What is the term for the unit used to measure spray droplet size in pesticide applications?

Explanation:
Spray droplet size is measured in micrometers, called microns. Droplets produced by agricultural sprayers are extremely small, so using microns provides a precise scale—1 micron is one millionth of a meter. Millimeters, centimeters, and meters are far too large to describe these tiny droplets. Using microns also ties directly to drift and coverage considerations: smaller droplets (lower microns) tend to drift more with wind, while larger droplets (higher microns) reduce drift but may affect uniform coverage.
