A **gigatonne****(gt**) is the equivalent of **1,000,000,000 tons** (factor:^{109}). A gigaton is therefore a unit of measurement for particularly heavy weights or masses. It is even larger than the kiloton (1,000 tons or^{103}) and the megaton (1,000,000 tons or^{106}).

A tonne is a metric unit of measurement for mass and corresponds to 1000 kilograms. The **gigatonne** is a much larger unit and is equal to **one billion tons**. In scientific notation, this is often expressed as **10^9 tons**.

To convert tons to gigatons, you divide the number of tons by a billion (10^9). So, for example, if you have 2 billion tons and want to know how many gigatons that is, you divide 2 billion by a billion to get 2 gigatons.

This is particularly useful in geology, climatology and astrophysics, where very large mass quantities are often used. For example, annual carbon dioxide emissions are often measured in gigatons to better represent the large amounts of CO2.

It is important to note that the metric system used internationally in science is based on powers of ten, which makes it easier to convert between different units.
