An attowatt is a unit of power equal to 10⁻¹⁸ watts, used for very small power levels in scientific measurements.

What is a gigawatt used for?

A gigawatt represents one billion watts and is commonly used to express the output of large power plants or grid capacities.

Why convert attowatts to gigawatts?

Converting from attowatts to gigawatts helps relate tiny power measurements in experimental settings to more tangible large-scale power units.

How to Use This Tool?

Enter the power value in attowatts [aW] you wish to convert
Select attowatt as the original unit and gigawatt [GW] as the target unit
Click the convert button to see the equivalent value in gigawatts
Review the result to understand the power scale difference

Key Features

Converts power values between attowatts and gigawatts accurately
Ideal for fields ranging from nanoelectronics to energy production
Browser-based and user-friendly interface
Supports scientific and engineering power unit contexts

Examples

5 attowatts [aW] converts to 5 × 10⁻²⁷ gigawatts [GW] or 5e-27 GW
100 attowatts [aW] equals 1 × 10⁻²⁵ gigawatts [GW] or 1e-25 GW

Common Use Cases

Relating optical power levels from ultra-sensitive photon detectors to larger power scales
Understanding power dissipation in nanoelectronic devices and low-power sensors in terms of large-scale power units
Comparing experimental physics and astronomy detector outputs with national or utility-scale power generation figures

Tips & Best Practices

Remember the enormous difference in magnitude between attowatts and gigawatts when interpreting results
Use this conversion mainly for conceptual or educational purposes rather than direct practical comparison
Consider the context of measurement uncertainty at extremely low power levels such as attowatts

Limitations

The conversion covers extreme scales making direct practical use uncommon
Precision limitations exist when measuring attowatt-level power due to sensitivity and uncertainty
Such conversions are usually more conceptual to bridge understanding between nano-scale and large-scale power
