The History of Measurements
Helicobacter pylori Some Historical Units of Measurement History of Measurement • Objects were initially measured for convenience, to aid commerce and prevent fraud. • The Egyptians among other civilizations were the first to begin recording measurements around 3200 BC. • Early measurement units were based on body parts or common objects. Historical Units of Length and their equivalence chart ➢ Digit: the breadth of a finger (Egyptian) ➢ Barleycorn: the length of a barleycorn seed ➢ Inch: the width of a man’s thumb or 3 barleycorns ➢ Foot: the length of a man’s foot ➢ Cubit: elbow to fingertip length (Egyptian) ➢ Yard: nose to fingertip length ➢ Mile: 5000 pedes (feet, Roman) ➢ League: 7500 pedes Historical Units of Mass/Volume and their equivalence chart ➢ Grain: the weight of a grain of wheat or barleycorn ➢ Pound (libra): ~5000 grains (Roman) or ~7000 grains (English) ➢ Talent: 100 libra ➢ Stone: 14 pounds (English/British) ➢ Troy Ounce: 1/12 of a pound ➢ Carat: weight of a carob seed The Cubit The cubit is the measure from your elbow to the tip of your middle finger when your arm is extended. The cubit was the measurement used by the Egyptians to build the pyramids. The Palm The palm is the width of your four fingers when they are placed together. The Fathom The fathom is the measure from fingertip to fingertip when your arms are stretched sideways as far as they will go. The fathom was used by sailors to measure the depth of water so that boats would not run aground. The Hand-span The hand-span is the measure from the tip of your pinky to the tip of your thumb when your hand is stretched out. -

SCIENTIFIC MEASUREMENTS © 2019, 2004, 1990 by David A. Katz. All rights reserved. A BRIEF HISTORY OF MEASUREMENT Measurement was among one of the first intellectual achievements of early humans. People learned to measure centuries before they learned how to write and it was through measurement that people learned to count. People of the Peking and Neanderthal periods had implements constructed from materials individually determined to be the right length or weight for a particular purpose. A tool that worked well became the model and standard for another. (See Figure 1) To measure distance, they used their fingers, hands, arms, legs, etc... Measurement of weights were based on use of certain containers or what a person or beast could haul. Each unit was separate and unrelated since their ability to count was not developed. Figure 1. A stone ax and stones cut to the same size by comparison Since humans have ten fingers, we learned to count measurements from the Hittite by tens, and ways were soon found to relate units to Museum in Cappadocia, Turkey. each other. Some of the most well known of the early units of measurement were: inch - the width of the thumb. digit - the width of the middle finger (about 3/4 inch) palm - the width of four fingers (about 3 inches) span - the distance covered by the spread hand (about 9 inches) foot - the length of the foot. Later expressed as the length of 36 -barleycorns taken from the middle of the ear (about 12 inches). cubit - distance from the elbow to the tip of the middle finger (about 18 inches). -

This measurement of approximately 4 inches is still used to calculate how tall a horse is. It is the ______________________________. 2. Tired of relying on the length of the previous king’s girdles in determining the length of this unit of measurement, Henry the First decreed: “Henceforth, the shall be the distance from the tip of my nose to the tip of my thumb.” 3. The most common unit of measurement in the United States, the Romans referred to it as “one- twelfth of a foot.” It roughly equals the width of a person’s thumb, but since 1959, the has officially equaled 2.54 Dcentimeters. 4. In 1812, Napoleon noted that the French people were still clinging to traditional units of measurement; even though the was officially adopted by the French government in 1795. This system of Dmeasurement originally derived its name from the Greek word “metron”, meaning “measure”. Today it is also known by the initials SI, or System International, and was legalized in the United States in 1866. 5. The is one of the earliest known units of measurement. It was the standard unit of measurement for thousands of years in many civilizations, though it has widely gone out of popular use today. -

A Brief History of Measurement
Eur. Phys. J. Special Topics 172, 25–35 (2009) c EDP Sciences, Springer-Verlag 2009 THE EUROPEAN DOI: 10.1140/epjst/e2009-01039-1 PHYSICAL JOURNAL SPECIAL TOPICS Regular Article A brief history of measurement M.E. Himbert LNE-LCM, Cnam-Metrology, Case I 361, 61 rue du Landy, 93210 La Plaine-Saint-Denis, France Abstract. The aim of this paper is to situate the subject of measurement and metrology in its historical and philosophical context. Everyone agrees that the numeration of objects and the quantification of the characteristics of some simple systems are very ancient practices encountered in any specific civilisation. Indeed the link between measurement and numeration comes from the beginnings. This is recalled here, as are the links between units and money, between references and authority. Then, the paper identifies and exhibits the different epistemological gaps occurred – or occurring – in the history of measurement in the western countries: • geometry versus arithmetics, • model versus experiment, • prediction versus uncertainty, • determinism versus quantum physics. Those gaps are described in relationship to the evolution of the internationally agreed system of units. 1 Measurement: Technology or philosophy 1.1 Measurement, experiment and knowledge Measurement leads to the expression of characteristics of systems in terms of numbers. As explained Lord Kelvin: “When you can measure what you are speaking about, and express it in numbers, you know something about it; but when you cannot measure it in numbers, your knowledge is of a meagre and unsatisfactory kind ...”. Indeed the aim of measurement is to give reliable knowledge on objects or concepts. Despite the fact that, in the present paper, the regular historical approach will be considered, one has first to address several transverse questions about experience, numerical value, and knowledge, which will be implicitly referred to hereafter.
