Needle Gauges

Posted by Laura on February 2, 2010

I was wondering about the relationship of needles and gauge sizes. This is what I found out:

The first hollow needed used for injection of was made of silver measuring 3cm long and 5mm in diameter  and had a screw used as the plunger. It was made in 1844 by Établissements Charrière and invented by Francis Rynd.

The inverse of gauge sizes to diameter is from the original use of drawing metal through a wire-drawing plate. The original size is One. After passing though the different sizes on the plate, you could make sixteen16-gauge wires from the original one. Or ten 10-gauge wires from the original one. Or two 2-gauge wires from the original one – see where this is going? +come+from+the+drawing+plates&source=bl&ots=Zntoq0KXKe&sig= 45DCzIZmgTBiJNJHIyiChqSNTIo&hl=en&ei=VJpoS_ugJYOSsgPth7GbBQ&sa =X&oi=book_result&ct=result&resnum=7&ved=0CCMQ6AEwBg#v=onepage&q=&f=false
