How to Convert Proton Mass to Long Ton (UK)
To convert proton masses to kg: multiply by 1.67262192369 × 10⁻²⁷.
mp ≈ 1,836 × mₑ ≈ 1.00728 u. About 0.1% heavier than a neutron.
For example, 1 Proton Mass (mp) = 1.646205e-30 Long Ton (UK) (ton (UK)).

About Proton Mass (mp)
Definition
The proton mass is the rest mass of a proton, approximately 1.673 × 10⁻²⁷ kilograms or about 938.3 MeV/c².
Mathematical Relationship
mp ≈ 1,836 × mₑ ≈ 1.00728 u. About 0.1% heavier than a neutron.
Conversion Formula
To convert proton masses to kg: multiply by 1.67262192369 × 10⁻²⁷.
Practical Applications
Nuclear energy calculations, radiation therapy dosimetry, and proton beam therapy for cancer.
Interesting Facts
A proton's mass is mostly from the kinetic energy of quarks and gluons (via E=mc²), not from the quark masses themselves (~1%).
Common Mistakes
Assuming quarks make up most of the proton's mass — quarks contribute only ~1%. The rest is binding energy.
Educational Tips
The proton:electron mass ratio (1,836:1) is a fundamental number in physics. It determines atomic structure.
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).
