attotesla to femtotesla
Convert attotesla (aT) to femtotesla (fT). Use an editable magnetic flux density converter, conversion formula, and reference table.
1 aT = 0.001 fT
Conversion formula
One attotesla equals 0.001 femtotesla. Multiply your value in attotesla by this factor to get femtotesla. For the reverse conversion, divide by the same factor.
Worked example
To convert 5 attotesla:5 × 0.001 = 0.005 fT

About these measurements
Magnetic flux density describes a magnetic field over area.
The base reference used here is the tesla. One attotesla is 1e-18 base units; one femtotesla is 1e-15 base units.
Important distinctions
One gauss equals 0.0001 tesla.
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 aT to fT?
Multiply the quantity in aT 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 femtotesla to attotesla converter.
