Convert femtogram to stone (US)
Please provide values below to convert femtogram [fg] to stone (US) [st (US)], or Convert stone (US) to femtogram.
1 fg = 1.5747e-19 st (US). To convert femtogram to stone (US), multiply the value by 1.5747e-19; to go the other way, divide by it (1 st (US) = 6.3503e+18 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 = 1.5747e-19 st (US)
- 1 st (US) = 6.3503e+18 fg
- 10 fg = 1.5747e-18 st (US)
- 100 fg = 1.5747e-17 st (US)
How to Convert Femtogram to Stone (Us)

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.
Stone (Us)
A stone (st) is a unit of weight primarily used in the United States, equal to 14 pounds or approximately 6.35 kilograms.
History/Origin
The stone has origins in medieval England, where it was used as a convenient weight measure for trade and commerce. Its value varied regionally before standardization, and it has been used historically for measuring human body weight and other goods.
Current Use
Today, the stone is mainly used in the UK and Ireland for body weight measurement, while in the United States, it is rarely used and often replaced by pounds or kilograms in most contexts.
