A kilohm is:

In the metric system, the prefix 'kilo-' always means 1,000. When applied to the unit of electrical resistance (ohms), a 'kilohm' represents 1,000 ohms. Options suggesting 0.1, 0.001, or 10 ohms represent incorrect prefixes (such as deci, milli, or deca). Remembering that 'kilo' universally multiplies the base unit by a thousand will help you confidently convert units like volts, watts, and ohms. You will frequently see resistors labelled in kilohms (abbreviated as k or kΩ) in amateur radio circuits.
