MOSFET threshold voltage calculation across temperature using normalised values
You cannot get absolute values of VGS(th) from normalized data.
From the data sheet:



The variation of VGS(th) with temperature tells you the you can expect a drop in VGs(th) of 10% from 25 -125 degC. That gives you 0.1% per degC 

It tells you little about an individual device VGS(th) since the range is from 0.8 min to 2.4 V max.

To be sure you are putting devices with an absolute range of VGS(th) over temperature you'd need to buy binned devices, which cost more.
