snugglekittyI just got a new coat. It is sixty/forty alpaca/wool.
My old coat is 100% wool. The coats are the same thickness.
Given the truism (which may or may not be correct - wikipedia doesn't seem to know) that alpaca is five times warmer than wool, and discounting other factors, how much warmer than my old coat is my new coat?
I came up with 3.4 times as warm, but I'm not positive I'm right.
Note: this is not made up. I actually do have a new coat as described above. It is much lighter than my older coat but seems quite toasty.
