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 Petagram (Pg)
Definition
The petagram equals 10¹⁵ grams or one billion tonnes (one gigatonne).
Mathematical Relationship
1 Pg = 10¹⁵ g = 10¹² kg = 10⁹ tonnes = 1 gigatonne.
Conversion Formula
To convert Pg to tonnes: multiply by 10⁹. To convert Pg to Tg: multiply by 1,000.
Practical Applications
Global carbon budgets: about 10 Pg of carbon are emitted annually from fossil fuels.
Interesting Facts
The total mass of all life on Earth is estimated at about 550 Pg of carbon.
Common Mistakes
Confusing Pg (petagram = 10¹⁵ g) with PB (petabyte). In mass contexts, P = peta = 10¹⁵.
Educational Tips
1 Pg C = 1 gigatonne of carbon. Annual human CO₂ emissions are about 10 Pg C — a key climate figure.
