1. The Metric System The Meter Is Born 3 Major Systems of Units Derived Quantities

2. The Meter Is Born  Meter: 1/10,000,000 the distance from the North Pole to the Equator. Based on the longitudinal meridian including Dunkirk and Barcelona. Standard measurement of LENGTH. Serves as the basis for the standard unit for VOLUME and MASS.  One cubic decimeter = ONE LITER (VOLUME)  One cubic centimeter of water = ONE GRAM (MASS)

3. The Liter is Derived from a 1/10 of a Meter.

4. One Cubic Decimeter One Cubic Centimeter

5. The Liter is Derived from a 1/10 of a Meter. One Cubic Decimeter IS a LITER. And, is 1000 Cubic Centimeters

6. The Gram is Derived from 1/1000 of a Cubic Decimeter of Water

7.  One cubic centimeter filled with water has the mass of one GRAM.

8. 3 Major System of Units with 7 Basic Quantities SI (System International) MKS (meter, kilogram, second) 1. Time – sec 2. Mass – kilogram 3. Length – meter 4. Temp. – Kelvin 5. Current – ampere 6. Amount of Substance – mole 7. Luminous Intensity - candella CGS (centimeter, gram, sec.) 1. Time – sec 2. Mass – gram 3. Length – centimeter 4. Temperature – Kelvin 5. Current - ampere 6. Amount of Substance – mole 7. Luminous Intensity – candella Imperial or British 1. Time – sec 2. Mass – slug 3. Length - foot 4. Temp. – Fahrenheit 5. Current – ampere 6. Amount of Substance – mole 7. Luminous Intensity – candella The __pound___ is Exactly 453.59237 grams by definition. The ___foot___ is Defined as exactly 0.3048 meters since 1959

9. Derived Quantities  Any quantity that is made from a combination of the basic quantities Example: Velocity = length (distance) traveled / change in time Units  MKS = m/s  CGS = cm/s  Imperial = ft/s Others Velocity units _______, ________, ________
