Overview
Popcorn kernels contain a tiny drop of water that turns into steam when heated, causing the starch to explode outward. This calculator predicts the final volume and nutritional value of your snack.

Pro Tips
1/4 cup of kernels yields approximately 7-8 cups of popped popcorn.
Air-popping is the healthiest method as it requires no added oil.
If using a stovetop, add 1-2 tablespoons of high-smoke-point oil (like coconut or canola) per 1/2 cup of kernels.
Keep your kernels in a tightly sealed container to maintain their moisture level—dry kernels won't pop!
