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.
Petagram
A petagram (Pg) is a unit of mass equal to 10^15 grams or one quadrillion grams.
History/Origin
The petagram was introduced as part of the metric system's prefixes to represent extremely large masses, following the adoption of the International System of Units (SI). It is derived from the prefix 'peta-' which denotes 10^15.
Current Use
The petagram is primarily used in scientific contexts to quantify very large masses, such as in astronomy and geology, but is rarely used in everyday measurements.
