How much does a 747 engine weigh?

A Boeing 747 typically uses engines that weigh between 8,000 to 10,000 pounds (approximately 3,600 to 4,500 kilograms) each, depending on the specific engine model. For example, the Pratt & Whitney PW4000 engines used on some 747 variants weigh around 9,000 pounds (about 4,080 kilograms) each.
