1. ## Needles?

Can anyone please help convert the numbers? Over here we talk in millimeters. I usually use 0.8millimeter*40millimeter needles. You guys are talking about 20-21-22-23 gauge... I think I got as far as that the smaller the number the thicker the needle, Am I right??

2. ## Gauge Conversion

Okay, campers, class is now in session . . .

You've got the right picture, Swedeboy. The first number is the gauge, and the second number is the length of the needle.

Let's briefly address length: 1 mm = 0.04 inches. Therefore, the example you used of a 0.8*40 mm needle means that the needle's length is 1.6 inches (or 40*0.04 - for Americans, that's 40x0.04). That would be similar to the 1-1/2" long needles we use in the U.S. and Canada.

As far as gauge, you're correct: The smaller the gauge, the thicker the needle. Here is the basic conversion chart for the most common needles used to inject AS:

Corrected Conversion Chart

18 gauge = 1.2446 mm
19 gauge = 1.0688 mm
20 gauge = 0.8890 mm
21 gauge = 0.8128 mm
22 gauge = 0.7112 mm
23 gauge = 0.6350 mm
24 gauge = 0.5588 mm
25 gauge = 0.5080 mm
26 gauge = 0.4572 mm
27 gauge = 0.4064 mm

Thus, in the U.S. and Canada, we generally use 18-20 gauge needles to draw oil-based solutions and 22-23 gauge needles to inject them, and we use 25 gauge needles to draw and inject water-based solutions except for insulin , for which higher gauge (smaller) needles are used. In terms of length, for glute injections we use 80 mm needles (1-1/2 inches here), and for delt and quad injections we use 25 mm needles (1 inch).

(Thank you, thank you . . . I knew liberal arts would pay off some day.)

3. THANX TNT!
So you guys use 22-23 gouge to inject (oil). According to the convertion I only got one thing to say. You guys are really . As I said I use 0.8millimeter and that's not on the list, if it was it should be someting like a 30gauge. Are you whales or am I a Pu--y? (girls, please forgive me for the badly chosen word. Don't want to offend anybody)

4. TNT I don't think that your Gauge to mm. conversions are correct.
I lived in Europe for 14 years and I know the metric system perfectly. I know the Gauge system pretty good too. I don't know the exact conversion, but yours looks way off.
Looking at your conversion for 18 gauge= 3.7338 mm, DAMN MAN
do you know how big that is. That's too big for a horse LOL
Swedeboy keep looking, if I find conversions I will post them.

5. Heres what I found on the net. TNT, you got me pretty worried there for a while.

gauge inches millimeters
10- .1350- 3.4290
11- .1205- 3.0607
12- .1055- 2.6797
13- .0915- 2.3241
14- .0800- 2.0320
15- .0720- 1.8288
16- .0625- 1.5875
17- .0540- 1.3716
18- .0475- 1.2065
19- .0410- 1.0414
20- .0348- .8839
21- .0317- .8052
22- .0286- .7264
23- .0258- .6553
24- .0230- .5842
25- .0204- .5182
26- .0181- .4597
27- .0173- .4394
28- .0162- .4115
29- .0150- .3810
30- .0140- .3556

Since I use 0.8millimeter which is about a 21 gauge according to this, and you guys use 22 or 23 gauges I guess I'm the whale and you....

Genuine and Swedeboy, you guys are absolutely correct - a major gaffe on my part.

I used a chart titled Stub's Needle Gauge Sizes which is used in diagnostic radiology, and includes conversions from gauges to inches, millimeters, and size (an esoteric method rarely used). Unfortunately, I copied the wrong column - sizes instead of gauge-to-mm conversions.

I've changed my original post to reflect the correct numbers, and stand humbled before you all. The chart, which is U.S. based, is much closer to Swedeboy's correct numbers. Ah, well, so much for my perfect image . . . I can now return to being a dumb weight jock.

7. We all make mistakes TNT. (But hopefully we learn from them .I'm trully glad I didn't try to use a needle according to your first conversiontable. I'd be walking around with a big hole in my gluteus )

8. But just think of how quick you would have been able to inject!! I use needles at work and they have metric sizing and the imperial sizes on the pkging

9. TNT - Whether your right or wrong, your posts are a top quality. You must have voice recognition on your PC to type so damn fast!

As Far as I'm concerned, you are the still most well rounded 'poster' that we so luckily have. Bro, I make mistakes daily.....hell, HOURLY! So, don't make me feel like a c0ckhead when you say you're "dumb" after making one mistake. I've been ''dumb'' dozens of times. What does that make me?

11. Don't worry TNT it's a small mistake. We all make them and we make big ones too. All your posts are great Man so don't let it bother you. We still belive in you

12. 1 inch equals 2.54cm. 40mm's equals 4cm's. 4cm's equals 1.58 inches.
