A bacillus, also called a bacilliform bacterium or often just a rod, is a rod-shaped bacterium or archaeon. Bacilli are found in many different taxonomic groups of bacteria.
40 mm : 0.004 mm :
x 1000 : x 1000
= 40,000 : 4 mm
= (40,000 mm/4mm) : (4 mm/4mm)
= 10,000 : 1
Thus, the the scale of the model the bacteria cell is 10,000:1.
