Some examples

To convert oz/sq yard to total fabric weight use the following formula

  • Weight per linear yard = fabric width / 36 * Weight /sq yard  * Total length of fabric in yards
    (As an example, let's calculate the weight of 7 yards of Harbor-Time.  Harbor Time is 62" wide so the weight of 7 yards is 62 / 36 * 11 * 7 =  132.6 oz, or 8.3 lbs.)

To convert oz/sq yard to g/sq m use the following formula

  • Weight, oz per sq yd * 33.906 = Weight, grams per square meter
    (As an example, let's convert the weight of Harbor-Time, whose English weight is 11 oz/sq yd.  11* 33.906 = 373 g/sq m)

To convert mils to mm use the following formula

  • Thickness in mils x 0.0254 = Thickness in millimeters
    (As an example, let's calculate the thickness of Harbor-Time, which is 16 mils (0.016") thick. 16 * 0.0254 = 0.41mm)
