Convert Milligauss to Femtotesla

Convert milligauss to femtoteslas by entering a value below.

1 mG (milligauss) = 1e17 fT (femtoteslas)

How to Convert Milligauss to Femtoteslas

The milligauss and femtotesla are both units of magnetic field. By definition, 1 milligauss equals exactly 1e17 femtoteslas. This means to convert milligauss to femtoteslas, you multiply by 1e17.

Formula

femtoteslas = milligauss × 1e17

Step-by-Step Example

Convert 5 mG to femtoteslas:

1
Convert 5 mG to femtoteslas

We need to convert milligauss to femtoteslas

2
Apply the formula

Since 1 mG = 1e17 fT, multiply by 1e17

5 × 1e17 = 5e17

Answer

5 mG = 5e17 fT

About These Units

Milligauss (mG)

A milligauss (mG) equals 0.001 gauss or 0.1 microtesla. Used for environmental magnetic field measurements. Power lines: 1-100 mG at distance. Computer monitors: 1-25 mG. Background urban level: 0.5-4 mG. EMF meters often display milligauss.

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.
