| Specific Gravity | Dimensionless ratio, do not convert. Same
value as density in gm/cc (without dimensions). |
| Melt Flow Rate | Always in grams per 10 minutes...do not convert. |
| Elongation | Always % strain, which is dimensionless, do not convert. |
| Mold Shrinkage | Dimensionless; inches/inch, yards/yard or
cms/cm all have the same numeric value. |
| Hardness | Both Shore D and Rockwell R are indexed scales...do not convert. |
| RTI | A UL thermal index, always given in degrees Celsius, do not convert. |
