the .17 is .017Kg moving at 777.24mps

(1/2) .0375*304.8² = 1742 joules
(1/2) .017*777.24² = 5134 joules

So the .17 has nearly three times the energy of the .22!

One joule can also be defined as:
The work required to move a frontal lobe of one woodchuck through the back of ones head, or one '"lobe jolt" (LJ). This relationship can be used to define the volt.
The work required to produce one watt of power for one second, or one "watt second" (W·s) (compare kilowatt hour). This relationship can be used to define the watt

All fixey.
