What does joule per second (J/s) measure?

Joule per second (J/s) is an SI unit of power representing the rate at which energy is transferred or converted, equal to one watt.

Why use decijoule per second instead of joule per second?

Decijoule per second is useful for expressing smaller power levels more precisely, especially in low-power electronics and small-scale thermal power measurements.

How do I convert joule per second to decijoule per second?

Multiply the power value in joule per second by 10 to get the equivalent in decijoule per second.
