Are AWS network charges in GB (gigabytes) or GiB (gibibytes)


- 1 GB = 1000 MB (1000 bytes ^ 3)

- 1 GiB = 1073 MB (1024 bytes ^ 3)

The docs don't seem to explicitly mention it. They just say GB.

But AWS has been known to use GB for simplicity in docs - as in https://aws.amazon.com/s3/pricing/.

I have been tearing my hair out trying to get to the bottom of this. It starts to matter when making cost calculations are large scale.

> Amazon S3 storage usage is calculated in binary gigabytes (GB), where 1 GB is 2^30 bytes. This unit of measurement is also known as a gibibyte (GiB), defined by the International Electrotechnical Commission (IEC). Similarly, 1 TB is 2^40 bytes, i.e. 1024 GBs.

Just scroll down a bit. It's in the "S3 Pricing Details" section of that page you linked to: (https://aws.amazon.com/s3/pricing/#:~:text=Amazon%20S3%20sto....)
