Convert Tesla to Femtotesla
Input the number of teslas you want to convert to femtoteslas.
How to Convert Teslas to Femtoteslas
The tesla and femtotesla are both units of magnetic field. By definition, 1 tesla equals exactly 1e15 femtoteslas. This means to convert teslas to femtoteslas, you multiply by 1e15.
Formula
Step-by-Step Example
Convert 5 T to femtoteslas:
We need to convert teslas to femtoteslas
Since 1 T = 1e15 fT, multiply by 1e15
5 × 1e15 = 5e15
5 T = 5e15 fT

About These Units
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.
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.
