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.

How do you convert 1997436.144 Kilojoule to KiloWAtt?

You can't convert from Joules to Watts because Joules is a measure of total energy, and Watts measure energy per second.


How many joules of light energy are in 1440 watts of electrical energy?

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.

What equals 100 watts?

That depends what you want to convert it to. Watt is a unit of power. 100 watts is equal to:0.1 kilowatts100 joules/second


Can you convert from joules to photons?

Joules is a unit of energy; watts is a unit of power. You can't just convert it. The relationship between the two is: power = energy / time in units: watts = joules / second


How many watts are 4680000000joules?

Watts are a measure of power, Joules are a measure of energy. The energy is equal to the power times the time. So if you have a power of 5 watts running for 7 seconds, that is 5x7 Joules of energy, or 35 Joules. Looked at another way, power measures how fast energy is converted. So 35 Joules converted in 7 seconds would be 5 watts of power, but it would need 35 watts to convert that energy in 1 second.


How much power in watts will an led bulb consume if its energy is 6 joules?

Joules (energy) are not equivalent to Watts (power).If something converts 6 Joules every second, it is 6 Watts. If it takes ten seconds to convert 6 Joules, its power is 0.6 Watts.Multiply the Watts by the seconds to find the Joules.CommentYou do not 'consume' power. Power is simply a rate; you cannot consume a rate! You consume energy; the rate at which you consume it is power.


How you convert 36watts in joules?

Watts is a unit of power; Joules is a unit of energy. Watts means Joules/second, so you would need to know how long a machine that uses 36 watts (for example, certain light-bulbs) is used.36 watts is simply 36 Joules per second; this is the same as 2160 Joules per minute, or 129,600 Joules per hour.Since the electricity bill is measured in kWh instead of Joule (1 kWh = 3,600,000 Ws = 3,600,000 Joule), you might also say that a device that uses 36 watts uses 0.036 kWh every hour.


How do you convert Mega Joules to Joules?

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.


What is the relationship between watts and energy output?

Watts is energy output. Watts is joules per second. Joules is energy.


How many joules are in 59.4 watts?

"59.4 watts" means "59.4 joules every second"


Calculate the power in watts used if you exert 50 joules of work in 5 seconds?

Watts is joules per second, so 50 joules in 5 seconds is 10 watts.


How do you convert Volt Ampere into Joules?

You can't. If you know the voltage (volts) and current (amperes), you can convert to power (watts), but power is not energy. Power is the rate of energy (joules per second). You need to know the time as well to determine energy.
