Convert grain to petagram
Please provide values below to convert grain [gr] to petagram [Pg], or Convert petagram to grain.
1 gr = 6.4799e-17 Pg. To convert grain to petagram, multiply the value by 6.4799e-17; to go the other way, divide by it (1 Pg = 1.5432e+16 gr). Both units measure weight and mass and appear in everyday as well as technical calculations, so switching between them quickly is often useful.
Quick Reference
- 1 gr = 6.4799e-17 Pg
- 1 Pg = 1.5432e+16 gr
- 10 gr = 6.4799e-16 Pg
- 100 gr = 6.4799e-15 Pg
How to Convert Grain to Petagram
1 gr = 6.479891e-17 Pg
Example: convert 15 gr to Pg:
15 gr = 15 × 6.479891e-17 Pg = 9.7198365e-16 Pg

Grain
A grain is a unit of mass traditionally used to measure small quantities, primarily in the context of precious metals, pharmaceuticals, and firearms.
History/Origin
The grain dates back to ancient times and was originally based on the weight of a single seed of a cereal grain, such as barley. It has been used since the Middle Ages and was standardized in the apothecaries' system.
Current Use
Today, the grain is mainly used in the measurement of bullets, gunpowder, and precious metals, and is recognized as a unit of mass in the apothecaries' system, although it has largely been replaced by grams in most contexts.
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.
