The chart below shows the air dried density of common wood species - this is the number given in the first column after the wood name.
This indicates the approx weight of one cubic foot of the wood when air-dried (about 20% moisture).
For the purposes of the

Burn Time Calculator on this site, we have used the following densities for our calculations:
25 - Soft
30 - Medium
38 - Hard
44 - Extra Hard
