This page converts gigohms into kilohms using the factor 1,000,000, and shows the reverse figure alongside it. Both units measure how strongly a component opposes current, which is why one number does the whole job.
Kilohms are the everyday scale of signal electronics — pull-ups, dividers and bias networks are nearly all in kΩ. One giga ohm is a billion of a ohm (1e9 ohms).
Below the calculator there is a step table for the values people look up most, and a second table putting real how strongly a component opposes current figures into kilohms so the number you get has something to be compared against.
The formula
gigohms- The amount you are converting, in gigohms
1,000,000- The exact number of kilohms in one gigohm
kilohms- The converted result
How it works, step by step
- Enter the value in gigohms.
- It is multiplied by 1,000,000, the exact factor between the two units.
- The answer is shown in kilohms, with the reverse conversion beneath it.
- Check the reference table if you want a figure of comparable size.
Worked examples
Multimeter input impedance: 0.01 GΩ in kilohms
At 0.01 GΩ (multimeter input impedance), the same quantity in kilohms is 0.01 × 1e+06 = 10,000 kΩ. One gigohm is 1e+06 kilohms, so the numbers grow as expected.
Human skin, dry: 0.0001 GΩ in kilohms
Human skin, dry comes to about 0.0001 GΩ. Multiplying by the factor: 0.0001 × 1e+06 = 100 kΩ. 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 kilohms are in one gigohm?
Exactly 1,000,000. 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 gigohms to kilohms?
kilohms = gigohms × 1,000,000. Reversed, gigohms = kilohms ÷ 1,000,000, which is the same as multiplying by 1e-06.
Which is the bigger unit, the gigohm or the kilohm?
The gigohm. One gigohm equals 1e+06 kilohms.
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 gigohm?
One giga ohm is a billion of a ohm (1e9 ohms).
What is a kilohm?
Kilohms are the everyday scale of signal electronics — pull-ups, dividers and bias networks are nearly all in kΩ.
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.
