Wireshark values of Signal level and SNR different from terminal (layer 1,2 &3) output values

I have been noticing from quite a while that the values of Signal level and SNR embedded in GSM header (GSMTAP) in wireshark (b/w 0-255) are different from that visible on the terminal while layer 1 and layer 2 & 3 are operating (something like -60 dBm and 60 dB respectively). Can anybody plz explain why is that difference if both these values represent the same meaning? Is that due to different definations of int8_t and int in GSMTAP.h and gsm48_rr.c respectively. If yes how to convert these values to dBm as shown in terminal?
