750 Watts to Joules
Watts measure power and joules measure energy, so the answer depends on time. Here is what a 750 W device uses over each period.
750 J per second
Because 1 watt = 1 joule per second, 750 W delivers 750 J every second it runs.
- Per minute
- 45,000 J
- Per hour
- 2,700,000 J
- Per hour (kWh)
- 0.75 kWh
- Per day
- 64,800,000 J
750 watts to joules, explained
A watt is a rate: one watt means one joule of energy is used every second. So 750 watts means 750 joules per second. To get a total number of joules you multiply by how long the power runs.
For example, a 750 W device left on for one hour uses 750 × 3,600 = 2,700,000 J. Over a full day it uses 64,800,000 J. On an electricity bill, one hour of use is 0.75 kWh.
750 W draws about the same power as 13 old-style 60 W incandescent bulbs running at once. One hour at 750 W consumes 0.75 kWh of electricity — about $0.112 at a US average residential rate of $0.15 per kWh.
joules = 750 W × time in seconds12-cup drip coffee maker (750 W)
A standard drip coffee machine consumes about 750 watts to heat water and maintain the hot plate.

FAQ: 750 watts
How many joules is 750 watts?
750 watts is not a fixed number of joules on its own — watts measure power and joules measure energy, so you need a time. A 750 W device uses 750 J every second, 2,700,000 J over one hour (0.75 kWh).
How do you convert 750 watts to joules?
Multiply 750 by the number of seconds the power runs. Joules = 750 × time in seconds. For one hour that is 750 × 3,600 = 2,700,000 J.
How much energy does a 750 W device use per hour?
A 750 W device running for one hour uses 2,700,000 J, which is 0.75 kWh on an electricity bill.
