Demonstrate metrology used in manufacturing.

Demonstration should include measuring length, area, volume, and weight, using

• Society of Automotive Engineers (SAE) units (including fractions to decimals and vice versa)
• Système Internationale (SI) units

and converting SAE units to SI units and vice versa.

Measurement tools may include

• machinist rule
• U.S. ruler
• tape measure
• metric ruler
• architect or engineer scale
• weight scale
• micrometer
• calipers (digital, dial, and Vernier)
• dial indicator/gauge blocks
• measurement cups.

Process/Skill Questions:

• Why is there more than one system of measuring units?
• What are calipers used to measure?
• What are the consequences of failing to accurately convert units of measure?
• What unit of measure is most often used in U.S. manufacturing?
