# How to convert length units to inverse cm

• agentas
In summary, the formula for converting length units to inverse cm is 1/x, where x is the length in cm. This means that any length unit can be converted to inverse cm using this formula, including units in scientific notation. Converting length units to inverse cm is useful in scientific research, particularly in spectroscopy and molecular physics, and the conversion factor is 1/x.

how to convert length units to inverse cm.For example arngstroms,nanometers to cm^-1.Thanks

Please elaborate what you are trying to do.

In general - you can't, as one is a length unit, other is a spatial frequency unit. Different things.

i want to use it with Fabry-Perot interferometer

Well, you could have barns per centimer, or something like that. Not sure why you'd want it, but you cold.

Converting length units to inverse cm involves converting the unit of length to cm first, and then taking the reciprocal of that value.

To convert from angstroms to inverse cm, we can use the conversion factor 1 Å = 10^-8 cm. This means that 1 cm is equivalent to 10^8 Å. To convert to inverse cm, we simply take the reciprocal of this value, which is 10^-8 cm^-1.

Similarly, to convert from nanometers to inverse cm, we can use the conversion factor 1 nm = 10^-7 cm. This means that 1 cm is equivalent to 10^7 nm. To convert to inverse cm, we take the reciprocal of this value, which is 10^-7 cm^-1.

In general, to convert any unit of length to inverse cm, we can use the conversion factor 1 cm = 10^x, where x is the power of 10 associated with the unit. For example, 1 meter (m) is equivalent to 10^2 cm (since 1 m = 100 cm), so to convert to inverse cm, we take the reciprocal of this value, which is 10^-2 cm^-1.

It's important to note that inverse cm is a unit commonly used in spectroscopy to represent wavenumbers, which are the reciprocal of wavelength. This unit is often used to describe the energy levels of molecules and atoms, and is especially useful in the study of infrared and Raman spectroscopy.

## 1. What is the formula for converting length units to inverse cm?

The formula for converting length units to inverse cm is 1/x, where x is the length in cm. This means that to convert a length unit to inverse cm, you simply divide 1 by the length in cm.

## 2. Can any length unit be converted to inverse cm?

Yes, any length unit can be converted to inverse cm using the formula 1/x, where x is the length in cm. This includes units such as meters, feet, inches, and miles.

## 3. How do I convert a length unit to inverse cm in scientific notation?

To convert a length unit to inverse cm in scientific notation, you can use the same formula of 1/x, where x is the length in cm. You can then express the result in scientific notation by moving the decimal point to the right until there is only one non-zero digit to the left of the decimal point.

## 4. Why would I need to convert length units to inverse cm?

Converting length units to inverse cm is useful in scientific research, particularly in the fields of spectroscopy and molecular physics. Inverse cm is often used as a unit of frequency in these fields, and converting length units to inverse cm allows for easier comparison and analysis of data.

## 5. Is there a conversion factor for converting length units to inverse cm?

The conversion factor for converting length units to inverse cm is 1/x, where x is the length in cm. This means that to convert a length unit to inverse cm, you simply divide 1 by the length in cm.
