Memory capacity conversion (GB vs. GiB)

The capacity calculation units in Memory and Available memory^[1] used in Container Compute Service, High-performance Computing, and Virtual Compute Service (GPU instance series) are different. Refer to the following for the differences and conversion formulas.

Unit description

• Memory: uses GB (Gigabytes) for measuring the capacity. 1 GB = 10⁹ bytes.
• Available memory: uses GiB (Gibibyte) for measuring the capacity. 1 GiB = 2³⁰ bytes.

Value conversion

Conversion formula: 1 GB ≈ 0.93 GiB

Please refer to the table^[2] below for the conversion of Memory and Available Memory for all service specifications:
