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) = 4.594672e+13 Planck Mass (mₚ).

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 Planck mass is the fundamental natural unit of mass, approximately 2.176 × 10⁻⁸ kg (about 21.76 micrograms).
mₚ = √(ℏc/G) ≈ 2.176 × 10⁻⁸ kg ≈ 21.76 µg ≈ 1.31 × 10¹⁹ proton masses.
To convert Planck masses to kg: multiply by 2.176434 × 10⁻⁸.
No direct practical applications — a Planck mass is roughly the mass of a flea egg, but its significance is theoretical.
Unusually, the Planck mass is macroscopic (~22 µg) — about the mass of a flea egg, a grain of sand, or a small dust mite.
Expecting Planck mass to be extremely small like other Planck units — it's actually macroscopic (~22 µg).
Other Planck units are absurdly small or large, but the Planck mass is surprisingly human-scale: about 20 micrograms.
