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 Femtogram (fg)
Definition
The femtogram is a unit of mass equal to 10⁻¹⁵ grams or 10⁻¹⁸ kilograms — one quadrillionth of a gram.
Mathematical Relationship
1 fg = 10⁻¹⁵ g = 10⁻¹⁸ kg = 1,000 ag.
Conversion Formula
To convert fg to kg: multiply by 10⁻¹⁸. To convert fg to pg: divide by 1,000.
Practical Applications
Expressing the mass of individual bacterial cells (~100 fg for E. coli) and subcellular components.
Interesting Facts
A single E. coli bacterium has a mass of about 600–700 fg. A single mitochondrion is roughly 1 fg.
Common Mistakes
Mixing up fg (femtogram) with fm (femtometer) — one is mass, the other is length.
Educational Tips
A bacterium weighs ~500 fg — this gives you a tangible anchor for the femtogram scale.
