Excel CONVERT function

Author: Siluvia Last Modified: 2022-04-08

The CONVERT function converts a given number from one measurement system to another.


CONVERT(number, from_unit, to_unit)


  • Number (required): It is the value to be converted.
  • From_unit (required): The original unit for “number”.
  • To_unit (optional): The unit to convert the “number” to.
In Excel, there are numbers of measurement units. Tables below show the units for each category that can be applied to the “from_unit” and “to_unit” arguments of the CONVERT function. Go to know more....


1. The #N/A error occurs when any of the following conditions is met:
-- “From_unit” and “To_unit” are incompatible (not in the same measurement system group).
-- Either of the units is not recognized.
2. The #VALUE! error occurs if the supplied “number” argument is nonnumeric.
3. This function is case-sensitive.

Return value

It returns a complex number as text.


Supposing numbers in the table below are showed in meters, to convert them to yards, you can apply the CONVERT function to get it done.

Select a cell (says D6 in this case), enter the formula below and press the Enter key to convert the first meter to yard. Select this result cell and then drag its AutoFill Handle down to get other results.



1) For the “from_unit” and “to_unit” paraments, you need to use the abbreviations of the measurement names instead of using the full names. Click to know the measurements names and their corresponding abbreviations.

For example, if you apply the formula below, it will return an error value of #N/A.


2) The text abbreviations for the “from_unit” and “to_unit” arguments are case sensitive.

3) You can convert between different units by changing the “from_unit” and “to_unit” paraments in the formula.
