# M.1 to cc size mapping
General mapping of M.1 to cc cluster sizes.
The following table provides a general mapping of M.1 to cc cluster sizes:


**M.1 to cc:**

| M.1 Size | cc Size |
| --- | --- |
| <strong>M.1-nano</strong> | 25cc |
| <strong>M.1-nano</strong> | 50cc |
| <strong>M.1-micro</strong> | 100cc |
| <strong>M.1-xsmall</strong> | 200cc |
| <strong>M.1-small</strong> | 300cc or 400cc |
| <strong>M.1-medium</strong> | 600cc or 800cc |
| <strong>M.1-large</strong> | 800cc |
| <strong>M.1-1.5xlarge</strong> | 1200cc or 1600cc |
| <strong>M.1-2xlarge</strong> | 1600cc |
| <strong>M.1-3xlarge</strong> | 3200cc |
| <strong>M.1-4xlarge</strong> | 3200cc |
| <strong>M.1-8xlarge</strong> | 3200cc |
| <strong>M.1-16xlarge</strong> | 6400cc |
| <strong>M.1-32xlarge</strong> | 128C |
| <strong>M.1-64xlarge</strong> | 256C |
| <strong>M.1-128xlarge</strong> | 512C |


**cc to M.1:**

| cc Size | M.1 Size |
| --- | --- |
| 25cc | <strong>M.1-nano</strong> |
| 50cc | <strong>M.1-nano</strong> |
| 100cc | <strong>M.1-micro</strong> |
| 200cc | <strong>M.1-xsmall</strong> |
| 300cc | <strong>M.1-small</strong> |
| 400cc | <strong>M.1-small</strong> |
| 600cc | <strong>M.1-medium</strong> |
| 800cc | <strong>M.1-large</strong> or <strong>M.1-medium</strong> |
| 1200cc | <strong>M.1-1.5xlarge</strong> |
| 1600cc | <strong>M.1-2xlarge</strong> or <strong>M.1-1.5xlarge</strong> |
| 3200cc | <strong>M.1-8xlarge</strong> or <strong>M.1-4xlarge</strong> or <strong>M.1-3xlarge</strong> |
| 6400cc | <strong>M.1-16xlarge</strong> |
| 128C | <strong>M.1-32xlarge</strong> |
| 256C | <strong>M.1-64xlarge</strong> |
| 512C | <strong>M.1-128xlarge</strong> |




Some sizes have multiple mappings. When converting between M.1 and cc sizing, we
recommend choosing the larger mapping size first.
