1) The meter to km conversion = 103, therefore:

m2 to km2 = 106

Since the conversion goes small unit (meter) to larger unit (km), we must make the sign on the exponent be negative, hence 10¯6.

This means 4.26 x 104 m2 = 4.62 x 10¯2 km2

This creation of the negative can be seen in the following set-up which uses techniques explained previously:

2) The fm to cm conversion = 1013, therefore:

fm2 to cm2 = 1026

Since the conversion goes small unit (femtometer) to larger unit (centimeter), we must make the sign on the exponent be negative, hence 10¯26.

Therefore:

3.20 x 1010 fm2 x (1 cm2 / 1026 fm2) = 3.20 x 10¯16 cm2
