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.

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.

  • English Customary Weights and Measures
    English Customary Weights and Measures Distance In all traditional measuring systems, short distance units are based on the dimensions of the human body. The inch represents the width of a thumb; in fact, in many languages, the word for "inch" is also the word for "thumb." The foot (12 inches) was originally the length of a human foot, although it has evolved to be longer than most people's feet. The yard (3 feet) seems to have gotten its start in England as the name of a 3-foot measuring stick, but it is also understood to be the distance from the tip of the nose to the end of the middle finger of the outstretched hand. Finally, if you stretch your arms out to the sides as far as possible, your total "arm span," from one fingertip to the other, is a fathom (6 feet). Historically, there are many other "natural units" of the same kind, including the digit (the width of a finger, 0.75 inch), the nail (length of the last two joints of the middle finger, 3 digits or 2.25 inches), the palm (width of the palm, 3 inches), the hand (4 inches), the shaftment (width of the hand and outstretched thumb, 2 palms or 6 inches), the span (width of the outstretched hand, from the tip of the thumb to the tip of the little finger, 3 palms or 9 inches), and the cubit (length of the forearm, 18 inches). In Anglo-Saxon England (before the Norman conquest of 1066), short distances seem to have been measured in several ways.

  • Duracor Rate Card
    Application Instructions Guidelines for Spot Spraying DuraCor® Herbicide for a 3 Gallon Tank For example, you went through the calibration procedure and applied 40 fluid ounces in the measured area. Therefore, your spray volume is 40 GPA. Look at the chart on the left for the amount of mix in 1 gallon of water. Assume you want to apply 12 fluid ounces DuraCor® herbicide per acre; the amount listed for your volume (GPA), and the application rate is 9.0 cc. Multiply this by 3 for your 3 gallon tank, and you would need to measure 27 cc (with a syringe) for your 3 gallon mix. Or, since there are 5 cc in a teaspoon, this would be 5.4 teaspoons in your mix.
