Fundamentals of Refrigeration: Length and Width

To be a competent refrigeration professional, one must conquer the daunting challenge of mathematics. Whether assessing the volume of a vessel or performing a load calculation, mathematical aptitude is a necessary skill to possess.

The length or width of an object is a linear measurement. Length is always measured as a straight-line distance between two points. In the United States, common units for measuring length and width are inches, feet, yards, and miles. The metric system, which is widely used outside of the US, uses centimeters, meters, and kilometers. Units are often selected based on the distance being measured. For example, it would be typical to measure the length of an ammonia pipe in feet. But if we were to measure the length of an interstate highway, it would be more appropriate to use miles.
