# Step 2: Create a Calculated Channel

## Overview

To better understand how Calculated Channels work, let's create one using the temperature Channel from the LEO dataset in Tutorial 1. Specifically, we will create a Calculated Channel that converts the **camera\_1.temperature** Channel from Celsius to Fahrenheit.

## Create a Calculated Channel

1. In **Sift's** homepage, click the <Icon icon="waves-sine" /> **Calculated Channels** tab.
2. Click **New Calculated Channel**.
3. In the **Calculated Channel name** box, enter the following:
   ```
   fl_tutorial_6_calculated_channel
   ```
4. Replace `fl` (in `fl_tutorial_6_calculated_channel`) with your initials.
5. In the **Asset** list, select the Asset you created in Tutorial 1.
6. In the **Input Channels** list, select the following Channel:
   * **camera\_1.temperature**
7. In the **Query (expression)** box, enter the following:
   ```
   ($1 * 9/5) + 32
   ```

Expressions define how a Calculated Channel derives its values from input data. They can reference input Channels (for example, `$1`), other Calculated Channels, constants, operators, and built-in functions. Before saving, you can preview the output to verify the expression behaves as expected.

8. Click the **Select Run(s) to preview** tile.
9. In the **Runs** table, click the name of the Run created in Tutorial 1.
10. Click **Preview 1 Runs**.
11. Click **Save**.
