Presentation Transcript

  1. Using Scientific Measurements SI Units and Dimensional Analysis

  2. SI Units • Universal standard of measurements

  3. SI Units- Prefixes • Used to indicate values larger of smaller than the SI unit

  4. Dimensional Analysis • Method of solving problems using conversion factors • Conversion factor- ratio derived from the equality between two different units that can be used to convert from one unit to the other

  5. Solving Problems Using Dimensional Analysis • quantity sought= quantity given × conversion factor • Multiply all top numbers together • Divide by all bottom numbers Ex. How many quarter are in four dollars? 4 dollars x 4 quarters = 16 quarters 1 dollar

  6. Practice How many seconds are in a day? How many milliliters are in five liters?
