Learn Apparel Merchandising, Learn Fashion design.
Find out the calculations of Yards from kgs: (in knit fabric)

Say,
       Fabric GSM   - 140
       Fabric width   -  45"
       Fabric Weight -  0.49181 kg

Rules:

Fabric length  =  Fabric weight / ( Fab width X Fab GSM /1550 / 1000)

Fabric length  =  0.49181 / ( 6300 / 1550 / 1000)

Fabric length  =  0.49181 / 0.00406451612

Fabric length  = 121" (where the fab width is 45" open)

Farbic length  = 3.3611 yards    (121/36")
