Why is Raspberry Pi 3B / 3B+'s CPU temperature precision 0.538°C?

While monitoring CPU temperature from /sys/class/thermal/thermal_zone0/temp, I noticed that the minimal step is exactly 0.538°C. This is the same on both Pi 3 B and Pi 3 B+, and I suppose that it applies to Pi 3 A+. Why is it this value?

Monitor temperature in fahrenheit

Using raspbian right now. I know you can add the temperature plugin to the panel, but it only shows Celsius. How can this be changed? Or is there another program I can use that will work better?
