4. Ancient times, the leader declared their body parts to be units of measure

5. 1 foot thumb = 1 inch

7. Your queen is huge so your “pound” weighs more than our pound
Renessance comes along, and countries are sharing science, and other ideas. PROBLEM - our measurements do not match your measurements.
Your queen is huge so your “pound” weighs more than our pound
Therefore, our instructions need to be converted – a big math problem!

8. Scientists get together in Europe to share information
Scientists get together in Europe to share information. The measurement problem is something they want to solve. 1. Make MY king’s body parts the World’s measurements. No, make My king’s. No, Mine! Mine! No, we need to honor Our King. 2. How about we NOT honor anyone. Lets pick something EVERYONE has!

9. They agree to use things common to all
They agree to use things common to all! Length (meter) – based on the circumference of the Earth (40 million meters) Mass (gram)– based on the mass of one cubic centimeter of water Volume (liter) based on the size of a cube 10 cm cubed. That equals 1000 cc, or 1000 milliliters.

10. Countries around the world agree and SI (metric system) is born
Countries around the world agree and SI (metric system) is born. (SI is the abbreviation for the French term Système Internationale d'Unités). Even the U.S. agrees…later. Much later, oops, not at all.

11. S.I. Measurement The International System of Units (SI) is the standard measuring system for most scientists. SI combines prefixes and base units to define large and small quantities.
