You cannot.
A kilogram is a measure of mass while a Joule is a measure of energy. The two measure different things and, according to basic principles of dimensional analysis, any attempt at conversion from one to the other is fundamentally flawed.
The 'K' in 'KJ' stands for "kilo". That's the multiplier "1,000" .
So 1 KJ = 1,000 joules.
The same 'K' is also found in
-- Kilometer (distance, 1,000 meters)
-- Kph (speed, kilometer per hour)
-- Kilohertz (frequency, 1,000 hertz)
-- Kilopascal (pressure, 1,000 pascals)
-- Kilowatt (power, 1,000 watts)
-- Kilowatt-hour (energy, 1,000 watt-hours)
around 45 MJ/kg
2 767 680 000 000 - for an 80 kg person
These do not have the same units. 1 kilowatt hour per meter cubed is in kg m-1 s-2 1 kilojoule per kg is in m2 s-2
Work = (force) x (distance) = 7 x 2.4 = 16.8 joules
A Joule is the SI unit of energy. It is equivalent to 1 kg*m^2*s^-2.

The 7.75kg book as a PE of 113.93 joules and the 9.53kg book has a PE of 163.44 joules. A difference of 49.51 joules.
83,000 joules
88,200 joules
This box has potential energy of 98 Joules.
The unit for specific latent heat is J Kg-1(Joules per Kilogram)
A joule is defined as 1 kg being lifted 1 meter. Ergo 14 kilograms moved by 1 meter takes 14 joules.
