How to use CONVERT Function in Excel

The Excel CONVERT function converts a number in one measurement system to another. For example, you can use CONVERT to convert feet into meters, pounds into kilograms, Fahrenheit to Celsius, gallons into liters, and for many other unit conversions.

Syntax: =CONVERT (number, from_unit, to_unit)

The CONVERT function syntax has the following arguments:

  • Number (required argument) – The numeric value we wish to convert.
  • From Unit – This is the unit you are converting from. Quotations are necessary!
  • To Unit – This is the unit you are trying to convert to. Quotations are necessary!

Example: Let’s look at some Excel CONVERT function examples and explore how to use the CONVERT function as a worksheet function in Microsoft Excel:

Syntax:  =CONVERT(A2,B2,C2)


Based on the Excel spreadsheet above, the following CONVERT examples would return:

Syntax: =CONVERT(A3,B3,C3)
Result: 86

Syntax: =CONVERT(A4,B4,C4)
Result: 37.77777778

Syntax: =CONVERT(A5,B5,C5)
Result: 3.785411784

Syntax: =CONVERT(A6,B6,C6)
Result: 1076.391042

Syntax: =CONVERT(A7,B7,C7)
Result: #N/A

Syntax: =CONVERT(A8,B8,C8)
Result: 0.45359237

Syntax: =CONVERT(A9,B9,C9)
Result: 50

Syntax: =CONVERT(A10,B10,C10)
Result: 1609.344

Syntax: =CONVERT(A11,B11,C11)
Result: 62.13711922

Syntax: =CONVERT(A12,B12,C12)
Result: 16.66666667

Syntax: =CONVERT(A13,B13,C13)
Result: 39.37007874

Syntax: =CONVERT(A14,B14,C14)
Result: 120

Syntax: =CONVERT(CONVERT(A15,”ft”,”m”),”ft”,”m”)
Result: 23.22576


  • The CONVERT function is case-sensitive.
  • CONVERT will return the #N/A error when a unit string is not recognized.
  • CONVERT will return the #N/A error when a units are not compatible.
  • CONVERT will return the #VALUE! error when a number is not valid.
  • A number of measurement units were added to CONVERT in Excel 2013.
