# Excel CONVERT Function

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.

**number**- The numeric value to convert.**from_unit**- The starting units for number.**to_unit**- The ending units for the result.

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:

### 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 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.
