Conversion Results

Enter power and time values to calculate energy

Watts to Joules conversion helps you calculate how much energy (in Joules) is consumed or produced based on power (Watts) and time (Seconds). This Watts to Joules Converter by SantPro Tools makes it effortless to calculate energy quickly and accurately for any electrical or mechanical system.

Whether you are a student, an engineer, or simply curious about power consumption, the Watts to Joules Calculator will provide you with the energy values in Joules (J) immediately - allowing you to come to a conclusion about how much energy might be used by an appliance over a period of time.

Watts to Joules Converter

What Are Joules and Watts?

The Watts to Joules conversion is based on the simple physics formula:

E = P x t

Where:

E = Energy in Joules (J)
P = Power in Watts (W)
t = Time in Seconds (s)

This means 1 Watt for 1 second equals 1 Joule.

For example, if a 100W bulb runs for 3600 seconds (1 hour), it uses:

100 x 3600 = 360,000 Joules

Using SantPro Tools' Watts to Joules Converter, you can easily do these calculations in a much quicker time than doing it manually, and voiding manual errors.

FAQs

The formula is Energy (J) = Power (W) x Time (s). Multiply watts by seconds to get energy in joules.

1 Watt equals 1 Joule per second. This means 1W = 1J/s.

Use the Watts to Joules Converter. Just input the power in watts and the time in seconds, and the utility will calculate the energy instantly.

Yes. Divide the total Joules by time (seconds) to get power in watts. Formula: Power (W) = Energy (J) ÷ Time (s).

Definitely! It is widely utilized in physics, for electrical engineering, and for determining energy consumption with respects to so many things ranging from bulbs, motors, and appliances.

Yes. This converter or calculator will even show you the energy results in kWh (kilowatt-hours) and calories so it can be useful in more scientific ways and for household appliances.
