About these units
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.
Attogram (ag)
An attogram is 10⁻¹⁸ grams, an incredibly small mass used only in advanced scientific settings. At this scale, we are dealing with masses comparable to large molecules, viruses, or clusters of atoms. Modern techniques such as atomic force microscopy, mass spectrometry, and nanoscale resonators allow detection of attogram-level changes. Researchers studying chemical reactions, nanotechnology, and molecular biology may use attograms when describing ultra-fine mass differences. The attogram is an example of scientific progress: a unit unnecessary in the past, but now essential for understanding the smallest measurable interactions in nature.
