About these units
Petagram (Pg)
A petagram, equal to 10¹² kilograms, is used almost exclusively in global environmental science and earth system modeling. Planetary-scale carbon budgets—for example, the total carbon stored in Earth's soils or forests—are expressed in petagrams. The Amazon rainforest alone holds on the order of 100 Pg of carbon. Using petagrams helps researchers track changes in Earth's climate balance and evaluate feedback loops in the carbon cycle.
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.
