How much does my wood weigh?

Note: This chart shows the weight in either oz/foot for sticks, or oz/sq' for sheets. Often, wood is quoted in lbs/cubic foot. Please take this into consideration when comparing data from other charts.

1: The contest balsa was purchased from Superior Balsa, and is actually three sheets of 4" wide balsa.

2: I purchased three sheets of 1/8" Lite ply, 12"x48", on the same day. I weighed all three, and came up with the results shown. 

3: Balsa purchased from Superior Balsa. This was unspecified weight, and it came out pretty dense and strong.

4: I was surprised at the weight of the above sticks, so I hand picked some from Hobby Shack, and this is what I ended up with--about 2/3 the weight! Note that this wood disappeared from my box much faster than the heavier wood.rcfaq
