Question
Anton van Leeuwenhoek, a 17th century pioneer in the use of the microscope, described the microorganisms he saw as "animalcules" whose length was "25 thousandths of an inch."
How long were the animalcules in meters?
Based on the magnitude of your answer to (a), what is the most convenient metric prefix used to express the length of an average animalcule, and what is the length of an animalcule using this unit of length? (Example: an object that is 0.0254 m long would be most conveniently expressed as 2.54 cm).
Explanation / Answer
25 thousandths of an inch = 1/ 25000 = 0.00004 inches
we know that, 1 meter = 39.37 inches.
=> 0.00004 inches = 1.016 x 10-6 m <<<<<<<<-----------(ANSWER)
It can be conveniently expressed as 1.016 micro meters.
( since 1 micro meter = 10-6 meter )
