Note, For higher values like 5×103, 10×10-6, 1.6 x1012, enter the value like this for scientific notation as 5e3, 10e-6, 1.6e12, etc.
Conversion Using the Power Formula :
AC Single Phase Joules to Watts Calculation:
The Real power (P) in watts (W) is equal to the energy (E) in joules (J), divided by the time period t in seconds (s):
For example, If the energy consumption of an electrical circuit is 200 joules and takes 20 seconds, what will be the power consumption?
P(W) = 200 ÷ 20
P(W) = 10w
Where:
-
- P = Power in watts
- E = Energy in Joules (j)
- T = time in seconds (sec)

Frequently asked questions
Watts are defined as 1 Watt = 1 Joule per second (1W = 1 J/s) which means that 1 koliwatt = 1000 J/s. A Watt is the amount of energy (in Joules) that an electrical device.
A body is said to have 1 watt of Real power if it can perform 1 joule of work in 1 second. Power is defined as the rate at which work is performed, or energy is converted.
The amount of Real power an appliance uses is determined by its wattage. 1000 watts equals 1 kilowatt. When you run a 1000 watt appliance for an hour you use 1 unit (kilowatt hour) of electricity.
One ampere of current means one Coloumb Of charge flowing through a conductor in one Second. Also, one Ampere of current May be defined as the current flowing through two parallel conductors in the same direction.
As per definition, a 200 watts light bulb requires 200 joules of energy in one second. Hence energy required in One minute will be 60 seconds. The total energy will be transferred = 200 x 60 = 12000 Joules.
