Units and Conversions
Units and Conversions This unit of the Metrology Fundamentals series was developed by the Mitutoyo Institute of Metrology, the educational department within Mitutoyo America Corporation. The Mitutoyo Institute of Metrology provides educational courses and free on-demand resources across a wide variety of measurement related topics including basic inspection techniques, principles of dimensional metrology, calibration methods, and GD&T. For more information on the educational opportunities available from Mitutoyo America Corporation, visit us at www.mitutoyo.com/education. This technical bulletin addresses an important aspect of the language of measurement – the units used when reporting or discussing measured values. The dimensioning and tolerancing practices used on engineering drawings and related product specifications use either decimal inch (in) or millimeter (mm) units. Dimensional measurements are therefore usually reported in either of these units, but there are a number of variations and conversions that must be understood. Measurement accuracy, equipment specifications, measured deviations, and errors are typically very small numbers, and therefore a more practical spoken language of units has grown out of manufacturing and precision measurement practice. Metric System In the metric system (SI or International System of Units), the fundamental unit of length is the meter (m). Engineering drawings and measurement systems use the millimeter (mm), which is one thousandths of a meter (1 mm = 0.001 m). In general practice, however, the common spoken unit is the “micron”, which is slang for the micrometer (m), one millionth of a meter (1 m = 0.001 mm = 0.000001 m). In more rare cases, the nanometer (nm) is used, which is one billionth of a meter.

There are two main standards used in the shop, English and SI (or Metric).

MEASURMENT THROUGH the AGES Steve Krar in This Age of Space
1 MEASURMENT THROUGH the AGES (Measuring while Manufacturing is the Key to Good Products) Steve Krar In this age of space exploration, manufacturing requires precision measurement in order to make spacecraft dependable and reliable. All parts in the spacecraft must be manufactured to exact measurements in order to be interchangeable and function properly in the conditions faced in space. To accomplish this, the craftsperson must use the best machinery, along with accurate tools to measure the work, and the skills to produce accurate work. Early Measuring Tools As early as 6000 B.C. humans used parts of a body as guide to estimate the dimensions for things. From this came the first standards of measurement such as the inch, hand, span, foot, yard, and fathom. These early tools were not very accurate since all products were made by hand and a fraction of an inch one way or another made little difference. Measurement has to do with distance that involves a standard and a means of applying that standard between two separated points. The first-recorded linear standards were used by the ancient Egyptians and Sumerians and their measurement standard was parts of the human body: • A cubit was the length of a forearm from point of elbow to end of the middle finger, or about 20 inches. • The digit was the width of a finger, or from .72 to .75 inches. • The palm was the width across an open hand at the base of the fingers, or about three inches. • At a later date, the Olympic cubit became a foot and was divided by the Greeks into 12 thumbnail breadths.

Systems of Units
1 SYSTEMS OF UNITS Foot‐Pound‐Second (FPS) System Since long, the foot-pound-second (fps) system of units has been used to measure dimensions and quantities of material. The fundamental units are the foot for length, the pound for weight, and the second for time. The FPS system has two variants, known as the American version and the Imperial version. Now-a-days none of the systems is being used by scientists (after implementation of SI units). The International System of Units (SI) is preferred because it is simple and convenient. However, FPS units are still used to some extent by the general public, especially in the United States and in India also. Units of Length There are different units such as thou, inch, hand, foot, yard, rod, pace, mile, furlong, fathom, etc. used to measure length. However, the conversion factors are not simple. Thou One thousandth of an inch is called thou. In the United States it is called mil. The plural of thou is thou’ and of mil is ‘mils’. Inch An inch was originally defined as the width of a man's thumb, but later on it was defined as the length of three barleycorns placed end to end. The word inch comes from the Latin word for one-twelfth (uncia). The Romans, when invaded in the year 43, brought the concept of the 12 inch- foot to England and since then it had been used. Earlier the inch was subdivided into halves, quarters, eighths, sixteenths, and other powers of 1 2 Elementary Pharmaceutical Calculations two; and also into hundredths (as in the caliber of fire-arms) or thousandths (called thou in the UK and mils in the US).

Lesson 1: Measurement and Accuracy
3 Lesson 1: Measurement and Accuracy Activity 1. a) Each group will use the four rulers shown below to measure and record the length of the line segment drawn at the bottom of the page. (Copy the line segment onto a piece of patty paper to perform the measurement.) When recording the measurement made with a particular ruler, each group should decide what degree of accuracy (i.e., smallest unit of measure) is appropriate for the recorded measurement with the given ruler. b) Individuals and groups will report their measurements to the class, and the class will discuss and try to account for discrepancies between these measurements. inches 0 1 2 3 4 5 6 inches 0 1 2 3 4 5 6 centimeters 0 1 2 3 4 5 6 7 8 9 10 11 12 13 14 15 centimeters 0 1 2 3 4 5 6 7 8 9 10 11 12 13 14 15 4 Remarks on units of measure, accuracy of measurements, and rounding. We will use either metric units (meter, centimeter, kilometer, etc.) or English or customary units (foot, inch, mile, etc.) to measure length.1 We will use the standard abbreviations for these units: meter = m, centimeter = cm, kilometer = km, foot = ft, inch = in, mile = mi Here are the basic facts about converting between metric and English units.2 1 in = 2.54 cm 1 cm = .3937 in 1 ft (= 12 in) = .3048 m 1 m (= 100 cm) = 3.28 ft = 39.37 in 1 mi (= 5280 ft) = 1.609 km 1 km (= 1000 m) = .621 m What does it means to measure the length of a line segment to a certain degree of accuracy? Suppose that we measure the length L of the line segment shown below with a ruler that is graduated in units of tenths of a centimeter (= millimeters), and we find that the length L of this segment is closer to the 12.7 centimeter mark than it is to L any other mark on the ruler.
