Formula for estimating Gold Bar WEIGHT & KARET PERCENTAGE1 kg = 32.15 Troy oz.

Conversions : 1 oz = 28.35 grams 1 lb = 16 oz 1 kg = 2.2 lbs (35.2 oz.)1 Troy oz = 31.1035 gr. 1 lb = 0.4536 kg 1,000 kg = 1 Ton (long)

Formula for estimating Gold Bar WEIGHT

First : Measure Bar Length, Width and Height. Note: if bar LENGTH (L) and WIDTH (W) dimensions are different, than follow example drawing below by first adding the two Widths (W1 + W2) and then dividing this total by 2 to get exact WIDTH. Then use thesame formula to get the exact LENGTH total (L1 + L2 divided by 2 = correct LENGTH).

GOLD BAR 15% .624(Side View) 14% .583

Second : Multiply Bar LENGTH X WIDTH X HEIGHTThird : Multiply ABOVE answer by 19.3 (Specific Gravity of Gold)

For PLATINUM, multiply by 21.45 (Specific Gravity of Platinum)

EXAMPLE

40.64cm (16") X 10.16cm (4") X 10.16cm (4") = 4,195.0883 cubic cm4,195.0883cm X 19.3 = 80,965.204 grams = 80.965 kilograms

Formula for estimating Gold Bar KARAT Percentage

If dimensions of : 40.64 Length, 10.16 Height & 10.16 Width = 80.965 kilograms at 24 Karats, then24 divided by 80.965 Kg = .2964243

So, multiply the actual Kg weight of the Gold Bar X .2964243

EXAMPLE

Your Gold Bar has exact dimensions as above sample but actual weight is only 78 Kg. Then, 78.0 Kg X .2964243 = 23.121095 Karats (This is the approx. Karat % of your Gold Bar).

Multiply L.M.E. Gold Price per ounce X Ounces X (See Conversion Chart)

See Examples Below (Gold Price of US$300 per ounce & One Kg = 32.15 Troy ounces)

1) US$300 X 32.15 oz. X 1 (24K) = US$9,645.00 per KG.2) US$300 X 32.15 oz. X .957 (23K) = US$9,230.265 per KG.3) US$300 X 32.15 oz. X .916 (22K) = US$8,834.82 per KG.4) US$300 X 32.15 oz. X .874 (21K) = US$8,429.73 per KG.
