About Pound (lb)

An imperial unit of mass equal to 16 ounces, defined as exactly 0.45359237 kilograms by the 1959 international yard-and-pound agreement. The pound is the primary unit of body weight in the United States, the commercial unit for produce and meat ("$5.99 per pound"), and the standard for US shipping tariffs. Commonly abbreviated "lb" from the Latin libra. Pounds also measure aircraft weight in US aviation and are the native unit for barbell plates in US gyms.

About Ounce (oz)

An imperial unit of mass equal to 1/16 of a pound (approximately 28.35 grams).
