Diameter/circumference

[dun]

My math skills are pretty rusty. How do you arrive at diameter from circumfreence. A circumference of 188 inches would be what diameter.

Thanks

59.84

C/d=PI

I thought they were the same thing. Never was good in math. I bet Pi has something to do with it

Diameter = circumference divided by pi (3.1417)

Therefore a circle with a circumference of 188 would have a diameter of 59.840213

Exact same answer I get.

I used a reverse route and wound up in the same formula you did.

Thanks. The state record Sassafras tree has a circumference of 188 inches. This morning down along the creek bottom I found on that has a diameter of 38 inches. I was just curious if it was even close to the record. On one of the farms we used to have we had a chinkipin that was 2 inches greater in circ. then the state record. The top had been struck by lightning and all that was left was about the lower 30 foot. Missed the record by 5 feet.
When I see these great old trees I marvel at the size and am alwasy curious how big others of the same type may be.
Sorry, just babbling again

Don't stop "babbling". Heck I was enjoying it.

A 60in. Sassafras? That's incredible. I don't know that I've ever seen one over 12in. here. I'm fascinated by giant trees also. I have the whole list of Ga. state records over at the farm. I'll check Ga.'s Sassafras record when I go over there later. I saw the state record Magnolia back in the 70's over near Tifton when I was in school at ABAC. Unforgettably awesome. It stood alone in a 200 ac. peanut field, the tree being surrounded by an ancient wrought iron fence. Went to see it quite a few times actually. I liked to take visitors to see it. It has since died. Probably lightening struck.

sorry did you mean 60ft???.......I saw the allegedly Oldest Magnolia tree in America, when I was in Mississippi in May in Nanches, in one of the old cotton plantations it had a fence around it and a plaque stating it was planted by the original owners Daughter. and was known to be the oldest surviving in America.

 

[llcupit]

Ok chrisy Natchez or Nanches. Just wondering.

Our houase sits on top of a fairly decent hill. One of the things that sold us on it was a clear view of a grove of native pecan trees that are huge. They are about a quarter mile to the west. Now the people who own the palce between us and the trees are building a new house half the size of Dallas right between us. Z

 

[ga. prime]

chrissy, no I meant 60 in. diameter breast height(DBH). DBH, tree height, and limb spread are used to determine champion trees in th U.S. And you meant Natchez, not Nanches. That is the home of the U.S. champion Magnolia.

yes I know I spelt it wrong I couldn't remember, so I spelt it how it sounded, thanks for the correction. sorry I thought you meant height, meaning from ground to top of tree. as 60in is not very high. my mistake

Dun,

Ga. Prime mentioned about DBB. Most records with girth of trees follow this instead of the base of the tree near the ground. There is also a formula to estimate how many board feet of lumber one can expect to yield from a tree.

Anytime I refer to diameter it's DBH. About the only time that isn;t the diameter I'm ocncerned with is when I've determining the width of the hinge and notch depth for felling.
A forster frind of mine gave me a nifty yard stick kind of deal. When you stand next to a tree and extend this "stick" horizontally at arms length it shows the DBH. Pretty slick deal. It would probably work for any height you held it at, but since DBH is the standard I don;t think I'll get down on my knees and try it to see if it will work.

I'd like to have that stick to measure some of the live oak trees around here. We have some HUGE live oaks around here. Most of the big ones were planted back in the plantation days.

 

[mtncows]

Dun, what you have is a Biltmore stick.WE used them in the foretry part of Ag class in high school back in the 70's when wheels were square and we walked in a foot of snow to school.

Its called a Biltmore Stick. Can determine height as well

For my purposes I don;t really care about the height in feet. I just use an axe handle and use it to determine where the top of the tree will be when I fell it.
