# Knitting Questions

Hi.I was wondering what does pi mean?

Also what does circumference ,diameter and height mean like for a hat for example?
What does they mean when they say a multiple of 5 + 2" .?
Any help would be nice.
Thanks.

Is it relation to gauge? It might be âper inch.â Usually itâs SPI which is stitches per inch.

Circumference is how big around the hat is. The average hat is probably 20-22". If youâre making up your own pattern measure the head and do a swatch to figure out your stitches per inch over 4 inches.

The 2 makes the pattern design work. So to calculate your cast on youâd only that the +2 once. Because itâs a multiple of 5 the cast on would be 5, 10, 15 etc and then add 2.

Hi Jan.How does the 2 make the design work does a person have to use it?does the 2 mean 2 sts?What does a multiple of 5 mean?What does multiple of numbers mean?

If youâre doing K2P2 on a flat piece it will be multiples of 4+2 so it will start with a K2 and end with a K2.

You donât have to do anything but you can figure thereâs a reason something is written as it is. You should know why youâre changing something before changing it.
For instance if you are changing a K2P2 flat piece to round you would leave off the +2 so it will flow into the beginning of the next round.

I donât remember how I changed it but I had a continual cable panel that I changed to knit in the round so it is continual all around the sweater. I may have just taken off the +X or I may have cut some of the multiple to get where both sides would match up to each other. Then I used that multiple to come close to my sweater size. Then adjusted needle size to fine tune it.

Multiple is a math term. 12 is a multiple of 4, 4 multiplied 3 times is 12.

As Mike said whether you add the +2 or not depends on the method of knitting and the pattern. If the pattern or stitch says to do that I wouldnât change it unless you are also changing the method (IE from flat to in the round). If youâre a new knitter I suggest you stick to both the knitting method and pattern suggestions till you know what yourâe doing so youâll have less errors and frogging.

Also as Mike said multiples is a math term. A multiple of 5 is 5, 10, 15, 20 etc. A multiple of 7 is 7, 14, 21, etc.
