Under temperature, the SI base unit is the Kelvin (K), which is used to measure temperature in the International System of Units (SI).
Growing a tree helps the earth as it captures CO2 for a longer period
You can measure a tree with a few things. If I were you the easiest thing would be a ruler.
An ape tree would last longer if your talking about growing it.
because they dont have oxygen
The answer depends on the tree and what aspect of it you want to measure. There will obviously be different units for its mass and height. Even in linear measurements, you may wish to use different units for its height and girth.

Yes it could in till it reaches to it's high poltensional
You could stop the production of fruit by picking off all the blossoms. :)
Your question presumes that tree trunks are all circular. If you happen to find a circular tree trunk, you would measure around it to find the circumference. If the tree trunk is not circular, you will not be able to find the circumference but, you can measure around it to determine its perimeter.

The Yew. Taxus baccatta is a fairly slow growing tree.
The Royal Empress Tree.
Where is the tree growing?
What is the role of the mango tree growing in the backyard of Mendoza's house?
Your best bet here would be to use trigonometry. One stand a given distance away from the tree and sight the top of the tree, say with a clinometer, to measure the angle of elevation. Then knowing the angle and the distance you are from the tree, the height of the tree can be calculated with a tangent function.
Feet or metres would seem the most suitable.
