How much is a square worth?

While idly chatting with Dear Hubby tonight, I began to wonder how much a 2.5 inch square costs.
In round numbers, consider a meter of fabric to be 1x1 meters, and a meter of fabric to cost Eur 20, then you get 10000 square centimeters per meter of fabric, or Eur 0.002 per square centimeter.
A 2.5 inch square is roughly 6.35 cm on a side, or about 40 square centimeters per 2.5 inch square, which corresponds to roughly 8 Euro cents per square.
Yes, this is how I spend my evenings sometimes.
