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

About these measurements
Energy can be transferred through work, heating, or electrical processes.
The base reference used here is the joule. One femtojoule is 1e-15 base units; one picojoule is 1e-12 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
