Product labels and other information you use in pest management offer measurements in both the English and the Metric values, and working with these can be confusing. This resource provides you with all the conversions you may need to go from one to another, as well as lists of the abbreviations commonly used with measurements. There also are examples of how calculate needed measurements, such as volume or area of sites you may need to treat, where calibrating the application is important.
