To convert megohms to kilohms, multiply by 1000. That factor is the whole relationship: both units measure how strongly a component opposes current, so the conversion is a proportion with no offset and no substance-specific constant.
One mega ohm is a million of a ohm (1e6 ohms). Kilohms are the everyday scale of signal electronics — pull-ups, dividers and bias networks are nearly all in kΩ.
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
megohms- The amount you are converting, in megohms
1000- The exact number of kilohms in one megohm
kilohms- The converted result
How it works, step by step
- Enter the value in megohms.
- It is multiplied by 1000, 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
Common pull-up resistor: 0.01 MΩ in kilohms
Take common pull-up resistor, roughly 0.01 MΩ. The conversion is a single multiplication — 0.01 × 1000 — giving 10 kΩ. Because the relationship is proportional, doubling the input doubles the answer to 20 kΩ.
Multimeter input impedance: 10 MΩ in kilohms
Take multimeter input impedance, roughly 10 MΩ. The conversion is a single multiplication — 10 × 1000 — giving 10,000 kΩ. Because the relationship is proportional, doubling the input doubles the answer to 20,000 kΩ.
How to read your score
Frequently asked questions
How many kilohms are in one megohm?
Exactly 1000. 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 megohms to kilohms?
kilohms = megohms × 1000. Reversed, megohms = kilohms ÷ 1000, which is the same as multiplying by 0.001.
Which is the bigger unit, the megohm or the kilohm?
The megohm. One megohm equals 1000 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 megohm?
One mega ohm is a million of a ohm (1e6 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.
