ProfessorJoules and watts are not directly convertible since they are different units of measurement. Joules measure energy, while watts measure power. Power is the rate at which energy is transferred, so if you know the time taken to transfer a certain amount of energy in joules, you can calculate the power in watts using the formula Power (Watts) = Energy (Joules) / Time (seconds).
Calorie is the unit of energy in CGS system of unit.
Joule is the unit of energy in general in MKS system of units.
Now we must get the relation between these two or tables connecting these.
1 cal = 4.18 J
1 K cal = 4180 J
Suppose you rub you hands spening an energy of 4.18 J then 1 cal of heat will be produced.

"Heat" is just a form of "energy". When working with their quantities,
there's no difference, and they're interchangeable.

How many joules of light energy are in 1440 watts of electrical energy?
To calculate the energy in joules, you can use the formula: energy (joules) = power (watts) × time (seconds). If you have 1440 watts of electrical power and want to calculate the energy in joules for a specific time period, you would need to know the time duration in seconds.
60-watt light bulb in jouls?
To calculate the energy used by a 60-watt light bulb in joules, you need to convert the power (watts) to energy (joules). First, convert watts to joules per second (1 watt = 1 joule/second), then multiply by the time the light bulb is on. So, for example, if the light bulb is on for 1 hour (3600 seconds), the energy used would be 60 watts * 3600 seconds = 216,000 joules.
What is the watts equivalent of 231000 joules?
231,000 joules is an amount of energy, while watts are a measure of how fast energy is used or converted. 231,000 joules could be used by 1 watt running for 231,000 seconds, or 231 watts running for 1000 seconds, etc. Energy = power x time, so 1000 watts for 231 seconds is an amount of energy equal to 231,000 joules.
How many watts does 2400 joules equal?
To convert joules to watts, you need to know the time over which the energy is expended. Watts are a unit of power, which is energy per unit time. If the time is known, you can use the formula: Watts = Joules / seconds.
How much work can a 500 watt electric mixer do in 2.50 minutes?
The work done by an electric mixer can be calculated by multiplying the power (500 watts) by the time (2.50 minutes) in seconds. First, convert the time to seconds: 2.50 minutes = 150 seconds. Then, calculate the work done: Work = Power x Time = 500 watts x 150 seconds = 75,000 joules.
