To convert solar masses to kg: multiply by 1.98847 × 10³⁰.
M☉ = 1.98847 × 10³⁰ kg ≈ 333,000 M⊕ ≈ 1,048 M_Jupiter.
For example, 1 Sun's Mass (M☉) = 2.191913e+27 Short Ton (US) (ton (US)).

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☉).
The short ton (US ton) is a unit of mass equal to 2,000 pounds or approximately 907.185 kilograms.
1 short ton = 2,000 lb = 907.18474 kg = 0.90718 metric tonnes.
To convert short tons to kg: multiply by 907.185. To convert short tons to metric tonnes: multiply by 0.9072.
Coal mining output, grain production, truck payload limits, and US shipping and freight.
The US short ton (2,000 lb) is about 10% lighter than a metric tonne (2,205 lb) and about 11% lighter than a UK long ton (2,240 lb).
Assuming 'ton' means the same thing everywhere. In the US it's 2,000 lb; in the UK it's 2,240 lb; in metric it's 2,205 lb.
Remember: short ton = 2,000 lb, long ton = 2,240 lb, metric tonne = 2,205 lb. The metric tonne is between the other two.
