What is a nanojoule per second (nJ/s)?

A nanojoule per second is a unit of power equal to 10⁻⁹ joules per second, representing very small power levels often used in microelectronics and photonics.

What does a megawatt (MW) measure?

A megawatt is a unit of power equal to one million watts, commonly used to rate power plants, large generators, and the electricity demand of cities.

Why are values so small when converting nJ/s to MW?

Because a nanojoule per second is extremely small compared to a megawatt, the conversion results in tiny decimal numbers often best expressed with scientific notation.
