What does kilojoule per second (kJ/s) measure?

Kilojoule per second measures the rate of energy transfer equal to 1,000 joules per second and represents large power outputs.

When should I use nanowatt (nW) as a power unit?

Nanowatt is used to quantify extremely low power levels such as those found in precision electronics, photonics, and ultra-low-power sensors.

How do I convert from kilojoule/second to nanowatt?

Multiply the value in kilojoule/second by 1,000,000,000,000 to get the equivalent power in nanowatt.

What Is This Tool?

This tool helps convert power measurements from kilojoule per second (kJ/s), used for rating high power outputs, to nanowatt (nW), which measures extremely low power levels.

How to Use This Tool?

Enter the power value in kilojoule per second (kJ/s) you want to convert
Select kilojoule/second as the input unit and nanowatt as the output unit
Click on the convert button to get the result in nanowatt (nW)
Review the converted value and use the examples as reference

Key Features

Converts kilojoule/second (kJ/s) to nanowatt (nW) accurately based on defined conversion rates
Supports power measurements ranging from large-scale industrial outputs to ultra-low power devices
Browser-based and easy to use with intuitive input and output fields
Provides clear examples to illustrate conversions

Examples

Converting 2 kJ/s results in 2 × 1000000000000 nW = 2000000000000 nW
Converting 0.5 kJ/s results in 0.5 × 1000000000000 nW = 500000000000 nW

Common Use Cases

Assessing electrical or mechanical power output of motors and industrial machinery in very small power units
Quantifying power consumption of ultra-low-power microcontrollers and IoT devices in deep-sleep modes
Measuring optical or electrical signals from weak light sources and precision photonic instruments
Scaling power outputs from large turbines or engines to tiny energy harvesting devices

Tips & Best Practices

Double-check unit selections before converting to avoid scale confusion
Use this conversion when needing to express high power rates into extremely small units for analysis
Apply sensitive measurement equipment when dealing with nanowatt values
Be mindful of the large scale difference to prevent computational or interpretation errors

Limitations

Significant scale difference between kilojoule/second and nanowatt can cause errors if not handled carefully
Nanowatt values require highly sensitive instruments and are only suitable for very low power levels
Kilojoule/second units are designed for large-scale power ratings, making direct comparisons challenging
