The Story of Letter G
The letter G was created a very long time ago, in the third century BC. A Roman named Spurius Carvilius Ruga invented it. Before G existed, the letter C was used for two different sounds. It could sound like the "c" in "cat" or like the "g" in "girl." To make things clearer and give each sound its own letter, Ruga came up with the letter G.
What G Can Mean

- In the SI, which is a worldwide system for measurements, a lowercase g is the symbol for the gram. A gram is a very small unit of mass.
