Accumulated interference power for PRB

Hi, according to vendor doc, the following parameters

pmRadioRecInterferencePwrPrb1
The accumulated interference power for PRB1
Unit: mW * 2^(-44)
Scanner: Not included in any predefined scanner
Condition: Samples summed over the measurement period. Measurements are averaged over receive antennas. One sample for each PRB per 40ms.
Counter type: CC/SUM
Counter is reset after measurement period: Yes

How can I convert them to dBm?

If I apply directly factor 2^(-44) the values make no sense.

For example, for CELL_1 the value of PMRADIORECINTERFERENCEPWRPRB1 for DAY_1 is

166744963

If factor 2^(-44) is applied the mW value is
9.47835E-06

and in dBm the value is -50.23 which makes no sense.

Thanks in advance.
