When considering calibration, what is the best unit for expressing actual travel speed?

Feet per minute is the most suitable unit for expressing actual travel speed, particularly in the context of calibration for aquatic pest control equipment. This unit provides a clear and practical measurement that allows operators to accurately determine how quickly their equipment is moving through the water or along a surface.

Using feet per minute helps in achieving precise calibration, which is essential for maintaining effective application rates of various treatments. This unit facilitates easier alignment with the operational parameters typically encountered in the field, ensuring that pesticide application is both efficient and environmentally responsible.

Other units mentioned, such as kilometers per hour and miles per KPI, may not offer the same level of relevance or practicality within the specific context of aquatic pest control in Florida. Ounces per minute refers to weight rather than speed and therefore would not apply to the measurement of travel speed at all.
