Final answer:
The U.S. Congress and businesses resist conversion to the metric system due to disruption and costs. The metric system uses powers of 10 for unit changes, while the U.S. Customary System has unrelated conversion factors.
Step-by-step explanation:
The U.S. Congress and businesses have been resisting conversion to the metric system because they fear the disruption and costs associated with the transition.
The metric system, also known as the International System of Units (SI), is widely used around the world, including in scientific research, engineering, and trade. The main difference between the metric system and the U.S. Customary System is that in the metric system, unit changes are based on powers of 10, while in the U.S. customary system, each unit conversion has unrelated conversion factors.
