2. Welcome to the exciting world of: 3.03 BTS Measurement!

3. NO, Really- It IS Exciting!

4. Think about clothes, for example. If there were no standards used to make specific sizes, sneaker shopping would become a random search for the right fit. How much time would this take?

5. Our technological world has developed standard sizes and standard ways to measure many if its items. Let’s look into a bit of measurement history.

6. The Bible is a book containing many stories. One famous story is about a man who had to know how to measure.

7. The name of the man: Noah. They were given to Noah in the “Cubit” system. To make it the right size, Noah was provided with the measurements. In this story, Noah is told to build a huge ship called an Ark.

8. The CUBIT! A CUBIT is the distance from an elbow to the end of a middle finger. Look at your own personal cubit and compare it to someone who is near you.

9. The Cubit measurement was not standardized! Different people have different CUBIT sizes! Using the cubit system creates a major problem:

10. Many great things were built before measurement became widely standardized. Let’s look at some ancient building accomplishments before world standardized measurement.

11. Egyptian Pyramids on the Giza Plateau 2400 B.C.

12. Egyptian Temple at Karnak 2000 B.C.

13. Inside the Roman Coliseum Rome, Italy Last gladiator battles: 523 A.D.

14. Roman Coliseum- outside Built-300 A.D. WITH NO POWER TOOLS

15. Roman Coliseum- Inside The arena center was covered with a thick, wooden plank floor. It also had a retractable roof!

16. Medieval Castles Completed by Edward the 1st in 1287 A.D. This is Castle Conwy in North Wales

17. Medieval Measurement Edward the 1st also standardized much of the English Standard System of measurement in the 1300’s. His nickname was “Longshanks”

18. England, Power and Standardization England became the world’s first global super power in the 1600’s. The English needed to standardize measurement, time, latitude and longitude.

19. World Standardizations England had power throughout the world and much of their standardization ideas are still used today.

20. The English Standard System Length Measurement: Inches, Feet, Yards and Miles Latitude, longitude and time: The world’s Prime meridian is located at the Royal Observatory in Greenwich (gren-itch), England.

21. The English Standard System Weights & Liquid Measurement Ounces, Pound, Ton Ounces, Pint, Quart, Gallon How confusing! Temperature: Fahrenheit Speed: Miles per hour

22. The English Standard measurement system : comes from many sources. can be very confusing. requires memorization of many different sets of measurement standards. is the primary system in the U.S.A.

23. Can there be a better, easier way to measure? Is there a common sense standard which is really easy…. Like counting fingers and toes easy?? YES!

24. Officially adopted by France in 1795, it is called the: Metric Standard System of measurement

25. This system is based on the number 10, just like your fingers and toes! It is a much easier system to use, once you learn a bit about it.

26. The Metric System Metric Length Measurements: The system is based on the meter. Meters are about 39-1/2” long. A Millimeter is a small metric measurement. It is 1/1000 of a meter. A common pencil has a diameter of about 8 millimeters (8mm).

27. The Metric System Metric Length Measurements: The system is based on the meter. Meters are about 39-1/2” long. is 1/100 of a meter or 10 millimeters. 1 Centimeter is about the same size as a half of an inch (1/2”). A Centimeter (cm):

28. The Metric System Metric Length Measurements: is a relatively long distance. It is 1000 meters. This is about 2/3 of a mile. A Kilometer (km):

29. The Metric System Other Metric Measurements: are used to measure liquids.Liters: Kilograms: Celsius: are used to measure weight. is used to measure temperature. are used to measure speed.Kilometers per hour:

30. Measurement Review: Until recently, there was no widespread standard measurement. Despite a lack of standard measurements, many large, complex ancient buildings have been constructed. There are two worldwide measurement systems common today: English Standard and Metric.

31. Measurement Review: The English standard system is a collection from a variety of origins. English Standard requires more memorization of factual information then the metric standard. The Metric is based on the number 10 and is crafted to make it an easy system.

32. Standard measurement forms one of the most important foundation in technology. Make learning about measurement an important part in your study of technology.

33. Good Job!
