Kinetic energy is given in units of energy typically watts in English units or Joules in SI units.
Ft-lbs are definitely not the correct unit.
I like SI because it's more logical so converting,

So then,

Word of warning, don't use online calculators for simple calculations.
They might not yield the correct answer.
