How Many Ounces Are in a Hershey's Kiss?
A single standard Hershey's Kiss weighs 0.16 ounces. Because the recommended serving size of Hershey's Kisses is 1.45 ounces, or 9 pieces, simply divide 1.45 ounces by 9 to come up with the weight of an individual Kiss.
The most common 0.16-ounce Hershey Kiss has been around since 1907 in a relatively unchanged state. However, there are many larger sizes sold by the company, including one that weighs 2 pounds. None of these are as large as the Kiss Hershey created to commemorate the company's 100th anniversary in 2007. The commemorative chocolate candy weighed a world record 30,540 pounds, the equivalent of six pick-up trucks.
