To estimate the board feet from a log, measure the average diameter of the smaller part of the log in inches. Then, measure the length of the log in feet. Move the scale’s marker over to where these two measurements meet. Where the two measurements intersect is the approximate board foot output.
How many board feet is in a log?
How Much Lumber is in a Log? The board-foot contents of logs according to the International 1/4 Rule Diameter of log small end, inside bark Length of log (feet) 12 inches 45 70 13 inches 55 85 14 inches 65 100.
What is the formula for calculating board feet?
For instance a 2 x 6 also equals one board foot for each foot of length. Board footage is calculated by multiplying the nominal thickness in inches (T) by the nominal width in inches (W) by the actual length in feet (L) and dividing by 12. The formula is: T x W x L = Board ft.
How do you calculate log wood?
Volume of Wood The cubic feet, or volume, of a cylindrical log is given by the volume of a cylinder V=πhr2. A log with radius of 2 feet and height of 10 feet would have a volume of about 125.66 cubic feet (or ft3).
How much lumber can you get from a log?
An average urban tree about 20 inches in diameter at 4½ feet above the ground and with a 10-foot solid log should yield 150 to 200 board feet of lumber.
How many board feet can a log truck haul?
Load volumes ranged from 1,199 to 3,759 board feet by the Doyle rule and 1,655 to 4,030 board feet by the In- ternational rule, and from 342 to 689 cubic feet (table 1).
How do you calculate board feet for a project?
To determine board feet for your project, take the desired board’s thickness, width and length, and multiply them together. From there, you need to divide it by 144 to determine the number of board feet you need.
How do I calculate board feet in Excel?
Here is the relation: 1 board foot = 144 cubic inches = 1/12 cubic foot. Board foot formula = length * width * thickness. board foot = length(ft) * width(in) * thickness(in) / 144. board foot = length(ft) * width(ft) * thickness(in) / 12.
How many board feet are in a 1×8?
1” x 8” x 1′ = 0.67 bd. ft. 1” x 10” x 1′ = 0.83 bd.
What is the formula to calculate volume of the log timber?
Apply the formula for volume of a cylinder, V = π × r2 × h, where V is the log’s volume, r is the radius of the log and h is its height (or if you prefer, its length; the straight-line distance from one end of the log to the other).
How do you calculate volume of a log?
Smalian’s formula states that the volume of a log can be closely estimated by multiplying the average of the areas of the two log ends by the log’s length.
How do you calculate square feet for wood?
Step 1: Measure the width of your item in inches and then multiply times the height. Step 2. Multiply the width and height of all sides to be coated (including the top). Step 3: Add all of these totals together and divide by 144 to determine the total square feet you will need to cover.
How many feet must one be away from a tree to measure the amount of saw logs in it?
pacing 66 feet from the tree is usually an adequate distance measure. Figure 3. Using the diameter and height in 16-foot logs, read the volume of board feet in the tree.
What is board foot price?
Hardwoods are sold by the board foot, which is a calculation of the wood volume in the board. A board foot indicates a volume quantity equal to a board 12 inches by 12 inches by 1 inch, or one-twelfth of a cubic foot.
What length do you cut logs for lumber?
Find yourself a nice and straight stick, preferably green and hard like oak or ash. Use a tape measure and cut the stick to either 4 feet or 6 feet exactly. I like to use 4-foot-long sticks because most log lengths are divisible by 4 feet. Mark the stick by cutting a groove in it at 2-foot increments.
How many logs can a log truck have?
Though there may be a general range you can predict will fit; it is truly the weight capacity of your truck that is the number your need to be concerned with. For larger 3-axel trucks could see up to 80 longs on a truck with smaller trees or up to 65 logs for smaller trees.

How do you calculate wood material?
A single board foot is one square foot of wood that is one inch thick. You can measure board feet by multiplying length x width x thickness in inches, and then dividing by 144. If ordering a large amount by board feet, just multiply the total board feet needed by the price per board foot for the total cost.
How do you calculate wood for a project?
TIP: To calculate board feet: rough standard thickness X actual width X actual length divided by 144. Use the thickness of the material you intend to start with, not end with. For example, the 3/4″ top will start from 4/4 lumber. The legs will start from 6/4 lumber.
What is 200 board feet in square feet?
A 600 board foot kit will cover 600 square feet at 1 inch thickness or 300 square feet at 2 inches thick; a 200 board foot kit will cover 200 square feet at 1 inch thickness, and so on.
