How to Convert Femtoteslas to Teslas
The femtotesla and tesla are both units of magnetic field. By definition, 1 tesla equals exactly 1e15 femtoteslas. This means to convert femtoteslas to teslas, you divide by 1e15.
Formula
Step-by-Step Example
Convert 5 fT to teslas:
We need to convert femtoteslas to teslas
Since 1 T = 1e15 fT, divide by 1e15
5 ÷ 1e15 = 5e-15
5 fT = 5e-15 T

About These Units
Femtotesla (fT)
A femtotesla (fT) equals 10⁻¹⁵ teslas. Measures biomagnetic fields: human brain activity 10-1000 fT, human heart (MCG) 1-100 pT. SQUID sensors can detect sub-femtotesla fields. At the frontier of magnetic field measurement.
Tesla (T)
The tesla (T) is the SI unit of magnetic flux density (magnetic field strength). Named after Nikola Tesla. MRI machines: 1.5-7 T, neodymium magnet surface: 1-1.4 T, Earth's field: ~50 μT. One tesla = one weber per square meter = 10,000 gauss.
