| Consistency | Description | IC | Unconfined compressive strength (qu) (kN/mm2) |
| Liquid | Liquid | < 0 | N.A. |
| Plastic | Very Soft | 0 - 0.25 | < 25 |
| Soft | 0.25 - 0.5 | 25 - 50 | |
| Medium stiff | 0.5 - 0.75 | 50 -100 | |
| Stiff | 0.75 -1.00 | 100 - 200 | |
| Semi | Very Stiff or Hard | > 1 | 200 - 400 |
| Solid | Hard or very hard | > 1 | > 400 |
Additional Information Consistency Index
It is defined as the ratio of difference between the liquid limit and natural water content of the soil to the plasticity index.
