How to Convert Gigagram to Exagram
To convert Gg to tonnes: multiply by 1,000. To convert Gg to kg: multiply by 10⁶.
1 Gg = 10⁹ g = 10⁶ kg = 1,000 tonnes.
For example, 1 Gigagram (Gg) = 1.000000e-9 Exagram (Eg).
Gigagram to Exagram — Common Values

|---|---|
| 0.1 | 1.000000e-10 |
| 0.5 | 5.000000e-10 |
| 1 | 1.000000e-9 |
| 2 | 2.000000e-9 |
| 5 | 5.000000e-9 |
| 10 | 1.000000e-8 |
| 25 | 2.500000e-8 |
| 50 | 5.000000e-8 |

About Gigagram (Gg)
Definition
The gigagram is equal to 10⁹ grams or 1,000 tonnes (metric tons).
Mathematical Relationship
1 Gg = 10⁹ g = 10⁶ kg = 1,000 tonnes.
Conversion Formula
To convert Gg to tonnes: multiply by 1,000. To convert Gg to kg: multiply by 10⁶.
Practical Applications
National emissions reports, large mining output figures, and major commodity trade volumes.
Interesting Facts
The Great Pyramid of Giza has an estimated mass of about 6,000 Gg (6 million tonnes).
Common Mistakes
Confusing Gg (gigagram) with GB (gigabyte). In mass contexts, G always means giga = 10⁹.
Educational Tips
1 Gg = 1 kilotonne = 1,000 tonnes. Used when 'tonnes' gets unwieldy for very large masses.
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.
