About Carat (ct)
Definition
The carat is a unit of mass used for gemstones and pearls, equal to exactly 200 milligrams (0.2 grams).
Mathematical Relationship
1 ct = 0.2 g = 200 mg = 0.007055 oz.
Conversion Formula
To convert carats to grams: multiply by 0.2. To convert grams to carats: multiply by 5.
Practical Applications
Diamond grading and pricing, gemstone trade, pearl classification, and jewelry appraisal.
Interesting Facts

Common Mistakes
Confusing carat (ct, mass) with karat (K, gold purity). 24K gold is pure gold; a 24-carat diamond weighs 4.8 g.
Educational Tips
Carat = weight of a gem. Karat = purity of gold. They sound the same but measure completely different things.
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).
