Interactive centimeters to micrometers conversion tool

The cm to μm converter below can be used to quickly and easily convert centimeters to micrometers. Simply enter the number of centimeters you want to convert and the calculator will output the corresponding value in micrometers.

Convert Centimeters to Micrometers

What is the conversion factor between centimeters and micrometers?

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 centimeters and micrometers is 10000, such as:

1 cm = 10000 μm

Following the formula above, we can see that there are 10000 micrometers for every centimeter, and for every micrometer, there are 110000 centimeters (1e-4 cm).

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

10000 μm1 cm = 1 cm10000 μm= 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 centimeter to micrometer, we will use the first fraction: 10000 μm1 cm so that centimeters are canceled out. We then multiply the value in centimeters by this fraction to get the result in micrometers (see example).

Note that cm 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).

Conversion factor = Unit you are converting toUnit you are converting from

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

10000 μm1 cm

Which is bigger, a centimeter or a micrometer?

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

  • 1 cm = 10000 μm
  • 10000 micrometers is bigger than 1 micrometer.
  • 1 centimeter is, therefore, bigger than 1 micrometer.
  • To be more specific, a micrometer is 10000 times smaller than a centimeter.

How to convert centimeters to micrometers?

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

For example:

  • 2 x 1 = 2
  • 495 x 1 x 1 x 1 = 495

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 centimeters into micrometers we multiply 1000 cm by the conversion factor of 10000 μm1 cm

1000 cm = 1000 cm x 1 = 1000 cm x 10000 μm1 cm = 1e+7 μm

By replacing the number 1 with the conversion factor, centimeters are canceled out and we get the result in micrometers. 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 centimeters are equal to 1e+7 micrometers.

Remember:

  • When converting from centimeters to micrometers, we use 10000 μm1 cm as a conversion factor.

Practice: centimeters to micrometers conversion

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

How to convert 34 centimeters to micrometers?

We multiply 34 by the factor of 1

34 cm = 34 cm x 1

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

34 cm = 34 cm x 10000 μm1 cm

We multiply 34 centimeters by the conversion factor. Having centimeters in the denominator allows us to cancel out the undesired units (cm) leaving only micrometers in the final result.

34 cm = 34 cm x 10000 μm1 cm
34 cm = 34 x 100001 μm
34 cm = 340000 μm

Answer: There are 340000 micrometers in 34 centimeters

How many micrometers are in 635 centimeters?

Multiply 635 by the conversion factor. Make sure the unwanted unit (cm) is in the denominator.

635 cm = 635 cm x 10000 μm1 cm

This allows us to cancel out the centimeters (cm) and leave the micrometers (μm)

635 cm = 635 cm x 10000 μm1 cm
635 cm = 635 x 100001 μm
635 cm = 6.35e+6 μm

Answer: There are 6.35e+6 micrometers in 635 centimeters
