To convert muon masses to kg: multiply by 1.883531627 × 10⁻²⁸.
mμ ≈ 206.77 × mₑ ≈ 0.1126 × mₚ (proton mass) = 105.66 MeV/c².
For example, 1 Muon Mass (mμ) = 1.883532e-37 Teragram (Tg).

The muon mass is the rest mass of the muon particle, approximately 1.884 × 10⁻²⁸ kilograms or about 207 times the electron mass.
mμ ≈ 206.77 × mₑ ≈ 0.1126 × mₚ (proton mass) = 105.66 MeV/c².
To convert muon masses to kg: multiply by 1.883531627 × 10⁻²⁸.
Muon tomography (imaging volcanoes, pyramids), muon-catalyzed fusion, and cosmic ray detection.
The muon's discovery prompted physicist I.I. Rabi to quip 'Who ordered that?' — it was completely unexpected.
Muons are not mesons — they're leptons (like electrons), not quark-antiquark pairs.
Think of a muon as a 'fat electron' — same charge, same spin, but 207× heavier. It decays in about 2.2 microseconds.
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.
