Using Scientific Measurements SI Units and Dimensional Analysis
SI Units • Universal standard of measurements
SI Units- Prefixes • Used to indicate values larger of smaller than the SI unit
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
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
Practice How many seconds are in a day? How many milliliters are in five liters?
