Steven Universe - Strong in the real way

Sardonyx swings her hammer casually, which is an incredible feat in itself. To get the volume of the hammer, we'll be scaling from Steven using the average height of a 12 year old boy (that being 58 inches, or 1.4732m).

62 pixels = 1.4732m
1 pixel = 1.4732m/62 = 0.0237612903m
0.0237612903m X 510 = 12.1182581m
0.0237612903m X 264 = 6.27298064m
0.0237612903m X 298 = 7.08086451m
0.0237612903m X 74 = 1.75833548m
1.75833548m/2 = 0.87916774m
0.0237612903m X 256 = 6.08289032m
0.0237612903m X 320 = 7.6036129m

340 pixels = 7.6036129m
1 pixel = 7.6036129m/340 = 0.0223635674m
0.0223635674m X 268 = 5.99343606m

Now we have all the components, let's get the volume of the hammer. Both fists as rectangles and the middle part as a cylinder.

V = lhw
= 7.6036129 X 6.27298064 X 5.99343606
= 285.870816771 X 2
= 571.741633542m^3

V = πr^2h
= π X 0.87916774^2 X 6.08289032
= 14.770777157m^3

V = 571.741633542 + 14.770777157
= 586.512410699m^3

For our mass, we'll go with a low end of aluminium, a mid end of titanium and a high end of steel, which weigh 2600kg/m^3, 4500kg/m^3 & 7850kg/m^3 respectively.

(low end)
M = 586.512410699 X 2600
= 1524932.26782kg

(mid end)
M = 586.512410699 X 4500
= 2639305.84815kg

(high end)
M = 586.512410699 X 7850
= 4604122.42399kg

She swings it in a full arc, so we'll get the distance as the circumference of a circle (from where she's holding it).

C = 2πr
= 2 X π X 7.08086451
= 44.4903838514m
Spoiler:

0.19 seconds.

Let's get our energy, shall we?

(low end)
KE = (0.5)mv^2
= (0.5) X 1524932.26782 X 177.961535^2
= 24147537254.4 joules
= 5.771399917399618 tons of TNT

(mid end)
KE = (0.5)mv^2
= (0.5) X 2639305.84815 X 177.961535^2
= 41793814478.8 joules
= 9.9889613955066920425 tons of TNT

(high end)
KE = (0.5)mv^2
= (0.5) X 4604122.42399 X 177.961535^2
= 72906987479.6 joules
= 17.42518821214149 tons of TNT

Final Results
Sardonyx swings her hammer (low end) = 5.771 tons of TNT
Sardonyx swings her hammer (mid end) = 9.989 tons of TNT
Sardonyx swings her hammer (high end) = 17.425 tons of TNT
