Why sweetened condensed milk needs its own conversion
Sweetened Condensed Milk weighs about 306g per cup — notably dense — closer to syrups than most dry ingredients. USDA = ~306 g/cup; King Arthur 1/4 cup = 78 g (~312 g). One 14 oz can ~ 306-397 g depending on fill. A cup is a unit of volume, so ingredients this different in density can't share one generic conversion factor — using a single "1 cup = X g" rule for everything will be wrong for at least some of what you cook.
Common measurement mistakes
- Using a generic cup-to-gram factor for every ingredient — sweetened condensed milk does not weigh the same per cup as most other ingredients.
- Measurement note: USDA = ~306 g/cup; King Arthur 1/4 cup = 78 g (~312 g). One 14 oz can ~ 306-397 g depending on fill.
- Confusing weight ounces with fluid ounces when a recipe lists "oz" — they are not interchangeable.

It’s a close approximation based on USDA FoodData Central. Minor variations in moisture, grain, or brand can shift the exact weight slightly, but this figure works well for everyday cooking and baking.
