How to Convert Short Ton (US) to Electron Mass (rest)
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)) = 9.958794e+32 Electron Mass (rest) (mₑ).

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 Electron Mass (rest) (mₑ)
Definition
The electron rest mass is the mass of a stationary electron, approximately 9.109 × 10⁻³¹ kilograms.
Mathematical Relationship
mₑ ≈ 9.109 × 10⁻³¹ kg = 5.486 × 10⁻⁴ u = 1/1836 of a proton mass.
Conversion Formula
To convert electron masses to kg: multiply by 9.1093837015 × 10⁻³¹.
Practical Applications
Essential for electron microscope design, semiconductor physics, and laser technology.
Interesting Facts
The electron is about 1,836 times lighter than a proton. An electron's mass-energy equivalent (E=mc²) is 0.511 MeV.
Common Mistakes
Confusing electron mass with electron charge (e). Mass = 9.1 × 10⁻³¹ kg; charge = 1.6 × 10⁻¹⁹ C.
Educational Tips
Key ratio: proton-to-electron mass ≈ 1,836. This ratio explains why electrons orbit nuclei rather than the reverse.
