200 Joules to Watts

Joules measure energy and watts measure power, so the answer depends on time. Here is the wattage required to expend 200 J over each period.

200 joules equals

200 W (over 1 second)

Because 1 watt = 1 joule per second, expending 200 J in exactly 1 second requires a power of 200 W.

3.33333 W
Over 1 hour
0.0555556 W
Over 1 day

200 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 200 joules equals, you must know how fast that energy is used.

For example, releasing 200 J over one hour (3,600 seconds) requires 200 ÷ 3,600 = 0.0555556 W. Releasing it slowly over a full day only requires 0.00231481 W.

watts = 200 J ÷ time in seconds

Frequently asked questions

How many watts is 200 joules?

200 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, 200 J over 1 second is 200 W.

How do you convert 200 joules to watts?

Divide the 200 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 200 ÷ 3,600 = 0.0555556 W.
