I think you are right. Given the fact that measurement unit of rain is one-dimensional (in inch, cm, or mm...per year), your equation means:
Total Volume of rain poured on earth in a year= average rain on the planet in mm *surface area of the planet in square mm
No. of rain drops pouring on earth every year=Total Volume of rain poured on earth in a year in cubic mm/average volume of a rain drop in cubic mm
(average rain on the planet*surface of the planet)/volume of rain drop
