A milliwatt is one thousandth of a watt, measuring the rate of energy transfer equal to one joule per second, commonly applied to low power devices.

How large is a gigajoule per second compared to a milliwatt?

One gigajoule per second equals one billion watts, making it vastly larger than a milliwatt by a factor of 10^12.

When should I convert milliwatts to gigajoules per second?

This conversion is useful for understanding power relationships from small electronic devices up to massive industrial or power generation scales.

Key Terminology

Milliwatt [mW]: A unit of power equal to one thousandth of a watt, measuring small-scale energy transfer in electronic or optical devices.
Gigajoule/second [GJ/s]: A power unit equal to one billion joules transferred per second, typically representing very large energy outputs like those from power plants.

Quick Knowledge Check

What does 1 milliwatt represent in terms of watts?

One thousand watts

One thousandth of a watt

One million watts

Which unit measures very large continuous power output?

Milliwatt (mW)

Gigajoule per second (GJ/s)

Watt (W)

Why is converting from mW to GJ/s challenging?

Because both units measure the same power level

Because of the huge difference in scale between the units

Because gigajoule per second is smaller than milliwatt
