Realcalc has an excellent RPN mode (enabled through Calculator Type in Settings). I’ve used it for the last six years or so (technically, in the premium version of the app).

I think the median average temperature is around 2,200°C.

The Earth has a radius of 6,371km, giving a volume of 1.08e13km^3.

A sphere of half this volume would have a radius of 5,057km. Within the Earth, this sphere would sit at a depth of 6,371 - 5,057 = 1,314km.

From this chart, the temperature at that depth is around 2,200°C, so half the volume of the Earth has a temperature above that, and half a temperature below it.

Holy contrived punchline, Batman!
