700 kilowatt is equivalent to 2,520,000,000 joules when converted by multiplying with the number of seconds in an hour.
This conversion comes from the relationship between power and energy: power in kilowatts multiplied by time in seconds gives energy in joules. Since 1 kilowatt equals 1000 watts and 1 watt equals 1 joule per second, converting 700 kilowatts over one hour yields the result.

Conversion Formula
The formula to convert kilowatt to joules depends on the time period over which power is applied. Power (in watts) multiplied by time (in seconds) gives energy (in joules). Since 1 kilowatt = 1000 watts, energy can be found by:
Energy (J) = Power (kW) × 1000 (W/kW) × Time (s)
For example, converting 700 kilowatt-hours to joules for a 1-hour period:
- Convert kilowatts to watts: 700 kW × 1000 = 700,000 W
- Calculate seconds in 1 hour: 1 hour × 3600 s/hour = 3600 s
- Multiply power by time: 700,000 W × 3600 s = 2,520,000,000 J
Conversion Example
- Convert 500 kilowatt-hours to joules:
- 500 kW × 1000 = 500,000 W
- 1 hour × 3600 seconds = 3600 s
- Energy = 500,000 W × 3600 s = 1,800,000,000 J
- Convert 350 kilowatt-hours to joules:
- 350 kW × 1000 = 350,000 W
- 1 hour = 3600 s
- Energy = 350,000 W × 3600 s = 1,260,000,000 J
- Convert 1000 kilowatt-hours to joules:
- 1000 kW × 1000 = 1,000,000 W
- 1 hour = 3600 s
- Energy = 1,000,000 W × 3600 s = 3,600,000,000 J

Conversion Definitions
Kilowatt: A kilowatt is a unit of power equal to 1,000 watts. It measures the rate of energy transfer or usage over time. One kilowatt represents the consumption or generation of 1,000 joules per second, often used in electrical systems to describe power output or consumption.
Joules: Joule is the SI unit of energy, representing the amount of work done when one watt of power is applied for one second. It quantifies energy, heat, or work in mechanical, electrical, or other physical processes. One joule equals one newton meter of work or one watt-second.
Conversion FAQs
Can you convert kilowatt to joules without considering time?
No, you cannot. Kilowatt measures power, which is energy per unit time. To convert power to energy in joules, you must multiply by the time duration in seconds. Without time, the conversion is incomplete and meaningless.
Why multiply kilowatts by 1000 and 3600 in the conversion?
Kilowatt is 1,000 watts, so multiplying by 1000 converts kilowatts to watts. Since watts equal joules per second, multiplying by 3600 (seconds in an hour) gives total energy in joules over one hour. Both factors convert units properly for energy calculation.
How do I convert kilowatt to joules for durations other than one hour?
Use the formula Energy (J) = Power (kW) × 1000 × Time (seconds). Convert the time period into seconds, then multiply by power in watts. This gives joules for any duration, not just one hour.
Is 700 kilowatt equal to 700 joules?
No. Kilowatt is a power unit indicating rate of energy use, while joule measures total energy. Without multiplying by time, they cannot be equated. 700 kilowatt over a time period will produce energy measured in joules.
What does it mean if I see 700 kilowatt-hours instead of kilowatts?
Kilowatt-hour measures energy, not power. It represents the energy used by 700 kilowatts running for one hour. To convert kilowatt-hours to joules, multiply by 3,600,000 (3600 seconds × 1000 watts). Kilowatt alone needs time to be converted to joules.
