## Summary

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.

## Purpose

Convert measurement units

## Return value

A number in the new measurement system

## Syntax

``=CONVERT(number,from_unit,to_unit)``
• number - The numeric value to convert.
• from_unit - The starting units for number.
• to_unit - The ending units for the result.

## How to use

The 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, gallons into liters, and for many other unit conversions.

### Examples

The formulas below use the CONVERT function to convert yards to meters, Celsius to Fahrenheit, gallons to liters, and square meters to square yards:

``````=CONVERT(100,"yd","m") // returns 91.44
=CONVERT(22,"C","F") // returns 71.6
=CONVERT(1,"gal","l") // returns 3.79
=CONVERT(100,"m2","ft2") // returns 1076.39
``````

### Notes

• 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 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.
