Electrical Resistance Converter
Electrical resistance is a fundamental property of objects that describes their opposition to the flow of electric current. It is denoted by the symbol "R" and measured in ohms (Ω). The resistance of an object depends on its physical characteristics, such as its length, cross-sectional area, and the type of material it is made of. Understanding and accurately converting resistance units are essential for various fields, including electronics, electrical engineering, and physics.
Ohm (Ω): The Ohm is the base unit of electrical resistance in the International System of Units (SI). One ohm is equal to the resistance when one volt of electrical potential creates a current of one ampere.
Conversion Factor: 1 Ω = 1 V/A
Kiloohm (kΩ): One Kiloohm is equal to 1,000 ohms. It is frequently used in electrical engineering for moderate resistance values.
Conversion Factor: 1 kΩ = 1,000 Ω
Megaohm (MΩ): One Megaohm is equal to 1,000,000 ohms. It is a large unit of resistance commonly used in electronic circuits to measure high resistance values.
Conversion Factor: 1 MΩ = 1,000,000 Ω
Milliohm (mΩ): One milliohm is equal to 0.001 ohms. Milliohms are used to measure low resistance values, particularly in electronic components like resistors and conductors.
Conversion FActor: 1 mΩ = 0.001 Ω
Microohm (μΩ): One microohm is equal to 0.000001 ohms. Microohms are used for extremely low resistance values, such as in the measurement of small electrical resistances or wire conductance.
Conversion Factor: 1 μΩ = 0.000001 Ω
Volt / ampere (V/A): Volt per ampere (V/A) is a derived unit representing the resistance of a device or component when the voltage is divided by the current passing through it. It has the same value as ohms.
Conversion Factor: 1 V/A = 1 Ω
Abohm (abΩ): The Abohm is an older unit of resistance used in the centimeter-gram-second (CGS) system. One Abohm is the equivalent of 10^-9 ohms.
Conversion Factor: 1 abΩ = 10^-9 Ω
EMU of resistance (emu): The EMU (Electromagnetic Unit) of resistance is equivalent to Abohm.
Conversion Factor: 1 emu = 1 abΩ
Statohm (statΩ): The Statohm is another unit of resistance used in the CGS system, which is now mostly obsolete. One Statohm is the equivalent of approximately 8.98755 10^11 ohms.
Conversion Factor: 1 statΩ ≈ 8.9875 * 10^11 Ω*
ESU of resistance (esu): The ESU (Electrostatic Unit) of resistance is equivalent to Statohm.
Conversion Factor: 1 emu = 1 statΩ
Quantized Hall resistance (QHR): The Quantized Hall resistance is a fundamental constant of nature and is defined to be exactly 25,812.807 Ω. It is used in precision metrology and the calibration of resistance standards.
Conversion Factor: 1 QHR = 25,812.807 Ω
