About Grams (g)

The gram (symbol: g) is a unit of mass in the International System of Units (SI). It is defined as one thousandth of the kilogram (the SI base unit of mass). The gram was originally defined as the mass of one cubic centimeter of water at its maximum density (at 4°C).

The gram was introduced in France following the French Revolution. It was part of the original metric system. While the kilogram is now the base unit for mass, the gram remains a widely used and fundamental unit, especially for smaller quantities.

Grams are used globally for precise mass measurements in many fields:

• Cooking and baking recipes (e.g., 200 g of flour).
• Nutritional information on food packaging.
• Laboratory measurements in chemistry and biology.
• Measuring the mass of small objects, ingredients, and precious metals (though carats are often used for gemstones).
• Postage calculations for letters and small parcels.

• 1 gram (g) = 1,000 milligrams (mg)
• 1 gram (g) = 1,000,000 micrograms (µg)
• 1,000 grams (g) = 1 kilogram (kg)
• 1 gram (g) ≈ 0.035274 ounces (oz, avoirdupois)
• 1 gram (g) ≈ 0.00220462 pounds (lb, avoirdupois)

To help visualize a gram:

• A standard paperclip has a mass of about 1 gram.
• A United States dollar bill or a Euro banknote weighs approximately 1 gram.
• A small sugar cube can weigh around 2-4 grams.
• A raisin is often close to 1 gram.
