How to Convert Exagram to Attogram
To convert Eg to kg: multiply by 10¹⁵. To convert Eg to Pg: multiply by 1,000.
1 Eg = 10¹⁸ g = 10¹⁵ kg = 10⁹ tonnes.
For example, 1 Exagram (Eg) = 1.000000e+36 Attogram (ag).

About Exagram (Eg)
Definition
The exagram equals 10¹⁸ grams or 10¹⁵ kilograms — one trillion tonnes.
Mathematical Relationship
1 Eg = 10¹⁸ g = 10¹⁵ kg = 10⁹ tonnes.
Conversion Formula
To convert Eg to kg: multiply by 10¹⁵. To convert Eg to Pg: multiply by 1,000.
Practical Applications
No everyday applications. Describes masses of small moons or large asteroids.
Interesting Facts
Earth's total mass is about 5.97 × 10⁶ Eg. The entire atmosphere weighs 'only' about 5 Eg.
Common Mistakes
Hardly ever encountered — most contexts use 'times 10^x kg' notation instead of exagrams.
Educational Tips
If you need to express masses between Pg and Earth-masses, the exagram fills that gap: 1 Eg = 10¹⁵ kg.
About Attogram (ag)
Definition
The attogram is a unit of mass equal to 10⁻¹⁸ grams or 10⁻²¹ kilograms — one quintillionth of a gram.
Mathematical Relationship
1 ag = 10⁻¹⁸ g = 10⁻²¹ kg. A single HIV virus has a mass of about 10¹⁰ ag.
Conversion Formula
To convert ag to kg: multiply by 10⁻²¹. To convert kg to ag: multiply by 10²¹.
Practical Applications
Measuring masses of individual nanoparticles, viruses, and large biomolecules in nanosensor research.
Interesting Facts
In 2012, researchers achieved single-proton sensitivity (1.67 × 10⁻⁶ ag) using carbon nanotube resonators.
Common Mistakes
Confusing atto (10⁻¹⁸) with femto (10⁻¹⁵) — they differ by a factor of 1,000.
Educational Tips
Follow the prefix chain down: milli, micro, nano, pico, femto, atto — each step is 1,000× smaller.
