Measurement Systems

This article explores the history and structure of measurement systems, emphasizing the differences between the English and Metric systems. Early systems of measurement were based on human anatomy and simple objects, such as the foot or a pail. The article provides essential conversions and approximate visualizations to help readers grasp the Metric system's three basic units: grams, liters, and meters. Additionally, it highlights the inconsistencies of the English system and the need for a universal standard of measurement, especially in the modern context.

  1. Measurement Systems

  2. EARLY SYSTEMS

  3. Measurements are relative • Foot = human foot • Inch = 3 barley corns • Yard = nose to outstretched fingertip • Mile = 1,000 paces • Gallon = simply the name for a pail

  4. Even God needs measuerments • Genesis 7 • Cubit = elbow to tip of mid finger

  5. Need for Consistency

  6. The English System

  7. Do you know our current system? • How many inches in a foot? • How many feet in a yard? • How many feet in a mile? • How many ounces in a cup? • How many cups in pint? • How many pints in a quart?

  8. The English System cont. • How many quarts in a gallon? • How many cups in a gallon? • How many ounces in a pound? • How many pounds in a ton? • How many mass ounces in a ton? • Are fluid ounces and weight ounces the same? • What is the abbreviation for a pound?

  9. CONFUSED????

  10. Need for simplicity Metric system “BORN” August 1, 1793 in France

  11. THE METRIC SYSTEM • First legal to use in the USA in 1866 • International acceptance by 1875 • Britain mandates use in 1965 • Canada in 1970 • Today only major country in the world that does not legally require its use is ……..

  12. THE U.S.A.

  13. ONLY 3 BASIC UNITS: • MASS (WEIGHT) = GRAM • VOLUME = LITER • DISTANCE = METER

  14. KILO = 1,000 HECTO = 100 DECA = 10 MEGA = MILLION DECI = .1 (1/10) CENTI = .01 (1/100) MILLI = .001 (1/1000) MICRO = one millionth NANO = one billionth PREFIXES

  15. English to Metric conversions • 1 gallon = 3.78 liters • 1 pound = 453 grams • 1 inch = 2.54 centimeters • 1 foot = .3048 meters • 1 yard = .91 meters • 1 mile = 1, 609 meters

  16. Only need to know APPROXIMATES

  17. Visualize: • 1 gram = weight of a small paperclip • 5 gram = weight of a nickel • 1 kg = 2.2 lbs = approx. weight of textbook • 1 mg = weight of a piece of dust

  18. Visualize: • 1 m = length of a baseball bat, golf club, etc… • 1 mm = thickness of an ID card • 1 cm = width of little finger / pencil • 1 km = 5 city blocks (8 blocks = 1 mile) • 1 ml = single drop of liquid / teardrop

  19. Metric to metric CONVERSIONS State the relationship and then determine direction to move decimal point Exp kg to g would be 1000 to 1 move to the right THUS: 12kg equals 12000 grams and 12000g equals 12kg

  20. DIRECTION • If larger to smaller unit move decimal to right • If smaller unit to larger unit move to left
