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 = 4x106
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 km2
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 = 1x107
