1. Answers will be integers on this exercise.
2. Users should be careful with their zeroes on metric conversions.

Real-life Applications

1. Units are used for many things such as cooking, placing new carpet, etc.
2. In real-life, good estimates are often more valuable than exact answers since real-life is not exact and mathematics only models real-life. Therefore knowledge of precision estimates can be utilized in most measurement situations.
3. Measurement is important for taking proper medicine. If one has an illness (whether serious or minor) they need to take their medicine and take it in the proper amount. If they take too little or too much then they are not going to get the proper benefit from it.
