Nikon lens 18 - 55 mm means Millimeter or Meters? - 1

Gosh! Even if you don't use metric over there, which word has two m's?

Mm. The lens focal length ranges from 0-71 - 2.165 inches.

Mm is the SI abbreviation of millimetre.
1 metre = 1000 millimetres

If it were metres you would not have the strength to carry the lens!

1 meter is almost 3 feet. You do the math.

Whew…

M = meters mm=millimeters a 55 meter lens would probably be 55 * 39 inches long approx 180 feet long they can reduce that using mirror lenses and fold the path back and forth.

Yes dear it is
