25.4 mm would be 100,000 gauge so
24 x 100000/25.4 = 94488 gauge

Is 20 gauge the same as 20 mil? Someone said they are the same, but I was sure mil was thicker than gauge. Any ideas?

1 mil seems to be 100 gauge, but, really, there is no formal definition. Anyone can make up a different definition of gauge. Just ask for real thickness

In terms of PVC, the specs on a Sea-Doo inflatable toy tell me it's made of 30 gauge PVC, while the specs on a PVC pond liner at Home Depot describe it as 20 mil. Both seem very close in thickness. Applying that 100:1 ratio would make the 20 mil pond liner 2000 gauge. Doesn't seem right....

This is a conversion chart. Copy/paste the link.

Please note that is only for wire. "Gauge" has numerous definitions applying to different situations and materials. From the "gauge" article at the same site:
Quote:
gauge (ga) [1]
a traditional unit measuring the interior diameter of a shotgun barrel. The gauge of a shotgun was the number of lead balls, each of a size just fitting inside the barrel, that were required to make up a pound. In other words, if a lead ball weighing 1/12 pound just fit in the barrel of a shotgun, then it was a 12-gauge shotgun. Today, the internal diameters for each gauge number are read from a table.
gauge (ga) [2]
a unit expressing the fineness of a knitted fabric, equal to the number of loops per 1.5 inches (38.1 millimeters). The same unit is also used to express the size of the knitting needles used to create a fabric of that fineness.
gauge (ga) [3]
a traditional unit measuring the diameter (or the cross-sectional area) of a wire. Various wire gauge scales have been used in the U.S. and Britain. In traditional scales, larger gauge numbers represent thinner wires. (For very thick wires, repeated zeros are used instead of negative numbers, so gauges 00, 000, and 0000 represent -1, -2, and -3, respectively.) In the American Wire Gauge (AWG) scale, 0000 gauge represents a wire having a diameter of 0.46 inch and 36 gauge represents a diameter of 0.005 inch (5 mils). Diameters for the other gauges are obtained by geometric interpolation, meaning that the ratio between successive diameters is a constant, except for necessary roundoff. Thus n gauge wire has a diameter of .00592((36-n)/39) inch. The metric wire gauge number is equal to 10 times the diameter of the wire, in millimeters; thus a metric 8 gauge wire has diameter 0.8 millimeters. A table of wire gauge equivalents is provided.
gauge (ga) [4]
a traditional unit measuring the thickness of sheet metal. Larger gauge numbers represent thinner metal: 10 gauge represents a thickness of 0.1345 inch (3.416 millimeters) and each increase of 1 in the gauge number corresponds to a reduction of about 10% in the thickness. A table is provided.
gauge (ga) [5]
a traditional unit measuring the thickness of plastic film. For this purpose 1 gauge equals 0.01 mil [1] or 10-5 inch (0.254 micrometer).
gauge (ga) [6]
a traditional unit measuring the thickness of tennis racquet strings. There are two systems in use. In the U.S. system larger gauge numbers indicate thinner strings; in the European system larger gauge numbers indicate thicker strings. A table is provided.

I would say the real problem is what is "gauge" and how do you convert it to any "real" unit.
*Millimeters are millimeters, simple and straightforward, worldwide
*Inches are 25.4 mm (that's their legal definition in the US)
*"Gauge" is poorly defined. Since it means many things to many people, it doesn't mean anything (consistent).

Lightbulb Plastic Thickness Conversion Chart!! (attempt)

Okay, i myself have gone mad over this whole conversion issue and can't find a chart anywhere! therefore i've decided to read this entire posting thread & piece together some knowledge & came up w/ the below table. can some pro or experts out there verify it??

.................................................. TO THIS (do the actions below)
TO CONVERT FROM below|....Gauge....|....... mil......|....Inch......|.....mm.......|...microns
...Gauge.......................|........-.......|....../100.....|../100000...|..*0.00025...|..*0.245
...Mil............................|.....*100.....| ......-.........|.../1000.....|./39.370079..|..*24.5
...Inch..........................|..*100000...|... ..*1000....|.......-.......|.....*25.4.....|..*24500
...mm...........................|../0.00025...|.*39.370079.|..../25.4....|........-........|..*1000
...microns (um or mym)....|..../0.245....|....../24.5....|.../24500...|...../1000.....|......-

For example:
what is 30 gauge in mm? do this: 30 gauge*0.00025 = 0.0075mm
what is .35 mil in inches? do this: 35 mil/1000 = 0.035 inch
what is 2.0 mm in gauge? do this: 2 mm*100 = 200 gauge

can someone test it out & let me know what you think?

Lightbulb Plastic Thickness Conversion Chart!! (attempt)

I posted the same content earlier but didn't create a user ID so that i can track your replies. in an attempt to sort this whole conversion effort our, can someone let me know if the conversion table i created is accurate? thanks!

........................................To This (do the below).................................
From This (below).......|Gauge....|mil............|Inch..... |mm..........|microns
....Gauge...................|............|/100.........|/100000|*0.00025...|*0.245
....mil .......................|*100......|............... |/1000...|/39.370079|*24.5
....Inch.....................|*100000.|*1000...... ..|..........|*25.4........|*24500
....mm.......................|/0.00025.|*39.370079|/25.4...|...............|*1000
....microns (um or mym)|/0.245....|/24.5........|/24500.|/1000........|........
