How to calculate explosions from weird angles?

[Naito-desu]

So I got a few images here, but I don't know where to start in calculating the size of the explosion. This is the largest one done so far, but it's done from a weird angle and I'm not experienced with angular size calculation

You'd need more screenshots of them fighting. Otherwise we can't do pixelscaling. Also try to find an example of one of the characters near one of the roofs so we can get a scale

or at least find an image of one of the roofs on a buildings so we can use floors for measure

actually now that i look closer the first shot may work
just get a shot of the insides of such houses and we can get a size of a floor, then we can get the size of a roof

Simply calculate the size of the ground where they are

though tbh i don't think you'll be able to use it since we only accept what's shown in the manga

yeah but to calc the size of the ground you need to compare it to sth, not to mention that the explosion is bigger than they are

Don't see this getting far though. Eyballing it, assuming that the roof is around 9 meters since its about 3 floors tall, the explosion yield is like 0.0073235737 tons which is nothing

There's explosions in the manga, there's just no wide shots or shots with more context for the explosion size.

I'm pretty sure that we accept Rengoku's third form from the anime which doesn't appear in the manga, so that isn't entirely true.
