On a watch case, plaque OR G 20 microns means that the case is solid gold. The 20 micron relates to the thickness of the gold plating.
20 microns is 0.002cm
This is the thickness of the gold plating on the lighter. 20u would be 20 microns
100 microns is 20 times thicker than 5 microns
Above 5 microns, up to 30 microns
1 mm = 1000 microns so 0.02 mm = 0.02*1000 = 20 microns. Simple!
1 mm = 1000 microns. 20/1000=.02mm
about nothing. 24k HGE, means 24 karat gold (.999pure) heavy gold electroplate. which means over 5 microns (which is sometimes called flash plating) so more than five microns up to about 15 or 20 microns i'd guess. so the ammount of gold on your item would be in the microgram scale, almost nothing by weight or value.
20 microns means 20 millionths of a meter or about 1/1300-inch. For jewelry it refers to the thickness of the gold plating (usually) on silver base metal. The thicker it is the higher the cost, but the more durable it is also.
Marking on jewelry, watch cases, or pens. Plaque is plating, lamine is mechanically applied, such as American "Gold Filled" and 20 microns is thickness of precious metal, fondacier inox means base metal is stainless steel. For example, plaque OR G 20 fondacier inox would mean a 20 micron plating of gold (French word is OR) on stainless steel.
