Application may include

accurately measuring linear distance, mass, energy, and power with the appropriate measurement devices
determining significant digits (number of digits beyond the decimal point to determine accuracy of measurement or tolerance)
encouraging the use of modern electronic measuring equipment and probes (borrowing equipment or asking for guests to demonstrate [i.e., surveying])
using appropriate conversion techniques
converting U.S. customary units to International System (SI) units, and vice versa.

Use in context will solidify learning.

Process/Skill Questions:

Why is it important to make multiple measurements of the same object/item?
Why should one use significant digits in calculations/measuring?
What tools does one use to measure length, to measure mass, and to measure energy?
What case studies have shown the importance of proper conversion in engineering?
What can go wrong if one inaccurately converts between systems of measurement?
