There are approximately 378 Candy Pumpkins in a gallon.
The Math / Science
We love candy at vCalc. We took al 11 ounce bag of Bach's Pumpkin shaped candies, measured it in a measuring cup and counted the kernels. We counted 40 candies at the 400 ml level of this measuring cup. Doing the math, that converts to 378 candies per gallon.
