Comparison of Durometer Hardness Scales

This chart is an approximate comparison of Shore and Asker durometer scales. It is not a conversion chart.
When selecting a scale for your material aim for measurements of 50.
Measurements below 10 and above 90 are not recommended.
Also consider the indentor shape and its effect on the material: cone, truncated cone or hemispherical.
