# 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>
