How to Convert Teragram to Hectogram
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) = 10000000000 Hectogram (hg).

About Teragram (Tg)
Definition
The teragram equals 10¹² grams or one million tonnes (one megatonne).
Mathematical Relationship
1 Tg = 10¹² g = 10⁹ kg = 10⁶ tonnes = 1 megatonne.
Conversion Formula
To convert Tg to tonnes: multiply by 10⁶. To convert Tg to Gg: multiply by 1,000.
Practical Applications
Global carbon budgets (~10,000 Tg C/year from fossil fuels), volcanic eruption plume masses.
Interesting Facts
Earth's atmosphere has a total mass of about 5.15 × 10⁶ Tg (5.15 × 10¹⁸ kg).
Common Mistakes
Confusing Tg with Pg (petagram): 1 Pg = 1,000 Tg. Climate papers use both — check carefully.
Educational Tips
Global CO₂ emissions ≈ 36,000 Tg/year (or 36 Pg/year). This is a key climate number to remember.
About Hectogram (hg)
Definition
The hectogram is a unit of mass equal to 100 grams or one tenth of a kilogram.
Mathematical Relationship
1 hg = 100 g = 0.1 kg = 10 dag = 3.527 oz.
Conversion Formula
To convert hg to grams: multiply by 100. To convert hg to kg: divide by 10.
Practical Applications
Italian food shopping (un etto di prosciutto = 100 g of ham). Occasionally in European nutrition contexts.
Interesting Facts
In Italy, 'un etto' (one hectogram = 100 g) is the standard portion unit at deli counters.
Common Mistakes
Rarely encountered outside Italy, so people may not recognize it. 1 hg = 100 g = 0.1 kg.
Educational Tips
In Italy, 'un etto' = 100 g. The 'per 100 g' column on nutrition labels is essentially 'per hectogram'.
