HOW?!
Different species of bees are different lenghts. An adult worker bee is 9mm - 18mm (0.35in - 0.71in) in length. Slightly larger, a typical queen bee is 18mm - 20mm in length (0.71 - 0.79) long.
Females are larger than males and grow to about 18mm in length.
18mm is 0.70866 inches.
18mm is 1.8cm
18mm = 0.018m
about an inch and a half
7cm is much more than 18mm. Through conversions, 7cm is the same as 70mm, and 18mm is 1.8cm.
Area of a rectangle=length x width. Length=18, and Width=8. 18*8=144 mm.2
This describes the focal length range of the lens. It means that the lens can be set between 18mm (a wide angle which takes in a larger field of view) and 200mm (a telephoto, which creates a narrower field of view). ******* Note: the above is certainly true for 35mm format, but focal length is relative to the format. For 4x5 cameras, the equivalent "normal" focal length is around 200mm.
If the radius of a circle is 18mm, its diameter is: 36mm
18MM Socket
That's in the right order.
