One microhm is exactly 1e-06 ohms, so converting microhms to ohms 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.
The ohm is the SI unit of electrical resistance: one volt of drop per ampere of current. One micro ohm is one millionth of a ohm (1e-6 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 ohms so the number you get has something to be compared against.
The formula
microhms- The amount you are converting, in microhms
1e-06- The exact number of ohms in one microhm
ohms- The converted result
How it works, step by step
- Enter the value in microhms.
- It is multiplied by 1e-06, the exact factor between the two units.
- The answer is shown in ohms, with the reverse conversion beneath it.
- Check the reference table if you want a figure of comparable size.
Worked examples
A round figure: 1 µΩ in ohms
A round figure comes to about 1 µΩ. Multiplying by the factor: 1 × 1e-06 = 1e-06 Ω. 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.
A larger figure: 100 µΩ in ohms
At 100 µΩ (a larger figure), the same quantity in ohms is 100 × 1e-06 = 0.0001 Ω. One microhm is 1e-06 ohms, so the numbers shrink as expected.
How to read your score
Frequently asked questions
How many ohms are in one microhm?
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 microhms to ohms?
ohms = microhms × 1e-06. Reversed, microhms = ohms ÷ 1e-06, which is the same as multiplying by 1,000,000.
Which is the bigger unit, the microhm or the ohm?
The ohm. One microhm is only 1e-06 of a ohm, so it takes 1e+06 microhms to make one ohm.
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 microhm?
One micro ohm is one millionth of a ohm (1e-6 ohms).
What is a ohm?
The ohm is the SI unit of electrical resistance: one volt of drop per ampere of current.
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.
