Linear Measurement: Conversion

Today Portable 10 is learning how to convert, or change, one unit of measurement to another.
Converting units of measure can be tricky.  You must first ask yourself, "Will the number change into a bigger number, or smaller number?" In other words, you need to decide if you are going to add zeros or add decimals to convert a number correctly.  For example:
  • 1 mm = 0.1 cm 
  • 1 cm = .01 m
  • 1 m = .001 km
OR
  • 1 cm = 10 mm
  • 1 m = 100 cm
  • 1 km = 1000 m
Remember, if you are changing a larger unit of measure to a smaller unit of measure, the number will be larger.  
For example: 25cm = 250 mm because it takes 10mm to make 1cm.

Also remember that if you change a smaller unit of measure to a bigger one, the number will be smaller.
For example: 25cm = 0.25m because it takes 100cm to make 1m.

Good luck!
