Knitting Stockinette in the Round vs. Flat

I've always wondered what the difference would be between knitting stockinette in the round and knitting it flat. Since my purls are a little bigger, I've assumed that my Flat gauge would be a little looser than my in-the-round gauge. I've never really had the energy to take a look. Luckily, my Stitches 2015 class homework has me knitting stockinette in the round for one class and stockinette flat for another. So I'm taking this as an opportunity to compare my gauge. I am knitting these swatches using Cascade 220 on US 6 (4.0mm) needles.

Swatch in the round: Cast on 72 stitches using long-tailed cast on. Knit until swatch reaches 4.5 inches. Bind off using K2tog tbl bind off. Block by laying out to dry -- no stretching, just shaping.

Flat Swatch: Cast on 42 using long-tailed cast on. Knit until swatch reaches 7 inches. Since I was on a WS row, I used the P2tog bind off. Block by laying out to dry, no stretching.

24 stitches / 4 inches, 33 rows / 4" 22.5 stitches / 4", 31 rows / 4"
23.5 stitches/ 4 inches, 30 rows / 4 inches 21.5 stitches / 4"; 30.5 rows / 4"

As you can see I have a whole stitch difference between my flat stockinette gauge and my in the round stockinette gauge. How does this affect a project? Lets assume I have knit a flat swatch but intend to knit a sweater in the round. Lets assume as well that the circumference I will be knitting is 36". So looking at my flat swatch I will need to cast on 21.5 stitches * 9 or 193.5 stitches. I would round that up to 194 stitches. Now I knit for a while only to discover that my circumference is *not* 36 inches because my in the round gauge is 22.5 stitches / 4" or 5.625 stitches / inch. My actual circumference would be 194 / 5.625 = 34.488 or 34 1/2". I've lost a whole 1 1/2" from the sweater, which would definitely affect fit.

So what's the lesson? When knitting in the round, make sure your swatch is knit in the round as well.
