# Unit of Measurement

The units of measurement for resources on the vStorage system are described in the table below:

<table data-view="cards" data-full-width="true"><thead><tr><th></th><th></th><th></th><th></th><th></th></tr></thead><tbody><tr><td><strong>Resource</strong></td><td><strong>Definition</strong></td><td><strong>Unit</strong></td><td><strong>Conversion Rate</strong></td><td><strong>Conversion Details</strong></td></tr><tr><td>Quota</td><td>Quota is a maximum storage capacity limit set at the time of initializing a Project. For each storage package, we provide a minimum and maximum storage capacity that you can choose based on your actual needs. Changing the Quota is seamless and does not impact the connected services and storage on the upgraded Project.</td><td>byte</td><td>1024</td><td><ul><li>1 KB (Kilobyte) = 1024 byte</li><li>1 MB (Megabyte) = 1024^2 byte</li><li>1 GB (Gigabyte) = 1024^3 byte</li><li>1 TB (Terabyte) = 1024^4 byte</li><li>1 PB (Petabyte) = 1024^5 byte</li><li>1 EB (Exabyte) = 1024^6 byte</li><li>1 ZB (Zettabyte) = 1024^7 byte</li><li>1 YB (Yottabyte) = 1024^8 byte</li><li>...</li></ul></td></tr><tr><td>Usage</td><td>Usage is the actual amount of data that has been uploaded and stored on vStorage.</td><td>byte</td><td>1024</td><td><ul><li>1 KB (Kilobyte) = 1024 byte</li><li>1 MB (Megabyte) = 1024^2 byte</li><li>1 GB (Gigabyte) = 1024^3 byte</li><li>1 TB (Terabyte) = 1024^4 byte</li><li>1 PB (Petabyte) = 1024^5 byte</li><li>1 EB (Exabyte) = 1024^6 byte</li><li>1 ZB (Zettabyte) = 1024^7 byte</li><li>1 YB (Yottabyte) = 1024^8 byte</li><li>...</li></ul></td></tr><tr><td>Traffic</td><td>Traffic is a metric based on the data volume (in GB) that an object retrieves from storage (Get/Down).</td><td>byte</td><td>1000</td><td><ul><li>1 KB (Kilobyte) = 1000 byte</li><li>1 MB (Megabyte) = 1000^2 byte</li><li>1 GB (Gigabyte) = 1000^3 byte</li><li>1 TB (Terabyte) = 1000^4 byte</li><li>1 PB (Petabyte) = 1000^5 byte</li><li>1 EB (Exabyte) = 1000^6 byte</li><li>1 ZB (Zettabyte) = 1000^7 byte</li><li>1 YB (Yottabyte) = 1000^8 byte</li><li>...</li></ul></td></tr><tr><td>Request</td><td>Request is a communication sent to a web server or machine from a client (typically a web browser) to receive and view available information. A request includes details such as the URL, method (GET or POST), headers, cookies, and any attached data.</td><td>number</td><td>N/A</td><td>N/A</td></tr></tbody></table>

# Agent Instructions: Querying This Documentation

If you need additional information that is not directly available in this page, you can query the documentation dynamically by asking a question.

Perform an HTTP GET request on the current page URL with the `ask` query parameter:

```
GET https://docs.vngcloud.vn/vng-cloud-document/vstorage/object-storage/what-is-vstorage/unit-of-measurement.md?ask=<question>
```

The question should be specific, self-contained, and written in natural language.
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.
