To determine gsm from oz/yd2 you do the reverse - multiple by 33.906.
If it helps, this is what the formulas are based upon:
- 1 oz = 28.3495231 grams (oz to grams converter)
- 1 yard = 0.9144 meters (yards to meters converter)
- 1 yard squared = 0.9144 m x 0.9144 m = 0.83612736 meters squared (convert square meters to square yards)
Therefore
- 1 oz/yd² = 28.3495231g/.83612736 m² = 33.90574744 g/m2
- Rounded up to three decimal places it is 33.906
