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.
Stone (Uk)
A stone (st) is a British unit of weight equal to 14 pounds avoirdupois, primarily used for measuring body weight.
History/Origin
The stone has origins in medieval England, where it was used as a practical unit of weight for trade and commerce. Its use has persisted in the UK for measuring human body weight, despite the metric system's adoption elsewhere.
Current Use
Today, the stone is still commonly used in the UK and Ireland for personal weight measurement, especially in the context of health and fitness, although it is largely replaced by kilograms in official and international contexts.
