The SI unit of force is Newton, but sometimes it is more intuitive to
measure force (e.g. the thrust of a jet engine) in kiloponds (or pounds
of force for you anglophones).

So what? There's still 2e20 joules worth of gravity's energy, whereas
if just 0.1% of that force as energy gets applied to a given terrestrial
m2 is worth 391 joules.
