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.

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
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.
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.
To convert 20 microns to millimeters, divide by 1000: 20 microns = 20/1000 = 0.02 mm Then, divide 0.02 mm by 20 mm: 0.02 mm / 20 mm = 0.001
2c microns on jewelry refers to the thickness of the gold plating on the piece. In this case, the gold plating is 2 microns thick, indicating a higher quality and longer-lasting finish compared to thinner plating.
The thickness of gold on a gold-filled watch varies, including on the same watch, as a gold-filled finish can vary in thickness. But generally, a gold-filled finish will be about 20-40 microns thick. A 20 micron gold-plate finish is a bit thinner than most filled-gold finishes but is more uniform. A 20 micron gold-plate finish will wear a long time and compares well with a gold-filled finish.
