## How to Convert Ounces to Metric Tonnes

*Example: How many metric tonnes are equivalent to 2.75 Ounces?*

As;

1 Ounces = 2.835E-5 metric tonnes

2.75 Ounces = Y metric tonnes

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

Y equals 2.75 times 2.835E-5 over 1

(i.e.) Y = 2.75 * 2.835E-5 / 1 = 7.79625E-5 metric tonnes

Answer is: 7.79625E-5 metric tonnes are equivalent to 2.75 Ounces.
