WMI types conversion issue

I want to get ram slots memory and convert it to GB. I use WMI, Win32_PhysicalMemory class with property Capacity.

Code:

QString userRAMCapacity = QString::fromWCharArray(ramCapacity.bstrVal);

When using Qt function - 

QString::fromWCharArray(ramCapacity.bstrVal);

I get proper ram slots memory capacity in bytes, but I can't convert it to GB. I tried to use another function - 

QString::number(ramCapacity.uintVal),

it works but display the wrong memory amount. Please help to fix this issue. Thanks in advance.

QString has toInt() method that you would need to apply before doing any math:

auto result = QString::fromWCharArray(ramCapacity.bstrVal). toLongLong() / (1024) / (1024) / (1024);
