Frequently Asked Questions
-
What is a femtowatt used to measure?
-
A femtowatt measures extremely small power levels, often used in contexts like radio astronomy, ultra-sensitive photodetection, and nanoscale electronics.
-
How does a centiwatt compare to a watt?
-
A centiwatt is one hundredth of a watt, representing a low power unit commonly used for small electronics and sensor power measurements.
-
Why might converting from femtowatt to centiwatt be useful?
-
Converting femtowatts to centiwatts helps relate ultra-small power levels to more practical low-power units seen in microelectronics and sensing applications.
Key Terminology
-
Femtowatt (fW)
-
An SI derived power unit equal to 10⁻¹⁵ watt, used for measuring extremely low energy transfer rates in sensitive and nanoscale systems.
-
Centiwatt (cW)
-
A power unit equal to one hundredth of a watt (10⁻² W), commonly used to quantify very low power levels in electronics and sensors.
