What does FPM stand for in the context of calibration arithmetic?

FPM, in the context of calibration arithmetic, stands for "Feet per minute." This unit of measurement is commonly used to quantify the speed or velocity of various processes, including the movement of fluids, machinery, or in this case, the application of pest control substances. Understanding this unit is essential for accurately calibrating equipment to ensure that the correct amount of product is applied over a specified area within a given timeframe. This aids in achieving effective pest control while minimizing waste and environmental impact. The other options refer to different measures or misrepresented units not typically used in this specific context.
