## Step 6: Weight Empty Cylinders

Weight the empty cylinders.

I give you my result after I weighted about 24 tanks :

**Type #1 With plastic Base (Coleman Type)**

**Average empty weight : 384g**

This mean a 100% full tank will weight 849g (384g tare weight + 465g of propane)

**Type #2 With metal Base**

**Average empty weight : 417g**

This mean a 100% full tank will weight 882g (417g tare weight + 465g of propane)
