With this tool, you can calculate many fiat (government issued) currency amounts into O_byte native currency amounts, including different O_byte own amounts (GByte, MByte, KByte and Byte).

For example, you can send 5 US dollars (or 5 euros) worth of Bytes to other users by simply filling some fields and clicking the "send with O_byte wallet" button, which would automatically open your O_byte wallet app waiting to be confirmed to send right amount of Bytes.

It could also be used to request $5 worth of Bytes by sending a link of automatically filled form to somebody or showing somebody a QR code that gets generated when the form is correctly filled (O_byte wallet app has QR code reader built in).
