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 Watts to Joules Calculation:
The Energy (E) in joules (J) is equal to the Real Power (P) in watts (W), times the time period t in seconds (sec):
For example, The Energy (E) consumption of an electrical circuit that has a Real power (P) consumption of 50 watts for a time duration of 6 seconds.
J = 50 × 6
J = 300
Where:
-
- E = Energy in Joules (j)
- P = Real Power in Watts (W)
- T = time in seconds (sec)

Frequently asked questions
1 Joule (Joule per second) = 1 watts (w).
energy in joules for a 140-watt power consumption over 20 seconds: E(J) = 140 W × 20 s = 2800 J
The watts to joules formula is:
E(J) = P(W) × T (s)
E(J) = 100 W × 50 s
E(J) = 5,000 J
Power: energy (E) provided per unit of time. Energy is measured in joules (J) and Real power is measured in Watts (W). A watt is equal to a joule per second.
