Electrical resistance measures a material's opposition to the flow of electric current. Formulated by Georg Simon Ohm, Ohm's Law states that Resistance (R) = Voltage (V) / Current (I). One ohm is defined as the resistance between two points of a conductor when a constant potential difference of 1 volt produces a current of 1 ampere.
Electronics applications cover an immense spectrum of resistance values: 1 Gigaohm (GΩ) = 1,000 Megaohms (MΩ) = 1,000,000 Kiloohms (kΩ) = 1,000,000,000 Ohms (Ω). Low-resistance conductors (cables, shunt resistors) use milliohms (mΩ), circuit board biasing resistors use kiloohms (kΩ), and electrical insulators use megaohms and gigaohms.
Through-hole resistors are commonly rated in kiloohms (such as 1kΩ, 4.7kΩ, 10kΩ, and 100kΩ). Converting accurately between standard ohms and kiloohms is vital when reading electronic schematics and designing microcontroller circuits.
There are exactly 1,000 ohms in 1 kiloohm (1 kΩ = 1,000 Ω). To convert kiloohms to ohms, multiply by 1,000.
There are exactly 1,000,000 ohms (or 1,000 kiloohms) in 1 megaohm.
To convert ohms (Ω) to kiloohms (kΩ), divide the ohm value by 1,000. For instance, 4,700 Ω ÷ 1,000 = 4.7 kΩ.
According to Ohm's Law, Resistance = Voltage / Current (R = V / I), where R is in ohms, V is in volts, and I is in amperes.
