Final answer:
It makes sense for people in the United States to use SI units in everyday life because they provide a standardized system of measurement and make calculations and conversions easier.
Step-by-step explanation:
Using SI units in everyday life in the United States makes sense because they provide a standardized and consistent system of measurement that is used worldwide. The SI base units, such as meter, kilogram, and second, are based on factors of 10, making calculations and conversions easier.
For example, if you want to convert a length from inches to meters, you would simply multiply by the conversion factor of 0.0254. Similarly, if you want to convert a weight from pounds to kilograms, you would multiply by the conversion factor of 0.4536.
