## How to Convert Ounces to Grams

*Example: How many grams are equivalent to 27.89 Ounces?*

As;

1 Ounces = 28.35 grams

27.89 Ounces = Y grams

Assuming Y is the answer, and by criss-cross principle;

Y equals 27.89 times 28.35 over 1

(i.e.) Y = 27.89 * 28.35 / 1 = 790.6815 grams

Answer is: 790.6815 grams are equivalent to 27.89 Ounces.
