Unit of EC is?

• The unit of EC, which stands for electrical conductivity, can be expressed in several different ways, all of which are technically correct:
-Micro mhos/cm: This is a common unit used in many fields, particularly agriculture and environmental science. "Mhos" is the reciprocal of ohms, the unit of electrical resistance. 1 mhos/cm is equal to 1 Siemens/meter (S/m), the SI unit of conductivity.
-dSm⁻¹: This is another common unit, with "ds" representing decisemens (1 ds = 0.1 S).
-Milli mhos/cm: This unit is also frequently used, with "mS" representing milli siemens (1 mS = 0.001 S).
