OK, some basic kiltmaking.

A fabric yard that kilt fabric is measured at is 60 inches wide and one yard or 36 inches long.
When making a kilt we cut the fabric in half lengthwise and join the two halves.

So, a kilt length is just the length of the piece used to make the kilt. If that length were 30 inches wide - 2 kilt yards would equal 1 fabric yard.

But kilts are almost never 30 inches in length from Selvedge up to the top of the top band. So we have to calculate how much fabric is in a kilt in square inches and compare that the the square inches in a fabric yard.

60X36=2160

Your kilt is 208X24=4992

4992/2160=2.31 fabric yards

If your kilt actually weighs 1.8 pounds then it is probably made from a 10 oz synthetic fabric
1.8/2.31=10.38
