A kilohm (kΩ) is a unit of electrical resistance equal to 1,000 ohms. The metric prefix "kilo" denotes a factor of one thousand. Kilohms are commonly used to express medium to high resistance values found in electronic circuits, particularly in analog electronics, signal processing, and digital logic circuits. This unit makes it easier to read and communicate resistance values without dealing with large numbers.
The ohm (Ω) is the base SI unit of electrical resistance, named after German physicist Georg Simon Ohm who formulated Ohm's Law. One ohm represents the resistance when a potential difference of one volt produces a current of one ampere. Ohms are used universally in electrical engineering to specify the resistance of conductors, resistors, and other circuit elements. Understanding ohms is fundamental to designing and analyzing any electrical or electronic system.
Converting kilohms to ohms is simple:
Example: 4.7 kΩ × 1,000 = 4,700 Ω
To convert kilohms to ohms, multiply the kilohm value by 1,000. For example, 5 kΩ × 1,000 = 5,000 Ω. This is because "kilo" is a metric prefix meaning one thousand, so one kilohm equals exactly one thousand ohms.
10 kilohms equals 10,000 ohms. This is calculated by multiplying 10 by 1,000. A 10 kΩ resistor is one of the most common resistor values used in electronics, particularly for pull-up resistors in digital circuits and general-purpose applications.
Kilohms provide a more convenient way to express larger resistance values. Writing "4.7 kΩ" is clearer and more compact than "4,700 Ω". In electronics, most resistors range from hundreds of ohms to millions of ohms, making kilohms and megohms practical for everyday use. This notation also reduces the chance of decimal point errors.
Yes, 1 kΩ is exactly the same as 1,000 Ω. These are just two different ways of expressing the same resistance value. In circuit diagrams and component specifications, you might see either notation depending on the context and regional preferences.
Standard kilohm resistor values include 1.0, 1.2, 1.5, 1.8, 2.2, 2.7, 3.3, 3.9, 4.7, 5.6, 6.8, 8.2, 10, 12, 15, 18, 22, 27, 33, 39, 47, 56, 68, 82, and 100 kΩ. These follow the E12 or E24 standard series, which provides a geometric progression of values for resistor manufacturing.
Resistors use color codes or numerical markings. For a 4.7 kΩ resistor, the color bands would be yellow-violet-red (or yellow-violet-black-brown for 5-band). Surface mount resistors might be marked "472" (47 × 10² = 4,700 Ω = 4.7 kΩ). Always verify with a multimeter for precision.
