1,440 Joules to Watts

Joules measure energy and watts measure power, so the answer depends on time. Here is the wattage required to expend 1440 J over each period.

1440 joules equals

1,440 W (over 1 second)

Because 1 watt = 1 joule per second, expending 1440 J in exactly 1 second requires a power of 1,440 W.

1440 joules to watts, explained

A watt is a rate of energy transfer: one watt means one joule of energy is transferred every second. Therefore, to find out how many watts 1440 joules equals, you must know how fast that energy is used.

For example, releasing 1440 J over one hour (3,600 seconds) requires 1440 ÷ 3,600 = 0.4 W. Releasing it slowly over a full day only requires 0.0166667 W.

watts = 1440 J ÷ time in seconds

Frequently asked questions

How many watts is 1440 joules?

1440 joules does not equal a fixed number of watts. Joules measure energy and watts measure power. To find watts, you must divide the joules by the time in seconds. For example, 1440 J over 1 second is 1,440 W.

How do you convert 1440 joules to watts?

Divide the 1440 joules by the number of seconds the energy is released over. Power (W) = Energy (J) ÷ Time (s). If the time is 1 hour (3,600 seconds), it is 1440 ÷ 3,600 = 0.4 W.
