What does 1 milliwatt represent in SI units?

One milliwatt is one thousandth of a watt and measures power transfer at a rate of one joule per second.

How is joule per second related to watt?

A joule per second is exactly equal to a watt; both measure power as energy transfer per unit time.

Why convert milliwatt to joule per second?

Converting to joule per second expresses power in the standard SI unit, which helps compare and communicate power levels across various scientific and engineering fields.
