Centimeters in a kilometer

Answer 1

1 kilometer=100,000 centimeters
Prefix centi is used to denote sub multiplies of meter and uses factor 10-2 or 0.01

Prefix kilo uses factor 103 or 1000

First we convert centimeters to meters and then meters to kilometers:

1. 1 * 10-2 = 1 * 0.01 = 0.01 meters
2. 0.01 / 103 = 0.01 / 1000 = 0.00001 kilometers

Which gives us 0.00001 centimeters in 1 kilometer

Quick way to convert centimeters to kilometers is to divide value in centimeters by 100000
