A teragram (Tg) is a unit of mass in the metric system, specifically in the International System of Units (SI). It represents one trillion grams or 10^12 grams. The metric system is a decimal-based system of measurement used worldwide, and it offers a convenient way to express both large and small quantities of mass.
To give you a sense of scale, here are some common mass comparisons involving the teragram:
Teragrams are typically used in scientific and environmental contexts, especially when discussing large quantities of substances like water, soil, or air pollutants. For example, the total mass of carbon stored in forests on Earth might be expressed in teragrams, or the annual emissions of a greenhouse gas could be measured in teragrams per year.
Grain: The grain is a unit of mass primarily used for measuring the weight of small objects or quantities, especially in the context of bullets, ammunition, and some food products. One grain is approximately equal to 0.0648 grams.
