What Is This Tool?
This converter allows users to translate power values from milliwatts, a standard unit for low power in electronics, to femtojoules per second, a unit representing extremely small power levels used in advanced physics and nano-scale applications.
How to Use This Tool?
-
Enter the power value in milliwatt (mW) you want to convert
-
Select femtojoule per second (fJ/s) as the target unit
-
Click the convert button to see the equivalent power in femtojoule per second
-

Key Features
-
Converts power units from milliwatt (mW) to femtojoule per second (fJ/s)
-
Based on a precise conversion rate suitable for nanoelectronic and quantum physics use cases
-
Simple interface for quick and accurate conversions
-
Supports conversion of very small power values to extremely fine units
Examples
-
0.5 milliwatt converts to 500,000,000,000 femtojoule per second
-
2 milliwatts converts to 2,000,000,000,000 femtojoule per second
Common Use Cases
-
Measuring power consumption in small electronic components like LEDs and sensors
-
Quantifying energy dissipation in ultra-low-power nanoelectronic circuits
-
Describing power levels in single-photon detectors and molecular-scale devices
-
Reporting minute heat loads or background power in quantum experiments
Tips & Best Practices
-
Use scientific notation when dealing with very large converted values for better readability
-
Apply this conversion mainly in contexts requiring ultra-high precision measurement
-
Verify units carefully to ensure appropriate use in electronics, optics, or quantum physics
-
Prefer milliwatt units for typical electronic applications unless extremely fine measurement is needed
Limitations
-
Conversions produce very large numbers that can be challenging to interpret without scientific notation
-
Femtojoule/second units are primarily applicable to ultra-precise measurement contexts
-
Typical electronic applications usually do not require femtojoule/second scale, making milliwatts preferable
Frequently Asked Questions
-
What does 1 milliwatt equal in femtojoule per second?
-
1 milliwatt equals 1,000,000,000,000 femtojoule per second.
-
Why convert milliwatts to femtojoule per second?
-
To express power levels from small electronics in extremely small units needed for nanoelectronic and quantum physics measurements.
-
Are femtojoule per second units used in typical electronic devices?
-
No, these units are mostly relevant in ultra-precise and experimental physics contexts, not common electronics.
Key Terminology
-
Milliwatt [mW]
-
A milliwatt is one thousandth of a watt, representing power equal to one joule per second, commonly used for low power electronics.
-
Femtojoule/second [fJ/s]
-
A femtojoule per second is a unit of power equal to 10^-15 watts, used to quantify extremely small rates of energy transfer in nanoelectronics and quantum experiments.
