Question

A diameter of about 10nm. Express this diameter in meters, millimeters and micrometers.

Answer 1

Nanometers are on the order of 10^-9 meters

10nm = 10 x 10^-9 = 1.0 x 10^-8 meters

Micrometers are on the order of 10^-6 meters so:

10 nm = 10 x 10^-3 μm = 1.0 x 10^-2 μm

millimeters are on the order of 10^-3 meters so:

10 nm = 1.0 x 10^-5 mm

It helps to count out how many spaces you will have to move the decimal point left or right.
