Hectogram
A hectogram (hg) is a unit of mass equal to 100 grams.
History/Origin
The hectogram is part of the metric system, introduced in the 19th century as a decimal-based system for standardizing measurements, primarily used in scientific and everyday contexts.
Current Use
The hectogram is used in some countries for measuring food and other small quantities, especially in the context of nutrition labels and grocery shopping, but is less common than grams and kilograms.
Attogram
An attogram (ag) is a unit of mass equal to 10^-18 grams, used to measure extremely small quantities.
History/Origin
The attogram was introduced as part of the metric system's expansion to include smaller units for scientific measurements, particularly in fields like nanotechnology and molecular biology, during the 20th century.
Current Use
Attograms are primarily used in scientific research to quantify very small masses, such as individual molecules or nanoparticles, and are part of the SI units for precise measurements in advanced scientific applications.
