What is the conversion factor between kilometers and centimeters?

A conversion factor is used to change the units of a measured quantity without changing its value. It represents the ratio (or fraction) that expresses the relationship between two different units. A conversion factor is always equal to 1.

The relationship between kilometers and centimeters is 100000, such as:

1 km = 100000 cm

Following the formula above, we can see that there are 100000 centimeters for every kilometer, and for every centimeter, there are 1100000 kilometers (1e-5 km).

To convert from kilometers to centimeters, we turn our formula into a conversion factor that is equal to 1.

100000 cm1 km = 1 km100000 cm= 1

Both these fractions are equal to 1. The numerator and the denominator are equivalent, they are just expressed in different units.

Because we are converting from kilometer to centimeter, we will use the first fraction: 100000 cm1 km so that kilometers are canceled out. We then multiply the value in kilometers by this fraction to get the result in centimeters (see example).

Note that km is in the denominator (bottom) of the conversion factor. This is important, you always want to have the unit you are converting from at the bottom and the unit you are converting to in the numerator (top).

You will find below how to use this ratio to convert from km to cm. Just remember for now that the conversion factor for converting from kilometers to centimeters is:

100000 cm1 km

Which is bigger, a kilometer or a centimeter?

When it comes to measurements, there can be some confusion over which is bigger, a kilometer or an centimeter. To find out which one is larger, we must first convert one unit to the other and then compare them.

  • 1 km = 100000 cm
  • 100000 centimeters is bigger than 1 centimeter.
  • 1 kilometer is, therefore, bigger than 1 centimeter.
  • To be more specific, a centimeter is 100000 times smaller than a kilometer.

How to convert kilometers to centimeters?

Multiplying any value by 1 will get you the same value back. You can do that one time or multiple times.

For example:

  • 80 x 1 = 80
  • 692 x 1 x 1 x 1 = 692

Multiplying by 1 is the first step in any unit conversion problem. The second step is to replace the number 1 with the conversion factor that is also equal to 1.

For example, if we want to convert 1000 kilometers into centimeters we multiply 1000 km by the conversion factor of 100000 cm1 km

1000 km = 1000 km x 1 = 1000 km x 100000 cm1 km = 1e+8 cm

By replacing the number 1 with the conversion factor, kilometers are canceled out and we get the result in centimeters. And since the conversion factor is equal to 1, multiplying it with the original value won't change its magnitude and will only change its unit.

Based on this, we can conclude that 1000 kilometers are equal to 1e+8 centimeters.

Remember:

  • When converting from kilometers to centimeters, we use 100000 cm1 km as a conversion factor.

Practice: kilometers to centimeters conversion

Try answering the following questions without using our custom conversion calculator. Knowing how to convert manually between kilometers and centimeters could prove to be useful, so give it a shot. Once you are confident you can convert kilometers to centimeters, there is no harm then in taking full advantage of the tools available to you.

How to convert 43 kilometers to centimeters?

We multiply 43 by the factor of 1

43 km = 43 km x 1

We replace the number 1 with the conversion factor for kilometers to centimeters

43 km = 43 km x 100000 cm1 km

We multiply 43 kilometers by the conversion factor. Having kilometers in the denominator allows us to cancel out the undesired units (km) leaving only centimeters in the final result.

43 km = 43 km x 100000 cm1 km
43 km = 43 x 1000001 cm
43 km = 4.3e+6 cm

Answer: There are 4.3e+6 centimeters in 43 kilometers

How many centimeters are in 790 kilometers?

Multiply 790 by the conversion factor. Make sure the unwanted unit (km) is in the denominator.

790 km = 790 km x 100000 cm1 km

This allows us to cancel out the kilometers (km) and leave the centimeters (cm)

790 km = 790 km x 100000 cm1 km
790 km = 790 x 1000001 cm
790 km = 7.9e+7 cm

Answer: There are 7.9e+7 centimeters in 790 kilometers
