Gold Filled Markings (W1/20 14K G.F.) what it means: W=weight,

1/20 = 5% gold, G.F. = Gold Filled. Gold Filled is 300 times thicker than gold plating. Gold filled is bonded to brass or bronze with (fusing) heat and pressure. By law 5% of its total weight must be gold.

Gold Plating: Thin coating of gold over a base metal (Electroplating) A gold plated item will be marked 18K or 14K HGE (Heavy Gold Electroplating) Gold plating is 7 – 100 millionths of an inch thick.

Silver:

Sterling is 92.5% silver, 7.5% copper

Sterling Markings are .925, STER, STERLING.

Sterling from England are marked by a Lion Hallmark.

Silver Filled items are marked 1/20 silver filled.

Vermeil is sterling silver covered by an electroplating of gold.

Platinum:

Markings are PLAT, or PLATINUM, and maybe marked .900 or .950

Troy Pound (0.37kg) A mass unit is used to measure precious metals. There are 12 troy ounces in every troy pound. One troy pound is equal to 373 grams.

Troy Ounce The traditional unit of weight for precious metals and gems. 1 troy ounce = 480 grains 1 troy ounce = 24 scruples 1 troy ounce = 20 pennyweights (North American jewelery trade) 1 troy ounce = 1.097 ordinary ounce 1 troy ounce = 8 drams 1 troy ounce = 31.1034768 grams. 1 troy ounce = 120 carats 1 troy ounce = 155.52 metric carats (diamonds / precious stones). 3.75 troy ounces = 10 tolas (Indian sub-continent) 6.02 troy ounces = 5 taels (Hong Kong) 12 troy ounce=1 troy pound 14.583 troy ounce =16 avoirdupois ounce (1Pound) 32.15 troy ounces = 1 kilogramme (Kilo) 32,150 troy ounces = 1 metric ton (1,000 kilos) 1000 troy ounces = 31.1 kilograms Pennyweight (dwt): The pennyweight was the weight of a silver penny in medieval England. It is no coincidence that there were 240 pennies to the English pound. 240 silver pennies were equivalent to a pound of silver. The word sterling applies both to the English pound and to the standard purity of silver. 1 pennyweight = 24 grains (dwt) (1 old time French penny) 1.55 grams=1 pennyweight (dwt) 20 dwt=1 troy ounce 240 pennyweights = 1 pound troy 24 grains=1 dwt 1 pennyweight =.05 troy ounce 1 gram=.643 pennyweight Gram 1 gram =.03215 troy ounce 1 gram =.643 pennyweight 1.555 grams = 1 pennyweight (dwt) 1 gram =0.00267923 apothecary or troy pound 1 gram =0.00220462 avoirdupois pound 1 gram =0.0321507 apothecary or troy ounce 1 gram =0.564383 avoirdupois dram 1 gram =0.257206 apothecary or troy dram 1 gram =0.6430149 pennyweight 1 gram =0.771618 scruple 1 gram =15.4324 grains 1 gram =1×10^-6 metric ton 1 gram =1×10^-4 myriagram 1 gram =0.001 kilogram 1 gram =5 metric carats 1 gram =1000 milligrams 1 gram =1×10^6 microgram 1 Gram = 5 Carats Gram-Calorie (mean) Gram-Calorie (mean) =1.5593×10^-6 horse power hours Gram-Calorie (mean) =0.001 kilogram calorie Gram-Calorie (mean) = 0.0011628 watt-hour Gram-Calorie (mean) =0.001459 cubic foot atmosphere Gram-Calorie (mean) =0.0039685 BTU (mean) Gram-Calorie (mean) =0.0039685 BTU (mean) Gram-Calorie (mean) =0.041311 liter-atmosphere Gram-Calorie (mean) =0.42685 kilogram-meter Gram-Calorie (mean) =3.0874 foot-pounds Gram-Calorie (mean) =4.186 joules (absolute) Gram-Calorie (mean) =99.334 foot-poundals Gram-calorie (15°C) = 4.185 joules (absolute).

Grain: An ancient unit which was originally based on the weight of a grain of wheat. The grain is the smallest unit of weight in the avoirdupois, troy, and apothecaries systems. Surprisingly it is identical in all three systems. 1 grain = 64.8 milligrams 1 grain = 0.0648 grams 4 grains = 1 carat 15.432 grains = 1 gram 20 grains = 1 scruple 24 grains =1 pennyweight 480 grains = 1 troy ounce 5760 grains = 1 troy pound 437.5 grains = 1 ounce avoirdupois 7000 grains = 1 pound avoirdupois Grain = 1/7000 avoirdupois pound Grain = 1/5760 apothecary or troy pound Grain = 0.0022857 avoirdupois ounce Grain = 0.0020833 apothecary or troy ounce Grain = 0.03657143 avoirdupois dram Grain = 0.016667 apothecary or troy dram Grain = 0.0416667 troy pennyweight Grain = 0.05000 apothecary scruple Grain =0.064798918 gram Grain =0.3240 metric carat Grain =64.798918 milligram

Dram or Drachm An ancient unit of weight, also a Greek coin. It is believed to have originally meant the amount which one could hold in one’s hand. 16 drams = 1 ounce avoirdupois 8 drams = 1 ounce apothecaries 1 drams = 27.34375 grains 1 dram = 1.772 grams 3 scruples = 1 drachm 20 grains = 1 scruple

Momme A unit of weight previously used in Japan to weigh pearls. 75 grains = momme 18.75 carats = 1 momme 3.75 grams = 1 momme Imperial System A British system developed and refined from the earlier Roman systems used in Britain during the middle ages. Kevin Loughrey from Non Volatile Technologies Pty Ltd contributed some corrections below. 20 cwt = 1 ton (40 bushells or 160 stones) = 1 ton avoirdupois 4 stones = 1 bushell (56lbs) 1 hundredweight (cwt) = 112lbs (2 bushells, or 8 stones) 14 pounds avoirdupois = 1 stone avoirdupois 16 ounces avoirdupois = 1 pound avoirdupois 1 ounce avoirdupois = 28.349523 grams approx. 1 pound avoirdupois = 453.59237 grams 1 ton avoirdupois = 2240 pounds avoirdupois

MORE USEFUL CONVERSIONS Take the decimal fraction of feet and divide by 0.08333 (1/12th) and this will give you inches and decimals of an inch. For example – 6.37 feet. Take the 0.37 feet and divide by 0.0833 = 4.44 inches . So for 6.37 ft. we can also say 6 ft. – 4.44 in. Now take the 0.44 in. and round it down to 0.4 which is 4/10″ We can now say 6.37′ approximately equals 6′ – 4 4/10″ For fractions of an inch other than tenth’s, take the decimal remainder of inches and divide by: 0.125 for the number of eighth’s 0.0625 for the number of sixteenth’s 0.03125 for the number of thirty-second’s 0.015625 for the number of sixty-fourth’s, and so on. For example – 4.382 inches. For eighth’s, divide the remainder, 0.382 by 0.125 and the answer is 3.056 so the fraction is a bit over 3 eighth’s, therefore the answer ends up as approx. 4 3/8″
