## Purpose

## Return value

## 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
```

### Measurement units

The tables below show the units available to the CONVERT function in each category. In all cases, Unit can be used for either from_unit or to_unit in the same category. *Note: the CONVERT function is case-sensitive.*

### 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.
