One Joule is one Newton-Meter, (Joule = Newton times Meter), so 10000 Joule equals 10 Newton-Kilometers (N*km). 10000*J/N = 10 km
Answer
You might as well be asking how many millimetres there are in kilowatt! Your question is meaningless! A kilometre is used to measure length, whereas the joule is used to measure energy. The original answer is nonsense.

How many joules are there in a kilojoule?
A Joule is a Watt-second (or W=J/s). Therefore, 3.5 kWh = 3.5*3600 kWs = 3.5*3600*1000 W-s = 12.6 million Joules
How long could 90 Js of energy light a 40 Watt light balb.?
To calculate this, we first need to convert the energy from joules to watt-hours. 90 joules is equal to 0.025 watt-hours. Therefore, with 0.025 watt-hours of energy, a 40 watt light bulb would last for approximately 0.000625 hours or 0.0375 minutes.
How many watt hours is 60 watt?
Running a power of 60 watts for one hour uses 60 watt-hours of energy. If you run it for two hours, that would be 120 watt-hours. Running a 60 watt appliance for 16 hours and 20 minutes is 1000 watt-hours, or 1 kWh, also called one Unit.
Calculate number of joules in 1kwh?
1 Watt = 1 Joule/second 1 kilowatt = 1000 Watts = 1000 Joules/second 1 hour = 60 minutes = 3600 seconds 1 kWh = 1000 (Joules/second) * 3600 (seconds) = 3,600,000 Joules = 3.6 MJoules
How many watts in 1 kilowatt?
Killo = 1000. There are 1000 watts in 1 kw.
