Understanding Weight Units

The Gram (g)

The gram is the base unit of mass in the metric system. Originally defined as the mass of one cubic centimeter of water at 4 degrees Celsius, it is now defined as one-thousandth of the International Prototype Kilogram. The gram is particularly useful for measuring small quantities and is the standard unit for food nutrition labels worldwide.

The Pound (lb)

The pound is a unit of mass in the imperial and US customary systems. The international avoirdupois pound is defined as exactly 453.59237 grams. The abbreviation "lb" comes from the Latin word "libra," which was an ancient Roman unit of measurement. There are 16 ounces in one pound.

The Ounce (oz)

The ounce is a smaller unit in the imperial system. One ounce equals approximately 28.3495 grams. It is commonly used for measuring smaller quantities, food portions, and precious metals. Note that the troy ounce used for precious metals (31.1035 grams) differs from the avoirdupois ounce.
