Joules (J) to Watts (W) Calculator
Power in watts:
Calculation Formula
P(W) = E(J) / t(s)
Where:
- P(W) is the power in watts
- E(J) is the energy in joules
- t(s) is the time period in seconds
How to Convert Joules to Watts
To convert from joules (J) to watts (W), you need to know the time period over which the energy is expended. Watts are a measure of power, which is energy per unit time.
The power P in watts (W) is equal to the energy E in joules (J), divided by the time period t in seconds (s):
Example
What is the power consumption in watts when the energy consumption is 90 joules for a time duration of 3 seconds?
P = 90J / 3s = 30W
Joules to Watts Conversion Table
| Energy (J) | Time (s) | Power (W) |
|---|---|---|
| 1 J | 1 s | 1 W |
| 10 J | 1 s | 10 W |
| 10 J | 2 s | 5 W |
| 100 J | 5 s | 20 W |
| 1000 J | 10 s | 100 W |
| 3600 J | 3600 s | 1 W |
