What does petajoule per second measure?

It measures power as energy transfer or consumption at extremely large scales, equal to 10^15 joules per second.

Why convert from petajoule per second to milliwatt?

To translate very large power values into small power units for detailed comparison with electronic devices.

Can this conversion be used for everyday electronics?

Generally no, because petajoule per second is used for huge power flows, while milliwatt suits small electronic components.
