- Field Detail
  - ampere
```
public static BaseUnit ampere
```
    Base unit of electric current. The ampere is that constant current which, if maintained in two straight parallel conductors of infinite length, of negligible circular cross section, and placed 1 meter apart in vacuum, would produce between these conductors a force equal to 2 x 10^-7 newton per meter of length.
  - candela
```
public static BaseUnit candela
```
    Base unit of luminous intensity. The candela is the luminous intensity, in a given direction, of a source that emits monochromatic radiation of frequency 540 x 10^12 hertz and that has a radiant intensity in that direction of (1/683) watt per steradian.
  - kelvin
```
public static BaseUnit kelvin
```
    Base unit of thermodynamic temperature. The kelvin, unit of thermodynamic temperature, is the fraction 1/273.16 of the thermodynamic temperature of the triple point of water.
  - kilogram
```
public static BaseUnit kilogram
```
    Base unit of mass. The kilogram is the unit of mass; it is equal to the mass of the international prototype of the kilogram.
  - meter
```
public static BaseUnit meter
```
    Base unit of length. The meter is the length of the path travelled by light in vacuum during a time interval of 1/299 792 458 of a second.
  - second
```
public static BaseUnit second
```
    Base unit of time. The second is the duration of 9 192 631 770 periods of the radiation corresponding to the trasition between the two hyperfine levels of the ground state of the cesium-133 atom.
  - mole
```
public static BaseUnit mole
```
    Base unit of amount of substance. The mole is the amount of substance of a system which contains as many elementary entities as there are atoms in 0.012 kilogram of carbon 12.
  - radian
```
public static BaseUnit radian
```
    Base unit of angular measure. The radian is the plane angle between two radii of a circle that cut off on the circumference an arc equal in length to the radius. This unit is dimensionless.
  - steradian
```
public static BaseUnit steradian
```
    Base unit of solid angle. The steradian is the solid angle that, having its vertex in the center of a sphere, cuts off an area of the surface equal to that of a square with sides of length equal to the radius of the sphere. This unit is dimensionless.
