How to Convert Attogram to Long Ton (UK)
To convert ag to kg: multiply by 10⁻²¹. To convert kg to ag: multiply by 10²¹.
1 ag = 10⁻¹⁸ g = 10⁻²¹ kg. A single HIV virus has a mass of about 10¹⁰ ag.
For example, 1 Attogram (ag) = 9.842065e-25 Long Ton (UK) (ton (UK)).

About Attogram (ag)
Definition
The attogram is a unit of mass equal to 10⁻¹⁸ grams or 10⁻²¹ kilograms — one quintillionth of a gram.
Mathematical Relationship
1 ag = 10⁻¹⁸ g = 10⁻²¹ kg. A single HIV virus has a mass of about 10¹⁰ ag.
Conversion Formula
To convert ag to kg: multiply by 10⁻²¹. To convert kg to ag: multiply by 10²¹.
Practical Applications
Measuring masses of individual nanoparticles, viruses, and large biomolecules in nanosensor research.
Interesting Facts
In 2012, researchers achieved single-proton sensitivity (1.67 × 10⁻⁶ ag) using carbon nanotube resonators.
Common Mistakes
Confusing atto (10⁻¹⁸) with femto (10⁻¹⁵) — they differ by a factor of 1,000.
Educational Tips
Follow the prefix chain down: milli, micro, nano, pico, femto, atto — each step is 1,000× smaller.
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).
