# Convert a UOM
When buyers send you an event, they request goods and services in various [UOMs](/glossary/glossary/unit-of-measure-overview/uoms.md) (units of measure). However, you may only supply the item or service in a different UOM. To ensure you provide an accurate price, use the convert option to enter your response in your UOM. When the buyer views your response, they will see the quantity and price in their originally requested UOM; additionally, the response will include a warning with details about the conversion.
**UOM conversion example**: If a buyer requested 100 pens (each), but you only sell pens in packs of 20. You can enter that each pack is equal to 20 pens. Fairmarkit will convert the price, letting the buyer know they need to purchase 5 packs at your quoted price.
### Convert a UOM on a line

Enter the following information, defining how the new UOM relates to the requested UOM:

* **Amount**: Enter the quantity of the requested UOM included in the New UOM.
{% endstep %}
{% step %}
Click **Change**.\
Fairmarkit updates the QTY and UOM and calculates the unit price based on the new UOM. When the buyer views your response, they will see the quantity and price in their originally requested UOM; additionally, the response will include a warning with details about the conversion.

{% endstepper %}

## Querying This Documentation
If you need additional information that is not directly available in this page, you can query the documentation by asking a question.
Perform an HTTP GET request on the following URL with the `ask` and `goal` query parameters:
```
GET https://docs.fairmarkit.com/suppliers/suppliers/events/respond-to-an-event/convert-a-uom.md?ask=&goal=
```
`ask` is the immediate question: it should be specific, self-contained, and written in natural language.
`goal` is what the user is ultimately trying to achieve, the reason they need the answer. Sharing it helps GitBook give you a better, more relevant answer. A goal is most helpful when it describes the outcome the user wants rather than restating the question. For example, with `ask=how do I create an API token`, a goal like `automate deployments from our CI pipeline` lets GitBook tailor the answer to that use case.
The response will contain a direct answer to the question and relevant excerpts and sources from the documentation.
Use this mechanism when the answer is not explicitly present in the current page, you need clarification or additional context, or you want to retrieve related documentation sections.
