The Weight of Black Ash Boards calculator computes the weight of black ash boards based on the number and dimensions of the boards, and a density of 526.00 kg/m3 for dry black ash wood.
INSTRUCTIONS: Enter the following:
- (n) Number of black ash boards
- (L) Length of the boards
- (W) Width of the boards
- (T) Thickness of the boards
- (ρ) Density of Wood
Weight of Black Ash Boards (m): The function returns the weight in pounds. However this can be automatically converted to compatible units via the pull-down menu.
The Math / Science
Black Ash, Fraxinus nigra, is a durable hardwood. It is often used for various interior finishing such as cabinets. Strips of black ash wood can be flattened and woven to make baskets and chair seats. Dried black ash lumber has an approximate density of 526.00 kilograms per cubic meter (32.84 pounds per cubic foot).
Different types of wood have different naturally occurring densities. Because wood is a porous material, different kinds of wood can have more or fewer wood cells per volume of space. This defines the wood's density. Moisture is a major factor where wood boards are heavier if they have an increased water content. The water in wood can be free or bound, where free water can move through connecting cells to the end surfaces. Free water can be largely reduced through drying in kilns or dry storage. Bound water is within cells and is harder to remove. However, removing bound water increases the strength of the wood boards. That is why processed lumber is stronger than rough cut boards of the same dimensions. The formula for the weight of wood boards is as follows: M = ρ • n • L • W • T where: CAUTION: The following information is for calculating convenience with NO implied guarantees to the accuracy of the values listed.
