# How many watts in a joule?

A joule is a quantity of energy, whereas a watt is a rate of energy flow, so they are not the same type of quantity. A watt is the power produced by a flow of energy at a rate of 1 joule per second.

## Related Questions Watts are units of power. Joules are units of energy. They are not the same. One watt is one joule per second. Power. In SI, energy is measured in Joule, and power is measured to watts (= Joule per second).Power. In SI, energy is measured in Joule, and power is measured to watts (= Joule per second).Power. In SI, energy is measured in Joule, and power is measured to watts (= Joule per second).Power. In SI, energy is measured in Joule, and power is measured to watts (= Joule per second). A joule is a joule, whether it be electrical energy or light energy - although commonly, lamps are not 100% efficient.On the other hand, you can't convert joules directly to watts. Watts means joules per second (joules / second), or equivalently, joules is watts times seconds.A joule is a joule, whether it be electrical energy or light energy - although commonly, lamps are not 100% efficient.On the other hand, you can't convert joules directly to watts.

Watts means joules per second (joules / second), or equivalently, joules is watts times seconds. Watts are measured in Joules and a joule is work divided by time. (w/sec) The relationship is between watts, seconds, and joule. Watt is the unit for power, joule for energy. Watt = joule / second. A watt is a unit of power. 1 watt = 1 joule/second; that is, if somebody consumes 1 watt, it consumes 1 joule of energy every second. Or if there is a transfer of 1 watt, 1 joule of energy is transferred every second. 1000 watts (1 kW), of course, is simply 1000 times as much (1000 joule/second). 1 Watt = 1 Joule / 1 secEssentially, watts are how many joules you consume in a second.source: http://answers.yahoo.com/question/index?qid=20070612222659AAEx9un  More watts = more energy use. The unit of energy is the Joule; Watt is a unit of power, and means an energy use of 1 Joule/second. Kilo is a prefix which means 1,000. So, the answer is 1000 watts. You can't convert them directly, because they measure different things. The unit for energy is the Joule. Power means how fast energy is transferred; it is measured in Joules/second, also called Watts. Power is measured in watts. A watt is one joule per second. One joule per second is one volt-ampere per second when the power factor is 1.0. Commonly, when dealing with power plants, power is measured in kilowatts (1,000 watts), megawatts (1,000,000 watts), or gigawatts (1,000,000,000 watts). in electronics, there is a term of Watt Hours used in power bills and things. watts itself is a unit derived by 1 joule per second. in order to get watt hours (which is just 1 joule per hour) you multiply your watts (joule/second) by 360 (60 seconds in a minute multiplied by 60 minutes in an hour). that will then give you units of joules/hour there are zero watts in a hertz. Watts is a measure of power. One Watt equals one Joule per second. A hertz is a frequency or in actuality the inverse of a fequency 1/f and is ussually represented in cylces per second. If it is 1000 watts then it produces a 1000 watts. A watt is 1 joule/sec. A Watt is power. A Joule is Energy. A Joule is a Watt X Seconds. Watts are units of Power, whereas Joules are units of Energy. Power is Energy in accordance to time: P = E/t . So One Watt of Power is equal to one Joule per second. P=E/t 1 Watt = 1 Joule/ 1 second 1 joule = 1 N &times; m (1 newton-metro) = 1 W &times; s (watts-segundo) A kilowatt is 1000 watts, and 1 watt is 1 joule per second A watt is the SI unit of power. It's equivalent to one joule per second.  Joule is a unit of energy, watt is a unit of power. Power is energy per time unit. In a way, those are incompatible units, but if you know in what time you spend a certain amount of Joule, you can convert to Watt, and vice versa. For example, if you use 200 Joule in 2 seconds, that is 200/2 = 100 Joule/second, or 100 Watts. Or, if a light-bulb uses 35 Watts, that is 35 Joules every second, so in an hour it will use 35 x 3600 = 126000 Joules, or 126 KJ. Unit of energy is Joule. 1 Joule = 1 watt x 1 sec 1.1 KW = 1100 watt In 1 hour 1.1 KW motor would require 1100 watts x 60 = 66000 Joule / 66 KJ You can't convert that, they measure different things. A watt is a joule per second. The watt (W) is the SI derived unit of power, equal to one joule of energy per second.Power, rated in watts, is the rate of transfer of energy. This can be heat/time or work/time. Either way, a watt is a joule per second.Power A Watt is a unit of power which measures the rate of energy conversion and is defined as one joule per second. There are 1,000 watts in a kilowatt.
