Convert attogram to stone (US)
Please provide values below to convert attogram [ag] to stone (US) [st (US)], or Convert stone (US) to attogram.
1 ag = 1.5747e-22 st (US). To convert attogram to stone (US), multiply the value by 1.5747e-22; to go the other way, divide by it (1 st (US) = 6.3503e+21 ag). 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 ag = 1.5747e-22 st (US)
- 1 st (US) = 6.3503e+21 ag
- 10 ag = 1.5747e-21 st (US)
- 100 ag = 1.5747e-20 st (US)
How to Convert Attogram to Stone (Us)
1 ag = 1.5747304441777e-22 st (US)
Example: convert 15 ag to st (US):
15 ag = 15 × 1.5747304441777e-22 st (US) = 2.36209566626655e-21 st (US)

Attogram
An attogram (ag) is a unit of mass equal to 10^-18 grams, used to measure extremely small quantities.
History/Origin
The attogram was introduced as part of the metric system's expansion to include smaller units for scientific measurements, particularly in fields like nanotechnology and molecular biology, during the 20th century.
Current Use
Attograms are primarily used in scientific research to quantify very small masses, such as individual molecules or nanoparticles, and are part of the SI units for precise measurements in advanced scientific applications.
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.
