Metric Units

We use the metric system because in life evrything is envolved by measurements. We measure water.. Gallons,Ounces etc , meaure weight pounds /kilo. 

The neighborhood i live in, has 3 examples of metric units. 

1.when we cook we have to use a certain amount of butter so itll say we have to use 2 ounces. 

2.when we go down the street its 5 yards,when they remade the ground cement they had to meausure the ground to make sure they didn't pass the amount that it was suppose to be.

3.a way we also use metric units at my house when we meausure the bed, we have to see if its width & length .. So if for us to know we would meausre in inches
