# Convert area
## Description
This operation converts values from one unit of measurement to another, such as square feet, acres, square meters, and even smaller or less common units used in physics (like barns or nanobarns).
***
## Data types
These are the input/output expected data types for this operation:
### Input data
 - Values whose unit of measurement you want to transform. They must be strings representing numbers.
### Output data
 - Resulting values after transforming them to the selected unit of measurement.
***
## Parameters

## Example
Suppose you want to convert a series of events from **square feet** into **square meters**:
1. In your Pipeline, open the required [Action](/the-workspace/pipelines/actions.md) configuration and select the input **Field**.
2. In the **Operation** field, choose **Convert area**.
3. Set **Input units** to `Square foot (sq ft)`.
4. Set **Output units** to `Square metre (sq m)`.
5. Give your **Output field** a name and click **Save**. The values in your input field will be transformed. For example:
```
Input data - "5000"
Input units - "Square foot (sq ft)"
Output units - "Square metre (sq m)"
Output data - "464.515215"
```
{% hint style="info" %}
You can try out operations with specific values using the **Input** field above the operation. You can enter the value in the example above and check the result in the **Output** field.
{% endhint %}
