BQ25150: How to read battery temperature by using TS

Part Number: BQ25150

Hello,

I want to read temperature of battery(Li-Ion),by using TS.

From data sheet (TI BQ25150) , I got info about Vts.

But there is no info about conversion of Vts to degree C. How to convert from Vts to degree C.

Is there is another way to read temperature of battery except ADCIN.

Thanks
