Convert kilogram to attogram
Please provide values below to convert kilogram [kg] to attogram [ag], or Convert attogram to kilogram.
1 kg = 1.0000e+21 ag. To convert kilogram to attogram, multiply the value by 1.0000e+21; to go the other way, divide by it (1 ag = 1.0000e-21 kg). 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 kg = 1.0000e+21 ag
- 1 ag = 1.0000e-21 kg
- 10 kg = 1.0000e+22 ag
- 100 kg = 1.0000e+23 ag
How to Convert Kilogram to Attogram
1 kg = 1e+21 ag
Example: convert 15 kg to ag:
15 kg = 15 × 1e+21 ag = 1.5e+22 ag

Kilogram
The kilogram (kg) is the base unit of mass in the International System of Units (SI), defined as the mass of the International Prototype Kilogram, a platinum-iridium alloy cylinder kept at the International Bureau of Weights and Measures.
History/Origin
The kilogram was originally defined in 1795 as the mass of one liter of water. It was later represented by a platinum standard in 1875, known as the International Prototype Kilogram, which served as the global standard until 2019.
Current Use
Today, the kilogram is defined by the Planck constant, fixed at exactly 6.62607015×10⁻³⁴ joule seconds, ensuring greater precision and stability in measurements worldwide. It is widely used in science, industry, and commerce for measuring mass.
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.
