About these units
Milligram (mg)
A milligram is one-thousandth of a gram and essential for measuring extremely small masses with precision. Pharmacology relies heavily on milligrams to dose medications safely and consistently—especially potent drugs where differences of a few milligrams can be critical. In chemistry and laboratory science, milligrams are used to weigh reagents, catalysts, micro-samples, and test materials. Environmental science uses milligrams per liter or milligrams per kilogram to describe concentrations of contaminants. Its small size makes the milligram ideal for fields requiring strict quantitative control, and its stability within the metric system ensures predictable conversions during calculations.
Kiloton (Metric) (kt)
A kiloton, equal to 1,000 metric tons, is used in large-scale industrial, geological, and agricultural contexts. However, the term is better known for expressing explosive yields, particularly of nuclear weapons. Scientists estimate the energy release of explosions by comparing them to the detonation of 1,000 tons of TNT. For example, the Hiroshima bomb had a yield of about 15 kilotons. Outside military contexts, kilotons appear in discussions of carbon emissions, waste production, and global resource extraction. They provide a manageable scale for describing quantities too large for tons but not yet at the megaton level.
