# base-2 (Rather than base-10) for Billing Calculations

Wasabi uses base-2 (sometimes also referred to as base-1024) rather than base-10 (sometimes also referred to as base-1000) in all billing-related usage measurements, billing dashboard displays, and billing invoices. This means that:

- 1 GB = 1,073,741,824 bytes (1024 bytes * 1024 * 1024)
- 1 TB = 1024 * 1 GB = 1,099,511,627,776 bytes
- 1 PB = 1024 * 1 TB = 1,125,899,906,842,620 bytes

Although the [IEC](https://en.wikipedia.org/wiki/Gibibyte) indicates that the use of base-2 calculations should result in the use of terms like GiB, TiB, and PiB (rather than GB, TB, and PB), Wasabi follows the [AWS convention](https://forums.aws.amazon.com/thread.jspa?threadID=151161) of using the GB, TB, and PB terms even when using base-2 calculations (many other vendors in the storage industry do the same).
