What is a picowatt used to measure?

A picowatt measures extremely small power levels such as noise in cryogenic detectors, leakage power in ultra-low-power electronics, and faint astronomical signals.

How do I convert picowatts to watts?

Multiply the picowatt value by 1 × 10⁻¹², since 1 picowatt equals one trillionth of a watt.

Why is converting to watts important?

Converting to watts allows expressing very small power measurements in a standard SI unit, enabling compatibility with broader scientific and engineering calculations.
