  1. Metric System& SI System

  2. The standard for measurement in the scientific community today is the metric system. We use the metric system for 3 reasons: • Easy and convenient because it is universal • The rest of the world has been using it for the past 40 years • conversions between units are easy, because everything is done in multiples of ten. • 10, 100, 1000, 10000, etc. YOU FINISH!

  3. The SI system was adopted by the scientific community around 1960. • The SI system has seven base units one for each of the following: • length meter • mass kilogram • time second • electric current ampere • temperature Kelvin • amount of substance mole • luminous intensity candela

  4. The metric system tells how many, And the SI system tells us of what!

  5. -Length-The meter is the unit for length. We will always use the meter when discussing length. • 1km- 5 city blocks 1000m • 1m floor to doorknob • 1dm grapefruit .1m • 1cm button .01m • 1mm width of dime .001m • 1m bacteria cell diameter .000001m • 1nm thickness of RNA .000000001m

  6. -volume-Volume is the space occupied by matter. The SI unit for volume is meter cubed. The common unit of measure is the Liter. 1 liter = 1000 centimeters cubed.volume is dependent on temperature. (ex. ice) 1L a quart of milk 1mL 20 drops of water .001L 1cm cube of sugar .001 L 1L crystal of salt .000001 L

  7. -Mass- • Mass- quantity of matter an object containsWeight- measure of the pull of gravity of the earth on an object. • Mass  Weight • Mass is measured in grams. The SI unit of mass is the kg. A kilogram is the mass of one liter of water at 4C.

  8. 1kgsmall textbook 1000g • 1g dollar bill • 1mg10 grains of salt .001g • 1g particle of baking powder .000001g
