# Process Variables

There are settings that need to be configured across our TilliT account to create a vocabulary for our digital factory. As seen in [Definitions](/tillit/getting-started/definitions.md), Process Variables play an important role and the configuration section is where you will set this.

The Process Variable represents the measured value or parameter of a particular part of a process that is being monitored and controlled. List the **relevant process variables** and consider how they are stored and measured, as well as any recipe settings, limits, design parameters, and other relevant characteristics. Next, think about what their **Unit of Measure** is e.g. litres, degrees Celsius, carton etc.

For example: temperature in degrees Celsius and batch size in litres.
