What is a Gram?

The gram is one thousandth of a kilogram and the primary everyday unit for measuring small masses in cooking, pharmacy, and retail. It equals approximately 0.0353 avoirdupois ounces. Nutrition labels worldwide list macronutrients in grams, and postal services use grams for lightweight items. A US nickel coin weighs exactly 5 grams, and a standard paper clip weighs about 1 gram.

What is a Kilogram?

The kilogram is the SI base unit of mass, redefined in 2019 by fixing the Planck constant to an exact numerical value of 6.62607015 × 10⁻³⁴ J·s — replacing the century-old physical platinum-iridium artifact. It is used worldwide for body weight, commercial goods, and scientific measurements. One kilogram equals exactly 2.20462 pounds. The kilogram is also the only SI base unit whose name includes a prefix.
