About the pound and the gram
The pound
The international avoirdupois pound (lb) is a unit of mass in the imperial and US customary systems, defined as exactly 0.45359237 kilograms since the 1959 international yard and pound agreement. It is the everyday unit for body weight, groceries, and shipping in the United States. Sixteen ounces make one pound; fourteen pounds make one stone in British usage.
The gram
The gram (g) is a metric unit of mass equal to one-thousandth of a kilogram. It is the everyday unit for food labeling, postage, jewelry, and laboratory measurements. The 2019 SI redefinition fixed the kilogram (and therefore the gram) in terms of Planck's constant, ending more than a century of dependence on a physical prototype.
