Convert gram to attogram
Please provide values below to convert gram [g] to attogram [ag], or Convert attogram to gram.
1 g = 1.0000e+18 ag. To convert gram to attogram, multiply the value by 1.0000e+18; to go the other way, divide by it (1 ag = 1.0000e-18 g). 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 g = 1.0000e+18 ag
- 1 ag = 1.0000e-18 g
- 10 g = 1.0000e+19 ag
- 100 g = 1.0000e+20 ag
How to Convert Gram to Attogram
1 g = 1e+18 ag
Example: convert 15 g to ag:
15 g = 15 × 1e+18 ag = 1.5e+19 ag

Gram
The gram (g) is a metric unit of mass equal to one thousandth of a kilogram.
History/Origin
The gram was originally defined in 1795 as the mass of one cubic centimeter of water at its maximum density. It became part of the metric system established in France and was later standardized as part of the International System of Units (SI) in 1960.
Current Use
The gram is widely used worldwide for measuring small masses in everyday life, science, and industry, especially in contexts like food labeling, pharmaceuticals, and laboratory measurements.
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.
