Convert femtogram to grain
Please provide values below to convert femtogram [fg] to grain [gr], or Convert grain to femtogram.
1 fg = 1.5432e-14 gr. To convert femtogram to grain, multiply the value by 1.5432e-14; to go the other way, divide by it (1 gr = 6.4799e+13 fg). 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 fg = 1.5432e-14 gr
- 1 gr = 6.4799e+13 fg
- 10 fg = 1.5432e-13 gr
- 100 fg = 1.5432e-12 gr

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.
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and precious metals, and is recognized as a unit of mass in the apothecaries' system, although it has largely been replaced by grams in most contexts.
