Conversion formula

The conversion factor from kilometers to centimeters is 100000, which means that 1 kilometer is equal to 100000 centimeters:

1 km = 100000 cm

To convert 10000 kilometers into centimeters we have to multiply 10000 by the conversion factor in order to get the length amount from kilometers to centimeters. We can also form a simple proportion to calculate the result:

1 km → 100000 cm

10000 km → L_(cm)

Solve the above proportion to obtain the length L in centimeters:

L_(cm) = 10000 km × 100000 cm

L_(cm) = 1000000000 cm

The final result is:

10000 km → 1000000000 cm

We conclude that 10000 kilometers is equivalent to 1000000000 centimeters:

10000 kilometers = 1000000000 centimeters

Alternative conversion

We can also convert by utilizing the inverse value of the conversion factor. In this case 1 centimeter is equal to 1.0E-9 × 10000 kilometers.

Another way is saying that 10000 kilometers is equal to 1 ÷ 1.0E-9 centimeters.

Approximate result

For practical purposes we can round our final result to an approximate numerical value. We can say that ten thousand kilometers is approximately one billion centimeters:

10000 km ≅ 1000000000 cm

An alternative is also that one centimeter is approximately zero times ten thousand kilometers.
