Milliwatts to Gigawatts conversion

How to convert milliwatts to gigawatts?

Sure, let’s start by breaking down how to convert 1 milliwatt (mW) to gigawatts (GW).

Conversion Steps:

1. Understand the Units:

   • 1 watt (W) = 1,000 milliwatts (mW)
   • 1 gigawatt (GW) = 1,000,000,000 watts (W)

2. Convert Milliwatts to Watts:

   • 1 mW = 1 / 1,000 W = 0.001 W

3. Convert Watts to Gigawatts:

   • 0.001 W = 0.001 / 1,000,000,000 GW
   • 0.001 W = 1 × 10^-12 GW

Therefore, 1 milliwatt is equal to 1 × 10^-12 gigawatts.

Real-World Examples of Milliwatts:

1. Laser Pointers:

   • Many consumer-grade laser pointers have power outputs in the range of 1-5 mW. These are used for presentations, pointing out stars during stargazing, or as cat toys.

2. LED Lights:

   • Small LED indicator lights, often found on electronic devices such as routers or power supplies, typically use power in the range of a few milliwatts.

3. Hearing Aids:

   • Modern hearing aids often operate within the range of 1-10 mW, ensuring they provide adequate amplification without excessive power consumption.

4. Wireless Earbuds:

   • Some wireless earbuds may use power in the range of tens to hundreds of milliwatts depending on their activity such as active noise cancellation and Bluetooth connectivity.

5. Sensors:

   • Various types of sensors used in Internet of Things (IoT) devices may consume power in the milliwatt range, allowing them to operate for extended periods on small batteries.

Understanding these practical examples helps contextualize the tiny amounts of power at the milliwatt level compared to the vast power levels measured in gigawatts, such as those used by power plants.
