Dimensions are very useful for qualitative checks of equations.
| Quantity | Dimensions | Units |
| Kinetic energy | 
|
kg m 2 s -2 = N m = J (joule) |
| Zeeman interaction | 
|
kg m 2 s -2 = N m = J (joule) |
| Coulomb interaction energy | 
|
kg m 2 s -2 = N m = J (joule) |
| Permittivity of vacuum | 
|
A s V -1 m -1 = F m -1 = A 2 s 4 kg -1 m -3 |
| Permeability of vacuum | 
|
H m -1 = T m A -1 = Wb A -1 m -1 = V s A -1 m -1 |
| Thermal energy, Amount of heat | 
|
kg m 2 s -2 = N m = J (joule) |
Angular momentum 
|
|
kg m 2 s -1 = J s |
| Magnetic moment | 
|
A m2 |
|
Magnetic field B (Magnetic flux density) |
|
Wb/m2 = kg·s-2·A-1 = T (tesla) |
| gyromagnetic ratio | 
|
A s kg -1 = C kg -1 = s -1 T -1 |
| Gravitational constant | 
|
m 3 kg -1 s -2 = N m 2 kg -2 |
