Activity 3.1b Linear Measurement US
Introduction
The United States is the only developed country that does not use the International System of Units. The U S Customary units are the accepted units of measure. However, due to the global nature of the economy, SI units are also common. In order to participate in the global market, we must be able to understand and communicate using various measurement systems.
In this activity you will practice taking linear measurements using a standard ruler marked in US Customary units and correctly recording the measurements to reflect the precision of the measurement.

Conclusion
1. When you look at a drawing, how do you know if you are looking at U S Customary or SI measurements? Why is it important for an engineer to know this piece of information? U.S. Customary uses in., ft., yds., etc... The U.S. Customary doesn't have a simple formula for switching between units, unlike the metric system (SI Units). Engineers need to know this so they don't end up converting a foot into 10 in. or 100 centi-inches.
