Distance measuring units include the U.S. standard, (inch, feet, yard), decimal-inch (tenth, hundredth, thousandth, ten-thousandth), or the metric (millimeter, centimeter, meter). Being able to measure distance or determining if something is square are integral parts of many projects. This can include weekend do-it-yourself jobs to major landscaping and construction projects. While measuring cannot be done without some variation, errors can be reduced by following basic principles covered in this course.
•Describe the difference between errors and mistakes as they relate to measuring
•List ways to increase measuring accuracy
•Describe the parallax error
•Identify basic unit measurements for U.S. Standard, Decimal-Inch, and International System of Units, or SI (metric)
•Describe how to measure an angle
•Differentiate between the architectural and engineering scales
•Describe how to determine if something is square
