How do you calculate total weight in ounces?

To calculate total weight in ounces when you have the weight in pounds, the correct approach is to multiply the number of pounds by 16. This is because there are 16 ounces in a pound. Therefore, if you have a weight in pounds and you want to convert it to ounces, you enhance the total by multiplying by 16, effectively converting the higher unit (pounds) to the lower unit (ounces) for accurate measurement in a smaller unit.

The other options present incorrect calculations or misunderstand the conversion process, such as dividing ounces or using incorrect multipliers for pounds. Thus, the correct conversion methodology aligns with standard weight measurements in the imperial system.
