What type of oak?
Rule of thumb mulipy the diameter in inches by 4.5.

 

[John Paul Sanborn]

The rule of thumb (ROT) I've heard is 1/4 - 1/3 inch average per year on urban trees. This gives a range.

Old growth hardwood have documentaition of 75-100 rings per inch. these being the best "tone wood" or for musical intruments.

Tells you why we have no Strativarias level makers these days.

The mesurment should be taken at 4.5 feet. (Daimeter at Brest Hight DBH)
