An appropriate unit to measure the height of an oak tree is generally feet or meters. To measure the height of a tree, you can use different methods depending on the available resources and your level of accuracy required.

1. Method 1: Stick and Tape Measure
- Find a straight stick that is longer than the estimated height of the tree.
- Hold the stick vertically, with one end touching the ground, and make sure it is straight.
- Move back from the tree until you can see the top of the tree align with the top of the stick.
- Measure the distance between you and the tree using a tape measure. This distance is the approximate height of the tree.

2. Method 2: Clinometer
- A clinometer is a device used to measure the angle between the ground and the top of the tree.
- Stand at a predetermined distance from the tree, which could be measured using a tape measure.
- Look up through the clinometer and align the crosshair with the top of the tree.
- Read the angle measurement shown on the clinometer.
- By using trigonometry, you can calculate the height of the tree using the distance from the tree and the angle measured.

3. Method 3: Laser Rangefinder
- Use a laser rangefinder, which emits a laser beam that bounces back when it hits an object, to measure the distance from you to the top of the tree.
- Aim the laser rangefinder at the top of the tree and press the button to calculate the distance.
- The laser rangefinder will display the distance, which is the approximate height of the tree.

Remember, these methods provide an approximation of the tree's height, as they rely on several assumptions and measurements. For accurate measurements, it may be necessary to use professional equipment or seek assistance from an arborist or forestry expert.
