Guide for the Use of the International System of Units (SI) Preface The International System of Units, universally abbreviated SI (from the French Le Système International d’Unités), is the modern metric system of measurement. Long the dominant measurement system used in science, the SI is becoming the dominant measurement system used in international commerce. The Omnibus Trade and Competitiveness Act of August 1988 [Public Law (PL) 100-418] changed the name of the National Bureau of Standards (NBS) to the National Institute of Standards and Technology (NIST) and gave to NIST the added task of helping U.S. -

Calculating the Surface Area of Your Landscape
Tips for Calculating Surface Area Area is defined in terms of square measures. The most commonly used area measurements are square feet and acres. Areas of : rectangle or square = length x width trapezoid = parallel sides A + B / 2 x height triangle = base x height / 2 circle = radius (1/2 diameter) squared x 3.14 oval = length x width x 0.8 The offset method is used to measure the area (square feet) of irregularly shaped areas. It reduces large areas to a series of smaller trapezoids that are equally spaced along a measured line. This method will determine the area to within 5%. The four steps in determining area by the offset method are as follows: Step 1: Determine the length line. This is the longest axis of the figure. Its endpoints should be labeled A and B. A B Step 2: Mark offset lines at right angles to the length line. Choose how many offset lines to use so that they divide line AB into equal segments and define regions amenable to calculation. For example, if the length line is 40 feet, a logical distance between offset lines would be 10 feet, which would end up with 4 measurements. If the shape of the area is uniform, fewer offset lines are needed. However, if the shape is irregular, more offset lines are needed. A B 10 ft. Step 3: Measure the length of each offset line. These are measured from one edge of the area to the other. A B 10 ft. 15 ft. 12 ft. 5 ft. Step 4: Add up the lengths of all offset lines and multiply by the distance between offset lines on the length line. -

The Bureau's overall goal is to strengthen and advance the Nation's science and technology and facilitate their effective application for public benefit. To this end, the Bureau conducts research and provides: (1) a basis for the Nation's physical measurement system, (2) scientific and technological services for industry and government, (3) a technical basis for equity in trade, and (4) technical services to promote public safety. The Bureau consists of the Institute for Basic Standards, the Institute for Materials Research, the Institute for Applied Technology, the Institute for Computer Sciences and Technology, and the Office for Information Programs. THE INSTITUTE FOR BASIC STANDARDS provides the central basis within the United States of a complete and consistent system of physical measurement; coordinates that system with measurement systems of other nations; and furnishes essential services leading to accurate and uniform physical measurements throughout the Nation's scientific community, industry, and commerce. The Institute consists of the Office of Measurement Services, the Office of Radiation Measurement and the following Center and divisions: Applied Mathematics — Electricity — Mechanics — Heat — Optical Physics — Center for Radiation Research: Nuclear Sciences; Applied Radiation — Laboratory Astrophysics - — Cryogenics ~ — Electromagnetics " — Time and Frequency ". THE INSTITUTE FOR MATERIALS RESEARCH conducts materials research leading to improved methods of measurement, standards, and data on the properties of well-characterized materials needed by industry, commerce, educational institutions, and Government: provides advisory and research services to other Government agencies; and develops, produces, and distributes standard reference materials. -

Handbook 133 – 2020 Appendix E. General Tables of Units of Measurement Appendix E. General Tables of Units of Measurement These tables have been prepared for the benefit of those requiring tables of units for occasional ready reference. In Section 4. Tables of Units of Measurement of this Appendix, the tables are carried out to a large number of decimal places and exact values are indicated by underlining. In most of the other tables, only a limited number of decimal places are given, therefore making the tables better adapted to the average user. Section 1. Tables of Metric Units of Measurement In the metric system of measurement, designations of multiples and subdivisions of any unit may be arrived at by combining with the name of the unit the prefixes deka, hecto, and kilo meaning, respectively, 10, 100, and 1000, and deci, centi, and milli, meaning, respectively, one-tenth, one-hundredth, and one-thousandth. In some of the following metric tables, some such multiples and subdivisions have not been included for the reason that these have little, if any currency in actual usage. In certain cases, particularly in scientific usage, it becomes convenient to provide for multiples larger than 1000 and for subdivisions smaller than one-thousandth. Accordingly, the following prefixes have been introduced and these are now generally recognized: yotta, (Y) meaning 1024 deci, (d), meaning 10-1 zetta, (Z), meaning 1021 centi, (c), meaning 10-2 exa, (E), meaning 1018 milli, (m), meaning 10-3 peta, (P), meaning 1015 micro, (µ), meaning 10-6 tera, (T), meaning 1012 nano, (n), meaning 10-9 giga, (G), meaning 109 pico, (p), meaning 10-12 mega, (M), meaning 106 femto, (f), meaning 10-15 kilo, (k), meaning 103 atto, (a), meaning 10-18 hecto, (h), meaning 102 zepto, (z), meaning 10-21 deka, (da), meaning 101 yocto, (y), meaning 10-24 Thus a kilometer is 1000 meters and a millimeter is 0.001 meter. -
