Not to look a gift horse in the mouth, but for me, this would give it the finest set of pearly whites. I use these for electronic compass applications at work. I understand if it's of no use to anyone else though. A wise old co-worker once told me that 'we as engineers are not demographically significant'.
Scientific units/Magnetic field:
From Wikipedia (Tesla)
1 tesla is equivalent to:
10,000 (or 104) G (gauss), used in the CGS system. Thus, 10 G = 1 mT (millitesla), and 1 G = 10−4 T.
1,000,000,000 (or 109) γ (gammas), used in geophysics. Thus, 1 γ = 1 nT (nanotesla)
For those concerned with low-frequency electromagnetic radiation in the home, the following conversions are needed most:
1000 nT (nanotesla) = 1 µT (microtesla) = 10 mG (milligauss)
1,000,000 µT = 1 T
