How to Convert Teragram to Centigram
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) = 1.000000e+14 Centigram (cg).

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 Centigram (cg)
Definition
The centigram is a unit of mass equal to one hundredth of a gram (10⁻² g) or 10 milligrams.
Mathematical Relationship
1 cg = 0.01 g = 10 mg = 10,000 µg.
Conversion Formula
To convert cg to mg: multiply by 10. To convert cg to grams: divide by 100.
Practical Applications
Occasionally used in older pharmaceutical and chemical references. Most modern use has shifted to mg.
Interesting Facts
The centigram is one of the least-used metric prefixed mass units, overshadowed by the more practical milligram.
Common Mistakes
Because it's so rarely used, people may not recognize 'cg' — convert to mg for clarity in communication.
Educational Tips
Centi = hundredth: just as 1 cm = 0.01 m, 1 cg = 0.01 g. The pattern is consistent across all SI units.
