The Ohm Converter supports 22 different units. This makes it possible to convert freely between ohms [Ω] and other internationally common units of electrical resistance. All resistance values are converted in real time and displayed with up to 20 decimal places, ensuring sufficient accuracy.
Conversion of ohms
To convert ohms [Ω] into another unit of electrical resistance, a conversion value is required. This value can be determined using a conversion table. However, the table is relatively large and confusing, making it difficult for inexperienced users to understand. The following tool provides a solution to this problem by allowing the rounded conversion values for ohms [Ω] to be queried directly from the conversion table.
Determine conversion factor
Conversion between ohms and gigaohms
A quick and precise conversion between ohms [Ω] and gigaohms [GΩ] is straightforward and requires only multiplication or division by 109. The conversion from gigaohms [GΩ] to ohms [Ω] is done by multiplying the value in gigaohms [GΩ] by 109. To reverse the conversion, divide the value in ohms [Ω] by 109 to obtain gigaohms [GΩ].
- Ohms [Ω] = gigaohms [GΩ] * 109
- Gigaohms [GΩ] = ohms [Ω] ÷ 109
Conversion between ohms and megaohms
Conversions between ohms [Ω] and megaohms [MΩ] are straightforward and can be performed with simple math. The required conversion factor is 1,000,000. To convert a value from megaohms [MΩ] to ohms [Ω], multiply the number of megaohms [MΩ] by 1,000,000. For values in ohms [Ω], divide by 1,000,000 to get the equivalent in megaohms [MΩ].
- Ohms [Ω] = megaohms [MΩ] * 1,000,000
- Megaohms [MΩ] = ohms [Ω] ÷ 1,000,000
Conversion between ohms and kiloohms
The conversion between ohms [Ω] and kiloohms [kΩ] is quick to perform and requires only basic mathematical operations an the conversion factor 1,000. Multiply the number of kiloohms [kΩ] by 1,000 to get the converted value in ohms [Ω]. To convert a value in ohms [Ω] back to kiloohms [kΩ], simply divide the amount of ohms [Ω] by 1,000.
- Ohms [Ω] = kiloohms [kΩ] * 1,000
- Kiloohms [kΩ] = ohms [Ω] ÷ 1,000
Conversion between ohms and milliohms
Ohms [Ω] and milliohms [mΩ] can be converted quickly and accurately with just a simple multiplication or division using the conversion factor 1,000. Converting ohms [Ω] to milliohms [mΩ] is performed by multiplying the number of ohms [Ω] by 1,000. To convert a value from milliohms [mΩ] to ohms [Ω], divide the number of milliohms [mΩ] by 1,000.
- Milliohms [mΩ] = ohms [Ω] * 1,000
- Ohms [Ω] = milliohms [mΩ] ÷ 1,000
Conversion between ohms and microohms
A quick and precise conversion between ohms [Ω] and microohms [µΩ] is straightforward and requires only multiplication or division by 1,000,000. The conversion from ohms [Ω] to microohms [µΩ] is done by multiplying the value in ohms [Ω] by 1,000,000. To reverse the conversion, divide the value in microohms [µΩ] by 1,000,000 to obtain ohms [Ω].
- Microohms [µΩ] = ohms [Ω] * 1,000,000
- Ohms [Ω] = microohms [µΩ] ÷ 1,000,000
