How to Convert Long Ton (UK) to Sun's Mass
To convert long tons to kg: multiply by 1,016.047. To convert long tons to short tons: multiply by 1.12.
1 long ton = 2,240 lb = 1,016.047 kg = 1.016 metric tonnes = 1.12 short tons.
For example, 1 Long Ton (UK) (ton (UK)) = 5.109692e-28 Sun's Mass (M☉).

About Long Ton (UK) (ton (UK))
Definition
The long ton (imperial ton) is a unit of mass equal to 2,240 pounds or approximately 1,016 kilograms.
Mathematical Relationship
1 long ton = 2,240 lb = 1,016.047 kg = 1.016 metric tonnes = 1.12 short tons.
Conversion Formula
To convert long tons to kg: multiply by 1,016.047. To convert long tons to short tons: multiply by 1.12.
Practical Applications
Ship displacement tonnage (historical, some naval vessels still use it), and some UK agricultural contexts.
Interesting Facts
Naval ship displacement is traditionally given in long tons. HMS Titanic displaced about 52,310 long tons.
Common Mistakes
Assuming a 'ton' is a 'ton' — the long ton is 12% heavier than a short ton and 1.6% heavier than a metric tonne.
Educational Tips
Easy memory: Long ton = British = 2,240 lb (long = larger). Short ton = US = 2,000 lb (short = smaller).
About Sun's Mass (M☉)
Definition
The solar mass is the mass of the Sun, approximately 1.989 × 10³⁰ kilograms — about 333,000 times the mass of Earth.
Mathematical Relationship
M☉ = 1.98847 × 10³⁰ kg ≈ 333,000 M⊕ ≈ 1,048 M_Jupiter.
Conversion Formula
To convert solar masses to kg: multiply by 1.98847 × 10³⁰.
Practical Applications
Expressing stellar masses: Betelgeuse ≈ 15 M☉, Sirius ≈ 2 M☉, a typical neutron star ≈ 1.4 M☉.
Interesting Facts
The Sun loses about 5 million tonnes per second through nuclear fusion (E=mc²), but that's only 10⁻¹³ M☉ per year.
Common Mistakes
The Sun is losing mass continuously through radiation and solar wind — its mass is not quite constant over billions of years.
Educational Tips
Almost everything in astronomy uses solar masses: stars (0.1–100 M☉), galaxies (10⁹–10¹² M☉), black holes (3–10⁹ M☉).
