thickness measurements?

#1

Post by JETTYWOLF »

Can someone (I know your out there) post a quick reference chart of:

Gauge = millimeters = inches, so at a quick glance when
comparing boat alloy thickness' I can see what those numbers
really mean.

I guess, since "BLM" uses inches, IE: 3/16th's inches and 1/4 inch etc.
I'm used to reading that.

But I look on some manufactures sites and see 0.190" or 10 gauge for instance...

Is it just me that's match or measurement handicapped?

If so just say it...I can take it. I have thick skin.

Thanks.

Hey Capt. Dave,

4mm=5/32 (.157)
5mm=.196 or a heavy 3/16 (.187)
6mm=.236 shy of 1/4" (.250)
7mm=.275 heavy 1/4" (.250)
8mm=.315 or 5/16" (.312)
10mm=.394 or heavy 3/8" (.375)

The multiplier for MM to Inches is 25.4 so the american decimal times 25.4 to get MM or the MM divided by 25.4 to get the decimal (inches)


Not sure on sheet metal gauge thickness but I believe gauge is a range from .XXX to .YYY (example)

Thanks Alloy...The list does me good. What's the .000 for 1/4 inch?

I guess I could do the M-A-T-H!

Ya know I'm always comparing against "our" boats, because I'm looking at the thickness' of small heavy duty tiller style boats and Jonboats even.

Still would like to have me a lil creek boat....

I even for a second considered one of these:

tow it behind my boat at 30 knots, pull up into a creek and get in it and hunt "tailing Redfish"...but that, like I said only lasted a second.

1/8=.125
5/32=.156
3/16=.187
1/4-.250
5/16=.312
3/8=.375
7/16-.437
1/2"=.500
9/16=.562
5/8=.625
11/16-.687
3/4=.750
13/16=.812
7/8=.875
15/16-.937
1"=1.00

to get the decimal equivalent for a fraction take the first number of the fraction and divide by the second number of the fraction

example 1/4"............1 divided by 4=.25

Jetty,
sheet goods and roll goods are usually sold in thousands of an inch ie. (.0025).
plate or bar and rod are in inches ie.( 3/4 " or 2"x2" or 1 1/4 " )
goods with thickness less than 1/8 " are usualy tendered to the trades and most commonly by Gauge standards.
