a one-size-fits-all figure.
