nanojoule to microjoule
Convert nanojoule (nJ) to microjoule (μJ). Use an editable energy converter, conversion formula, and reference table.
1 nJ = 0.001 μJ
Conversion formula
One nanojoule equals 0.001 microjoule. Multiply your value in nanojoule by this factor to get microjoule. For the reverse conversion, divide by the same factor.
Worked example
To convert 5 nanojoule:5 × 0.001 = 0.005 μJ

About these measurements
Energy can be transferred through work, heating, or electrical processes.
The base reference used here is the joule. One nanojoule is 1e-9 base units; one microjoule is 0.000001 base units.
Important distinctions
Calorie and BTU definitions vary. These pages label thermochemical calories and International Table BTUs explicitly.
Precision
The converter uses stored conversion factors and floating-point arithmetic. Results display up to ten significant digits, switching to scientific notation for very small or large values. Keep the precision of your original measurement when reporting results.
Common questions
How do I convert nJ to μJ?
Multiply the quantity in nJ by 0.001. You can also type the value into the converter above.
Can I reverse the conversion?
Yes. Use the swap button or open the microjoule to nanojoule converter.
