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) = 1000 Megagram (Mg).
| Gigagram (Gg) | Megagram (Mg) |
|---|---|
| 0.1 | 100 |
| 0.5 | 500 |
| 1 | 1000 |
| 2 | 2000 |
| 5 | 5000 |
| 10 | 10000 |
| 25 | 25000 |
| 50 | 50000 |
| 100 | 100000 |
| 500 | 500000 |
| 1000 | 1000000 |
The gigagram is equal to 10⁹ grams or 1,000 tonnes (metric tons).
1 Gg = 10⁹ g = 10⁶ kg = 1,000 tonnes.
To convert Gg to tonnes: multiply by 1,000. To convert Gg to kg: multiply by 10⁶.
National emissions reports, large mining output figures, and major commodity trade volumes.
The Great Pyramid of Giza has an estimated mass of about 6,000 Gg (6 million tonnes).
Confusing Gg (gigagram) with GB (gigabyte). In mass contexts, G always means giga = 10⁹.
1 Gg = 1 kilotonne = 1,000 tonnes. Used when 'tonnes' gets unwieldy for very large masses.
The megagram is equal to 1,000 kilograms or one million grams — equivalent to one metric ton (tonne).
1 Mg = 1,000 kg = 10⁶ g = 1 tonne = 2,204.62 lb.
To convert Mg to kg: multiply by 1,000. To convert Mg to short tons: multiply by 1.10231.
Vehicle weights, cargo shipping, bulk commodities, and industrial material quantities.
A small car weighs about 1–1.5 Mg. An adult elephant weighs about 5–6 Mg.
Case sensitivity: Mg (megagram) vs. mg (milligram) differ by 10⁹! Always check capitalization.
1 Mg = 1 tonne = 1,000 kg. Think of a small car's weight as an anchor for this unit.
