The gram or gramme (Greek/Latin root grámma) symbol g, is a unit of mass.

[edit] Examples
All masses are approximate:

Plastic pen cap (Bic): 1 gram
A single Smartie: 1 gram
Paper clip: 0.5 grams to 1.5 grams
Typical sheet of A4 paper: 5 grams
1 US banknote (any denomination): 1 gram[1]
United States nickel - 5 grams (very accurate when new)

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

[edit] 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.

[edit] Conversion factors

1 grain = 0.06479891 gram
1 ounce (avoirdupois) = 28.349523125 grams
1 ounce (troy) = 31.1034768 grams
