Questionnaire FOREST PRODUCTS CONVERSION FACTORS Questionnaire FOREST PRODUCTS CONVERSION FACTORS Please list the name of your country here If these data are only representative of a particular segment of a country, please specify Correspondents name, institute Deadline: 15 September 2016 Note: The data on conversion factors are to be filled in directly in the data tables (blue text) for the eight categories of factors. The black text is the explanatory text taken from the last UNECE/FAO Forest Products Conversion Factors publication (ECE/TIM/DP/491).There are eight sections of this questionnaire, each with a table for entering your conversion factors. The most important factors are in rows marked in green on the left, please prioritise these. Correspondents are encouraged to read the explanatory text prior to entering factors in each section. The questionnaire is pre-filled with the data from ECE/TIM/DP/49. If data on your country from this study is already present, please feel free to overwrite the old figures for your country with any updated figures and to fill in any fields which were previously blank. The questionnaire was developed by the UNECE/FAO Conversion Factors Task Force in 2008 and every attempt was made to include factors that the Task Force thought were important, however, if something important is missing, please feel free to write it into the questionnaire in the relevant section. Please feel free to contact the project coordinator (Matt Fonseca) at the UNECE/FAO Forestry and Timber Section if you have any questions or need assistance with interpreting questions: Email: [email protected] Phone: +41.22.917.1846 1 ECE/TIM/DP/49, Forest Products Conversion Factors for the UNECE Region can be downloaded at: http://www.unece.org/fileadmin/DAM/timber/publications/DP-49.pdf ii ____________________________________________________________Forest products conversion factors questionnaire 2016 C O N T E N T S (Questionnaire tables are highlighted in yellow) Page List of Abreviations .......................................................................................................................................................... iii INTRODUCTION .......................................................................................................................................................... 1 1.

  • Calculating Board Feet Board Feet Linear Feet Z "Board Feet" Is a Measurement of Lumber Square Feet Volume
    Calculating Board Feet board Feet linear feet z "Board Feet" is a measurement of lumber square feet volume. z A board foot is equal to 144 cubic inches of wood. TED 126 Spring 2007 z Actually it's easy to calculate using the following formula: Bd. Ft. = T (inches) x W (inches) x L (feet) / 12 2 Board Feet Board Feet z When you are figuring up board feet, keep in mind a waste factor. Bd. Ft. = T (inches) x W (inches) x L (feet) / 12 z If you purchase good clear material add about 15% for waste, Bd. Ft. = T (inches) x W (inches) x L (inches) / 144 z if you elect to use lower grade material you will have to allow for defects and more wasted material ---add about 30%. 3 4 Board Feet and Linear feet Board Feet and Linear feet z A linear foot is a measure of length 12 inches z To convert linear feet to board feet: long and a Thickness” x Width” x Length’ ÷ 12 z board foot is a number calculated by determining the volume of a board that is 12 z To convert board feet to linear feet: inches wide and 1 inch thick. • In other words, a 1" x 6" board that measures 24" 12 ÷ Thickness” x Width” x Board Foot long is exactly one board foot. (width" x thickness" x length' / 12) 5 6 1 Linear feet and Square Feet The math…. z It is not possible to convert linear footage into z A Linear Feet is just a measurement of square footage because a linear foot is only one length and does not take into account its dimension and a square foot is two dimensions, width or thickness.

  • Feasibility Analysis of a Small Log Sawmill in Southeast Alaska
    1 Feasibility analysis of a small log sawmill in Southeast Alaska Executive Summary Unlike most Southern Yellow Pine sawmills, a small log mill in Southeast Alaska that manufactured lumber from 60-year old trees, would not be profitable. There are many additional operating costs in the remote forests of Southeast Alaska that the Southern Yellow Pine sawmills do not incur. The two most costly disadvantages are; 1. An additional $SO per thousand board feet of lumber that is required to transport lumber from Southeast Alaska to the Pacific Northwest and, 2. The lack ofany reasonable economy of scale. The small timber sale volume projected to be available to the manufacturing industry in Southeast Alaska is inadequate to support more than a single mid-size sawmill. Consequently the regions sawmills will not produce any income from the residual products - chips, sawdust and bark. The chips are currently barged to pulp mills in the Pacific Northwest and Canada, while the Yellow Pine sawmills can deliver chips to nearby pulp mills at a much lower cost than the Alaska sawmills. Similarly, there are no fiberboard plants to utilize the sawdust from Southeast Alaska sawmills and there is no market for the bark in Southeast Alaska. Instead, most ofthe sawdust and bark must be disposed of in landfills. Introduction The purpose of this analysis is to compare several financial estimates of the feasibility of manufacturing lumber from immature young growth timber in Southeast Alaska. Four sawmill proformas are 1 examined : 1. A summary of five actual Southern Yellow Pine sawmills. This proforma was used because much of the rhetoric surrounding the Secretary of Agriculture unilateral decision to transition to 60+ year old Alaska young growth was based on assertions that Yellow Pine sawmills harvest their 2 timber before age 60 • Other than the obvious difference in tree species, the yellow pine region has much different logistic issues than Southeast Alaska.

  • Useful Forestry Measurements Acre: a Unit of Area Equaling 43,560
    Useful Forestry Measurements Acre: A unit of area equaling 43,560 square feet or 10 square chains. Basal Area: The area, usually in square feet, of the cross-section of a tree stem near its base, generally at breast height and inclusive of bark. The basal area per acre measurement gives you some idea of crowding of trees in a stand. Board Foot: A unit of area for measuring lumber equaling 12 inches by 12 inches by 1 inch. Chain: A unit of length. A surveyor’s chain equals 66 feet or 1/80-mile. Cord: A pile of stacked wood measuring 4 feet by 4 feet by 8 feet when originally conceived. Cubic Foot: A unit of volume measure, wood equivalent to a solid cube that measures 12 inches by 12 inches by 12 inches or 1,728 cubic inches. Cunit: A volume of wood measuring 3 feet and 1-1/2 inches by 4 feet by 8 feet and containing 100 solid cubic feet of wood. D.B.H. (diameter breast height): The measurement of a tree’s diameter at 4-1/2 feet above the ground line. M.B.F. (thousand board feet): A unit of measure containing 1,000 board feet.

Price $1; (Add 25 percent additional for other than U.S. mailing). Stock No. 003-003-01654-3 Library of Congress Catalog Card Number: 76-600055 Foreword "Weights and Measures," said John Quincy Adams in 1821, "may be ranked among the necessaries of life to every individual of human society." That sentiment, so appropriate to the agrarian past, is even more appropriate to the technology and commerce of today. The order that we enjoy, the confidence we place in weighing and measuring, is in large part due to the measure- ment standards that have been established. This publication, a reprinting and updating of an earlier publication, provides detailed information on the origin of our standards for mass and length. Ernest Ambler Acting Director iii Preface to 1976 Edition Two publications of the National Bureau of Standards, now out of print, that deal with weights and measures have had widespread use and are still in demand.
