Convert ohms to kilohms and kilohms to ohms instantly. Bidirectional resistance converter with formula and common values.
To convert ohms to kilohms, divide by 1,000 (or multiply by 0.001). The kilohm is widely used in electronics for expressing resistor values in a compact format.
| Ohms (Ω) | Kilohms (kΩ) |
|---|---|
| 100 | 0.1 |
| 220 | 0.22 |
| 470 | 0.47 |
| 1,000 | 1 |
| 4,700 | 4.7 |
| 10,000 | 10 |
| 47,000 | 47 |

One ohm equals 0.001 kilohms. Divide the ohm value by 1,000 to get kilohms.
The ohm (symbol: Ω) measures electrical resistance. It is defined as the resistance that produces a potential difference of one volt when a current of one ampere flows through it.
Kilohms are convenient for resistor values above 1,000 Ω. For example, a 4,700 Ω resistor is more easily written as 4.7 kΩ.
Resistors use color bands or printed codes. A 4.7 kΩ resistor might show "472" (47 × 10²) or color bands yellow-violet-red.
