Calibrate Landsat 8 image to BT (Brightness Temperature) in Kelvin by SNAP ESA

Hi,
I wish to calibrate Landsat 8 TIRS band 1 image to BT (Brightness Temperature) in Kelvin. I tried using ENVI but an error occurs importing the MTL file (containing matadata). Is there any provision for this calibration in SNAP ESA? I tried checking on the internet but I am not able to find.

Yes, this is possible to do in SNAP using bandmath; Following is good example you could follow,
