24 karat = 100% gold
Too soft for fine jewelry
22 karat = 91.7% gold
Too soft for fine jewelry
18 karat = 75.0% gold

Fair enough? (:
Standard 18K gold is a slightly different color than 14k gold due to its increase in purity. Both contain certain amounts of copper and silver which alter the gold color.
There is no difference apart from spelling. 18k is used in US, 18ct is used in the UK. It still means the same thing, they are the same purity of gold
Gold should be stamped with the appropriate karat level e.g. 9K=9 karat, 18k=18 karat. The higher the number the more gold the piece contains. The lowest tends to be 9K.
18k is not homgeneous
Well, 18k white gold it is alloys of different quality of precious metal that pass 18k acid test and magnet test ... Yellow gold alloys with Rhodium plated it is not white gold ... White gold its 18k+ white gold inside and white gold outside forever !
18k refers to the gold content (18k = 75% gold) with the rest being silver or other metals 159 refers to the purity of the silver
it is Russian or German standard of gold purity; which is about 76% of pure gold. Equal to 18K gold
The weight and purity are not related. A karat is a measure of purity when talking about gold, while a karat for a diamond is dependent on size so if the 10K and the 18K rings are approximately the same size, I would say that the 18K is heavier

Gold is sold by its purity (Karat) and its weight The Karat (K) is the purity of the gold: 24K Gold = 1000 = 100% Gold 18K Gold = 750 = 75% Gold 14K Gold = 585 = 58.5% Gold........and so on By knowing the weight of the gold and the purity (Karat) you can determine how much mass is solid 24K gold and determine a price!!
What does it mean if a silver colored bracelet has the letters pl 18k? Normally, a stamp of "18k" indicates the purity of gold in a piece of jewelry. I would think the bracelet is white gold, not silver.

To answer your question directly, 18k is not measured in carats.Your term '18k' is typically used to describe the purity of gold. In this case, 18k indicates that 18/24ths of the metal mix is gold, 24k, therefore, being pure gold. These karats are spelled karat.For a diamond, 18 carats indicates the weight of the diamond, one carat being equal to .20 grammes. These carats are spelled carat.
Karat numbers indicate the purity of the gold in a 24 point scale. 24 karats is pure gold, 18k is 18 parts out of 24, or 75% gold, and so on.
The abbreviation would be "1g Au" but it would not mean much without the purity (fine, 24K, 22K, 18K).
18K Gold: 18K Gold is 18/24ths, or three-quarters pure gold. Jewelry of this fineness is marked "18k" or "750," meaning 75 percent gold."
The crown is a standard mark, meaning the gold conforms to one of the gold standards. K stands for carat. It is a unit for purity of gold. 22K indicates that the ring is 91.7% gold and 8.3% other metals.
