How to Convert Teragram to Petagram
To convert Tg to tonnes: multiply by 10⁶. To convert Tg to Gg: multiply by 1,000.
1 Tg = 10¹² g = 10⁹ kg = 10⁶ tonnes = 1 megatonne.
For example, 1 Teragram (Tg) = 0.001 Petagram (Pg).

About Teragram (Tg)
The teragram equals 10¹² grams or one million tonnes (one megatonne).
1 Tg = 10¹² g = 10⁹ kg = 10⁶ tonnes = 1 megatonne.
To convert Tg to tonnes: multiply by 10⁶. To convert Tg to Gg: multiply by 1,000.
Global carbon budgets (~10,000 Tg C/year from fossil fuels), volcanic eruption plume masses.
Earth's atmosphere has a total mass of about 5.15 × 10⁶ Tg (5.15 × 10¹⁸ kg).
Confusing Tg with Pg (petagram): 1 Pg = 1,000 Tg. Climate papers use both — check carefully.
Global CO₂ emissions ≈ 36,000 Tg/year (or 36 Pg/year). This is a key climate number to remember.
