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) = 984206.5276 Long Ton (UK) (ton (UK)).

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.
The long ton (imperial ton) is a unit of mass equal to 2,240 pounds or approximately 1,016 kilograms.
1 long ton = 2,240 lb = 1,016.047 kg = 1.016 metric tonnes = 1.12 short tons.
To convert long tons to kg: multiply by 1,016.047. To convert long tons to short tons: multiply by 1.12.
Ship displacement tonnage (historical, some naval vessels still use it), and some UK agricultural contexts.
Naval ship displacement is traditionally given in long tons. HMS Titanic displaced about 52,310 long tons.
Assuming a 'ton' is a 'ton' — the long ton is 12% heavier than a short ton and 1.6% heavier than a metric tonne.
Easy memory: Long ton = British = 2,240 lb (long = larger). Short ton = US = 2,000 lb (short = smaller).
