I found this feat from another thread, but it was forgotten about I guess. The anime version of this feat was actually calculated but we shouldn't be using the anime version since the manga is more canon.
According to the official databooks, the meteor that was going to fall on City Z was 200 meters in diameter. Metal Knight launches his missiles at the meteor and the explosion is massive. The moment before the detonation of the missiles, we're able to see the size of the meteor from Genos' perspective, and from that same distance, we get to see the explosion.
As a lowball, the explosion's length is 20 times the size of the meteor. The meteor was falling in this angle so using 200 meters to get the explosion size should be fairly accurate.
We could estimate that the explosion is roughly 4.5 km in length. According to this site , a nuclear explosion with a diameter of 5 km would be roughly 45 megatons.
This is an unbelievably rough estimation of the power of the explosion. If anyone can actually calc it, that would be much appreciated. But regardless, an explosion that is 4.5 km in length could possibly warrant an upgrade.
