This is something I've wanted to tackle for a while now so...
Scaling 1:
Toriko = 220cm = 658px
Sitting Height = Approx 353px = 118cm
Scaling 1:
Toriko = 17.7px = 1.18m
Sky Vegetable Leaf Size = Approx. 9.2m = 137.8px
Scaling 2:
Leaf = Approx 9.2 = 25.6px
Distance from Toriko to Clouds = 88px = 31.6m
Scaling 3:
Toriko = 12.8px = 2.2m
Distance from Lightning Striking = 85.9px =14.8m
Low-End:
((14.8)*(100000))/31.6
=
46835.443038 m/s = Mach 136.5
Average:
((14.8)*(440000)/31.6
=
110748.29932 m/s = Mach 600.8
High-End:
((14.8)*(1400000))/31.6
655696.202532 m/s = Mach 1911.7
I'd side between the Low-End and Average though
