What is a Gram (g)?

A gram is a metric unit of mass, defined as one-thousandth of a kilogram (1 g = 0.001 kg). It’s very small—a paperclip weighs about 1 gram. It’s used worldwide for food ingredients, gold, medicine, and small weights.

In everyday terms, a gram weighs about as much as:

• A standard paperclip
• A US dollar bill
• A raisin
• 1 milliliter of water

Though Americans use pounds for body weight, grams are everywhere in daily life—on nutrition labels, in baking recipes, for postage, jewelry, and all scientific measurements.

What is an Ounce (oz)?

An ounce is a US customary unit, used to measure weight or mass, especially for smaller quantities. It is defined as exactly 1/16th of a pound.

In the USA, it’s used for flour, sugar, coffee, and precious metals like gold and silver.

• 1 ounce (oz) = 1/16 pound (lb)
• 1 pound (lb) = 16 ounces (oz)
• 1 ounce (oz) ≈ 28.35 grams (g)
• 1 ounce (oz) ≈ 0.02835 kilograms (kg)

To visualize it, one ounce is roughly equal to:

• A slice of bread
• A standard pencil
• 2 tablespoons of liquid (for fluid ounces)
• 28 paperclips

Note: A weight ounce (oz) is different from a fluid ounce (fl oz), which measures volume rather than weight.
