One kilohm is exactly 1e-06 gigohms, so converting kilohms to gigohms is a single multiplication. Enter any figure and the result appears as you type — the arithmetic runs in your browser, so nothing is sent anywhere.
One giga ohm is a billion of a ohm (1e9 ohms). Kilohms are the everyday scale of signal electronics — pull-ups, dividers and bias networks are nearly all in kΩ.
Two tables follow: rounded steps for quick lookup, and a set of real reference quantities converted into gigohms, which is usually more useful than the bare number.
The formula
kilohms- The amount you are converting, in kilohms
1e-06- The exact number of gigohms in one kilohm
gigohms- The converted result
How it works, step by step
- Enter the value in kilohms.
- It is multiplied by 1e-06, the exact factor between the two units.
- The answer is shown in gigohms, with the reverse conversion beneath it.
- Check the reference table if you want a figure of comparable size.
Worked examples
Human skin, dry: 100 kΩ in gigohms
Human skin, dry comes to about 100 kΩ. Multiplying by the factor: 100 × 1e-06 = 0.0001 GΩ. Dividing the answer back by 1e-06 returns the figure you started with, which is the quickest way to check you have the factor the right way up.
Heating element, 2 kW at 230 V: 0.0264 kΩ in gigohms
Heating element, 2 kW at 230 V comes to about 0.0264 kΩ. Multiplying by the factor: 0.0264 × 1e-06 = 2.64e-08 GΩ. Dividing the answer back by 1e-06 returns the figure you started with, which is the quickest way to check you have the factor the right way up.

Frequently asked questions
How many gigohms are in one kilohm?
Exactly 1e-06. Every figure on this page is that one number multiplied by your input, so the only rounding is at the display step.
What is the formula to convert kilohms to gigohms?
gigohms = kilohms × 1e-06. Reversed, kilohms = gigohms ÷ 1e-06, which is the same as multiplying by 1,000,000.
Which is the bigger unit, the kilohm or the gigohm?
The gigohm. One kilohm is only 1e-06 of a gigohm, so it takes 1e+06 kilohms to make one gigohm.
What does this quantity actually measure?
Both units measure how strongly a component opposes current. That is why a single factor is enough: there is no temperature offset and no material property involved, unlike conversions that cross between different quantities.
What is a kilohm?
Kilohms are the everyday scale of signal electronics — pull-ups, dividers and bias networks are nearly all in kΩ.
What is a gigohm?
One giga ohm is a billion of a ohm (1e9 ohms).
Why does my answer differ from another converter?
Almost always because the other tool rounded the factor before multiplying. This page keeps full double precision through the calculation and rounds only for display, and it prints the factor it used so you can see where any difference came from.
