Question

Change 5 cm to Km ?

Answer 1

As the prefix "centi" is a factor of 1⁄100, we can state 1 cm is equal to 0.01 m. The prefix"kilo" means a factor of 1000, we can write that 1 m is equal to 0.001 km. Thus, 1 cm equals to 0.01*0.001 part of 1 km, so
1 cm= 0.00001 km.,
5 cm= 0.00005 km.

Answer: 0.00005km.
