This resistance converter features 22 units of electrical resistance, enabling arbitrary conversion between different units. All resistance values are converted in real time and displayed with up to 20 decimal places, ensuring sufficient accuracy.


Two Steps to Your Result

Step 1: Select the required units

Our resistance converter offers several input fields, each displaying the current unit symbol (for example, Ω, mΩ or kΩ). To change a unit, simply click on the unit symbol and select your preferred measurement from the dropdown menu.

Step 2: Enter your value

Once you have selected the desired units in the resistance converter, simply enter the value you want to convert. You can input numbers into any of the available fields. As soon as you enter a value in one field, all other fields will automatically update and display the converted results. Both the entered value and the calculated results are automatically rounded to the predefined number of decimal places.

Add-on features

At the bottom of the resistance converter, you will find two green buttons. The button on the right resets the converter to its default state. This restores all units, values, and decimal settings to their original configuration. The button on the left clears the current inputs by setting all values to zero, while keeping your selected units and decimal settings unchanged.


Conversion table for resistance units

Electrical resistance is always specified with a value and the corresponding unit. A conversion table can be used to determine the value of the known resistance in another unit. For example: How many ohms [Ω] are in 1 megaohm [MΩ]?. In most cases, a conversion table is used to determine the conversion factor or calculation method for converting one unit of electrical resistance into another. However, the tables are usually very confusing and difficult for inexperienced users to understand.

The following tool is available as a solution to this problem, allowing conversion factors and calculation methods to be queried directly from the conversion table. The conversion table covers a total of 22 internationally common units of electrical resistance.

Conversion of resistance units in everyday life

There are many units of electrical resistance that are rarely used in everyday life. These include, for example, hectohms [hΩ], deciohms [dΩ] and statohms [statΩ]. It is also rather unlikely that conversions will be made between a very small resistance unit and petaohms [PΩ]. For this reason, it is not necessary to know all conversion values by heart. However, there are resistance units that are used very frequently in everyday life. Examples include ohms [Ω], kiloohms [kΩ], and megaohms [MΩ]. For these resistance units, it can be very helpful to know the calculation method and the conversion value by heart.


Converting ohms and milliohms

Converting between ohms [Ω] and milliohms [mΩ] is very simple. A conversion factor of 1,000 is used for the calculation. The value in ohms [Ω] multiplied by 1,000 gives the value in milliohms [mΩ]. Dividing the value in milliohms [mΩ] by 1,000 gives the value in ohms [Ω].

  • Milliohms [mΩ] = ohms [Ω] * 1,000
  • Ohms [Ω] = milliohms [mΩ] ÷ 1,000

Converting ohms and kiloohms

Ohms [Ω] and kiloohms [kΩ] belong to the metric system of units, which makes conversion very easy. A conversion value of 1,000 is used for the calculation. The value in kiloohms [kΩ] multiplied by 1,000 gives the value in ohms [Ω]. Dividing the value in ohms [Ω] by 1,000 gives the value in kiloohms [kΩ].

  • Ohms [Ω] = kiloohms [kΩ] * 1,000
  • Kiloohms [kΩ] = ohms [Ω] ÷ 1,000

Converting ohms and megaohms

The prefix "mega" comes from the decimal system and is based on a power of ten with a value of 106. This value can be used to convert between ohms [Ω] and megaohms [MΩ]. The value in megohms [MΩ] multiplied by 106 gives the value in ohms [Ω]. Dividing the value in ohms [Ω] by 106 gives the value in megohms [MΩ].

  • Ohm [Ω] = megaohm [MΩ] * 106
  • Megaohm [MΩ] = ohm [Ω] ÷ 10

Converting megaohms and kiloohms

While the prefix "mega" corresponds to a value of 106, "kilo" stands for a value of 103. A megaohm [MΩ] is therefore a thousand times greater than a kiloohm [kΩ], which is also the conversion factor. The value in megaohms [MΩ] multiplied by 1,000 gives the value in kiloohms [kΩ]. Dividing the value in kiloohms [kΩ] by 1,000 gives the value in megaohms [MΩ].

  • Kiloohm [kΩ] = megaohm [MΩ] * 1,000
  • Megaohm [MΩ] = kiloohm [kΩ] ÷ 1,000
