1 inch=2.54 cm
1 yd=36 inches=0.9144 m=91.44 cm

There is an easy way to convert gsm to oz/yd2.
Divide the gsm by 33.906 - really that is all.
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
1 yard=0.9144 meters
1 yard squared=0.9144 m x 0.9144 m=0.83612736 meters squared

Therefore

1 oz/yd2=28.3495231g/.83612736 m2=33.90574744 g/m2
Rounded up to three decimal places it is 33.906
