Tonne: The tonne, also known as the metric ton, is a unit of mass in the metric system. It is equal to 1,000 kilograms or 1,000,000 grams. It is widely used internationally for measuring larger quantities of mass and is equivalent to approximately 2,204.62 pounds.
A milligram (mg) is a unit of mass in the metric system and the International System of Units (SI). It is equal to one one-thousandth of a gram, which means that 1 milligram is equivalent to 0.001 grams. The milligram is a small unit of mass commonly used for measuring very small quantities of substances, especially in scientific, medical, and pharmaceutical contexts.
For example, when you see the dosage of a medication listed on a prescription or on over-the-counter drugs, it is often measured in milligrams. Additionally, in laboratory settings, chemicals and substances are frequently measured in milligrams due to its precision in measuring small quantities.
