The formulas for conversion are represented below:

km = cm / 100000

Example: 5 Centimeters in Kilometers:

km = cm / 100000

km = 5 / 100000

km = 0,00005

cm = km * 100000

Example: 10 Kilometers in Centimeters:

cm = km * 100000

cm = 40 * 100000

cm = 4000000 = 4x10^{6}

Considering that 1 Centimeter is equivalent to 0.00001 Kilometers, you can use a rule of three to obtain that **7 Centimeters equal 0.00007 Kilometer**.

1 cm - 0,00001 km

7 cm - x

Apply the rule of three and get:

x ~~cm~~ = 0,00007 km^{2}

x = 0,00007 km = 7x10^{-5} km

If there are 100000 Centimeters for every 1 Kilometer, just multiply the number of Kilometers (100) by 100000, so you will obtain that **100 km equals 10,000,000 cm**. Observe the calculation below:

cm = km * 100000

cm = 100 * 100000

cm = 10000000 = 1x10^{7}
