Dielectric strength is the strongest electric field that a material can withstand before breaking down.
On the other hand, the dielectric constant of a material is the ratio of a capacitor’s capacitance filled with that material, compared to a capacitor filled with vacuum.
These 2 quantities have different units, and a look at table 24.2 shows that there is no simple relationship between the 2.
