Aim: How to Convert from One unit to Another. What is a Unit Conversion?  A unit conversion is a changing of one unit to another.  Unit Examples: 

Measurement  A number and a unit that define a quantity  Time  Distance  Length  Volume  Temperature.

Engineering Units of Measure

 Sometimes, non-SI units are used  Liter, Celsius, calorie  Some are derived units  They are made by joining other units  Speed = miles/hour (distance/time)
