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.
Pennyweight: The pennyweight (abbreviated as dwt) is a unit of mass commonly used in the jewelry industry to measure the weight of precious metals, particularly gold and silver. One pennyweight is equal to 24 grains or approximately 1.555 grams.
