How to Convert Earth's Mass to Long Ton (UK)
To convert Earth masses to kg: multiply by 5.9722 × 10²⁴.
M⊕ = 5.9722 × 10²⁴ kg ≈ 5.972 Yg (yottagrams). Earth = 1 M⊕ by definition.
For example, 1 Earth's Mass (M⊕) = 5.877878e+21 Long Ton (UK) (ton (UK)).

About Earth's Mass (M⊕)
Definition
The Earth mass is the mass of planet Earth, approximately 5.972 × 10²⁴ kilograms.
Mathematical Relationship
M⊕ = 5.9722 × 10²⁴ kg ≈ 5.972 Yg (yottagrams). Earth = 1 M⊕ by definition.
Conversion Formula
To convert Earth masses to kg: multiply by 5.9722 × 10²⁴.
Practical Applications
Expressing exoplanet masses (e.g., 'a planet of 3 Earth masses'), moon masses, and asteroid masses.
Interesting Facts
Earth gains about 40,000 tonnes of mass per year from cosmic dust — but that's only 10⁻¹⁷ of its total mass.
Common Mistakes
Earth's mass is hard to visualize. The key insight: it's known from G × M⊕ (the gravitational parameter), not M⊕ alone.
Educational Tips
Cavendish 'weighed the Earth' by measuring G. If you know g (9.8 m/s²) and Earth's radius, you can calculate M⊕ = gR²/G.
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).
