I'm quite confused shopping for fashion materials on aliexpress. I'm familiar with per yard or meters measurements, for example, 1 yard by 100 means the portion is 36 inches wide and 100 inches long. On aliexpress though, they're like:
Size: 54x145cm
and
Buy 1pcs=1pcs 50/100cm*145cm

Buy 2pcs=1pcs 100/200cm*145cm

Buy 3pcs=1pcs 150/300cm*145cm
etc.

Can someone educate me on how to translate the above to simple yards/inches that I'm familiar with? What is 50/100cm*145cm? Nawa o.
