## Ω as unit of measure:

**Ohm **– unit of electrical resistance in the International system of units (SI), named after German scientist Georg Simon Ohm.

**Ohm** as the unit of measurement is the Russian designation and international code – Ω.

**Ohms** is equal to electrical resistance of the conductorbetween whose ends there is a voltage of 1 V at a DC current of 1 ampere.

**1 Ohm** is an electrical resistance between two points of a conductorwhen a constant potential difference of 1 volt, applied to these points, giving the conductor a current of 1 ampere, and the conductor is not valid any electromotive force.

Om = (kg · m2) / (A2· S3) = B / A.

1 Ohm = (1 kg · 1 m2) / (1 A2· 1 S3) = 1 V / 1 A.

In the International system of units ohms introduced by the decision of the XI General conference on weights and measures in 1960, simultaneously with the adoption of the SI as a whole. In accordance with the rules SI, and relating the derived units are named for scientists, the name of the unit “Ohm” spelled with a lowercase letter and its name — with a capital (Ohms). Such writing of the designation is stored in the symbols for derived units formed by using Ohm.

Unit, reverse WMD is Siemens — unit of electrical conductivity in SI.

## The application of Ohm:

Ohms measure electrical resistance in the conductors.

## View Ohm other units – of the formula:

Through the basic and derived SI units of Ohm is expressed in the following way:

Om = (kg · m2) / (A2· S3)

Ohm = V / A

Ω = B2 / W

Ω = W / A2

Ω = 1 / Cm

where A is amperes, In volts, m – meter, s – second W – watt, kg – kilogram, Cm – Siemens.

## Multiple and sub-multiple units Ohm’s:

Multiple and sub-multiple units are formed using standard prefixes of the SI.
