What is a grain (gr)?

A grain is a traditional mass unit equal to exactly 64.79891 milligrams, commonly used for bullet weights and historic pharmaceutical dosages.

How large is a gigagram (Gg)?

A gigagram is equal to one billion grams, or one million kilograms, typically used to express very large masses like greenhouse gas emissions.

Why convert from grain to gigagram?

Converting from grain to gigagram helps relate very small traditional weights to large-scale mass measurements for fields such as environmental science and bulk material accounting.
