Femtogram
A femtogram (fg) is a unit of mass equal to 10^-15 grams.
History/Origin
The femtogram was introduced as part of the metric system's extension to measure extremely small masses, particularly in scientific fields such as chemistry and biology, during the 20th century as measurement technology advanced.
Current Use
Femtograms are used in scientific research to measure tiny quantities of substances, such as in molecular biology, nanotechnology, and materials science, where precise measurement of very small masses is required.
