The gram or gramme (Greek/Latin root grámma) symbol g, is a unit of mass. It is defined as one one-thousandth of the SI base unit kilogram, or 1×10−3 kg.

  • plastic pen cap (Bic) is 1 gram
  • Smartie 1 gram
  • paper clip is 0.5 grams to 1.5 grams
  • A4 paper is 5 grams
  • 1 USD is 1 gram

History

It was the base unit of mass in the original French metric system and the later centimetre-gram-second (CGS) system of units.

Uses

The gram is today the most widely used unit of measurement for non-liquid ingredients in cooking and grocery shopping worldwide. For food products that are typically sold in quantities far less than 1 kg, the unit price is normally given per 100 g.

Most standards and legal requirements for nutrition labels on food products require relative contents to be stated per 100 g of the product, such that the resulting figure can also be read as a percentage.

  • 1 ounce (avoirdupois) = 28.349523125 grams
  • 1 ounce (troy) = 31.1034768 grams
