How to measure the height of the Christmas tree on Christmas tree market
When selling real Christmas trees in the Internet shop, and at Christmas markets we measure the height of the tree from the butt cut to the end of last branches. The length of the head when measuring the height take into account.
As measuring instrument we use only certified levelling rods that allow you to find the exact height of the tree even in the dark.
How to measure the height of the tree in nature
The first method
You will need a tape measure or other device for measuring length, a sufficiently powerful light source (sun or lamp), and of the tree itself. It will be necessary to measure the length of shadows that cast you and spruce. Knowing your height, by simple calculations you can easily determine the height of the tree.
- Take a situation in which both the shade and ate, falling on the horizontal surface. Measure the length of his own shadow. For this you will need either an assistant, or will have to combine the shadow from his head with some landmark (a stone, for example), and measure the distance from it to his feet. Suppose that your shadow length was 1 m 40 cm
- Then measure the shadow of a tree. Here, everything is easier, because the wood still. For example, it is equal to 5 m 65 cm.
- Now, remember your height, say 1 m 80 cm if you measured your shadow, standing in heels, add their height to their height.
And here is the calculation
Multiply the length of the shadow from the tree on their own growth and divide by the length of your shadow:
The second method
Here you without an assistant can not do. Still need a pencil and all the same roulette.
You have to stand up so entirely to see the Christmas tree, and next to it stand your friend. Hold the pencil at arm's length with the tip up. Aiming, as when shooting, align the tip of the stylus to the top of the wood, and the nail of the thumb with the base of the trunk.
Now, turn the fist so that the pencil had taken a horizontal position. In the process we must make sure that the thumb remained in his place, and was still aligned with the bottom point of the barrel. The task of your helper – to move away from eating in the direction until, until you see that he was at the level of the tip of the pencil.
It remains only to measure the distance from the tree to your friend. This will be the height of your chosen tree.
