Modern civilization cannot exist without measurement systems. Measurements are everywhere, and you use them every day. Every time you buy gas, check the outside temperature, or step on a weight scale, measurements are used to represent a quantity. The abilities to conduct, record, and convert measurements are necessary to understand our technological world and to carry on the business of living. Engineers of all disciplines are constantly required to work with measurements of a variety of quantities – length, area, volume, mass, force, time, temperature, electric current, etc. It is often necessary to be able to express those measurements in different units.
Research, explore, and develop your own understanding of unit conversion. Then, work with a team to create a lesson that shares what you learned with the class. Your lesson should make us think and be fun!
Your lesson must cover:
- The purpose of unit conversion
- Conversion factor formula
- Conversion of units in both SI and US Systems
- How to write numbers in the SI System
- Dimensional analysis
- Unit prefixes
- Rules of exponents
- Precision versus accuracy
- Significant figures
Essential Question:
What would happen if engineers did not follow accepted dimensioning standards and guidelines but, instead, used their own individual dimensioning methods?
