To convert tonnes to kg: multiply by 1,000. To convert tonnes to short tons: multiply by 1.10231.
1 t = 1,000 kg = 10⁶ g = 2,204.62 lb = 1.10231 short tons = 0.98421 long tons.
For example, 1 Metric Ton (t) = 5.028992e-28 Sun's Mass (M☉).

The metric ton (tonne) is a unit of mass equal to 1,000 kilograms or one megagram.
1 t = 1,000 kg = 10⁶ g = 2,204.62 lb = 1.10231 short tons = 0.98421 long tons.
To convert tonnes to kg: multiply by 1,000. To convert tonnes to short tons: multiply by 1.10231.
Cargo shipping, vehicle weight ratings, construction material ordering, and agricultural harvests.
The three 'tons' often cause confusion: metric tonne (1,000 kg), short ton (907 kg, US), and long ton (1,016 kg, UK).
Confusing metric tonnes with short tons (US) or long tons (UK). A metric tonne is 10% heavier than a US short ton.
1 tonne = ~2,200 lb. Quick check: multiply tonnes by 2.2 to get approximate thousands of pounds.
The solar mass is the mass of the Sun, approximately 1.989 × 10³⁰ kilograms — about 333,000 times the mass of Earth.
M☉ = 1.98847 × 10³⁰ kg ≈ 333,000 M⊕ ≈ 1,048 M_Jupiter.
To convert solar masses to kg: multiply by 1.98847 × 10³⁰.
Expressing stellar masses: Betelgeuse ≈ 15 M☉, Sirius ≈ 2 M☉, a typical neutron star ≈ 1.4 M☉.
The Sun loses about 5 million tonnes per second through nuclear fusion (E=mc²), but that's only 10⁻¹³ M☉ per year.
The Sun is losing mass continuously through radiation and solar wind — its mass is not quite constant over billions of years.
Almost everything in astronomy uses solar masses: stars (0.1–100 M☉), galaxies (10⁹–10¹² M☉), black holes (3–10⁹ M☉).
