How to Convert Teragram to Neutron Mass
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) = 5.970408e+35 Neutron Mass (mn).

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 Neutron Mass (mn)
Definition
The neutron mass is the rest mass of a neutron, approximately 1.675 × 10⁻²⁷ kilograms, slightly heavier than a proton.
Mathematical Relationship
mn = mp + 1.293 MeV/c². About 0.14% heavier than a proton.
Conversion Formula
To convert neutron masses to kg: multiply by 1.67492749804 × 10⁻²⁷.
Practical Applications
Nuclear reactor design, neutron radiography, and neutron activation analysis for material composition.
Interesting Facts
A free neutron decays into a proton, electron, and antineutrino in about 14.7 minutes. Inside a nucleus, it can be stable for billions of years.
Common Mistakes
Assuming neutrons and protons have exactly the same mass — the neutron is 0.14% heavier, which is critical for nuclear stability.
Educational Tips
The mn > mp mass difference allows neutron beta decay (n → p + e⁻ + ν̄ₑ). Without it, atomic nuclei as we know them wouldn't exist.
