The metric system or International System of Units (SI) is based on seven base units for seven base quantities that are mutually independent. The quantities are: length (meter), mass (kilogram), time (second), electric current (ampere), thermodynamic temperature (Kelvin), amount of substance (mole) and luminous intensity (candela). All other units are derived from the base ones.
Level 1- The Staircase Method of Conversions-
Staircase method instructions-Look at the prefix you have and count how many steps you need to get to the prefix you want.
Then move the decimal that many steps and in the same direction to convert the number to the new unit.
Example 52 mm to km
starting at milli- it is 6 steps to the right to get to kilo
move the decimal six places to the left
so 52 becomes 0.000052km
Try these conversions using the staircase.
Level 2- Metric Conversions using the Factor Label Method
Using the factor label method and NYS Reference Table C (a Prefix Table). What you need to know is the prefix is the base unit times that factor. So when you set up the conversion just know that the factor always goes with the base unit and the unit that contains the prefix is always 1.
