How to Convert Short Ton (US) to Earth's Mass
To convert short tons to kg: multiply by 907.185. To convert short tons to metric tonnes: multiply by 0.9072.
1 short ton = 2,000 lb = 907.18474 kg = 0.90718 metric tonnes.
For example, 1 Short Ton (US) (ton (US)) = 1.519013e-22 Earth's Mass (M⊕).

About Short Ton (US) (ton (US))
Definition
The short ton (US ton) is a unit of mass equal to 2,000 pounds or approximately 907.185 kilograms.
Mathematical Relationship
1 short ton = 2,000 lb = 907.18474 kg = 0.90718 metric tonnes.
Conversion Formula
To convert short tons to kg: multiply by 907.185. To convert short tons to metric tonnes: multiply by 0.9072.
Practical Applications
Coal mining output, grain production, truck payload limits, and US shipping and freight.
Interesting Facts
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).
Common Mistakes
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.
Educational Tips
Remember: short ton = 2,000 lb, long ton = 2,240 lb, metric tonne = 2,205 lb. The metric tonne is between the other two.
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.
