1 T to 2.4 T – coil gap of a typical loudspeaker magnet; 1.5 T to 3 T – strength of medical magnetic resonance imaging systems in practice, experimentally up to 17 T [10] 4 T – strength of the superconducting magnet built around the CMS detector at CERN [11] 5.16 T – the strength of a specially designed room temperature Halbach array [12]

To help compare different orders of magnitude, this section lists lengths between 10 −2 m and 10 −1 m (1 cm and 1 dm). 1 cm – 10 millimeters; 1 cm – 0.39 inches; 1 cm – edge of a square of area 1 cm 2; 1 cm – edge of a cube of volume 1 mL; 1 cm – length of a coffee bean; 1 cm – approximate width of average fingernail
The gal is a derived unit, defined in terms of the centimeter–gram–second (CGS) base unit of length, the centimeter, and the second, which is the base unit of time in both the CGS and the modern SI system. In SI base units, 1 Gal is equal to 0.01 m/s 2.
The conversion factor is 10 8 maxwell per weber, since flux is the integral of field over an area, area having the units of the square of distance, thus 10 4 G/T (magnetic field conversion factor) times the square of 10 2 cm/m (linear distance conversion factor). 10 8 Mx/Wb = 10 4 G/T × (10 2 cm/m) 2.
5.29 × 10 −11 m (52.9 pm) The Bohr radius ( a 0 {\displaystyle a_{0}} ) is a physical constant , approximately equal to the most probable distance between the nucleus and the electron in a hydrogen atom in its ground state .
In general, the masses of all hadrons are of the order of 1 GeV/c 2, which makes the GeV/c 2 a convenient unit of mass for particle physics: [4] 1 GeV/ c 2 = 1.782 661 92 × 10 −27 kg . The atomic mass constant ( m u ), one twelfth of the mass a carbon-12 atom, is close to the mass of a proton.
Unit cell definition using parallelepiped with lengths a, b, c and angles between the sides given by α, β, γ [1]. A lattice constant or lattice parameter is one of the physical dimensions and angles that determine the geometry of the unit cells in a crystal lattice, and is proportional to the distance between atoms in the crystal.
