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.
