Given that 1 meter = 1 x 109 nanometers, what is the diameter of the average cell in the human body, in nanometers?   the diameter of the average cell in the human body is 1 x 10-5 meters.    show your work.

To answer this question, you need to understand how to convert a unit. In this case, the conversion would be meter to nanometer. Since 1 meter is 10^9 nanometer, then to convert it you need to multiply it with 10^9nm/1m which was equal to 1.
The calculation would be:
(1 * 10^-5 m) * (10^9nm / m) = 1* 10^4 nano meter= 10,000 nanometer
