Micromho Converters

Convert micromhos (µ℧) to microsiemens, millisiemens, siemens, mhos and other conductance units.

What this tool does

Convert micromhos (µ℧) to microsiemens, millisiemens, siemens, mhos and other conductance units. Type an amount in micromhos, choose the units, and the tool converts it to microsiemens. It offers 15 electrical conductance units and also shows the same amount in the others.

Inputs

  • Value: A number.
  • From: Choose one from 15 options, including Gigasiemens, Megasiemens, Kilosiemens, Siemens, Millisiemens, Microsiemens. Starts as Micromho.
  • To: Choose one of the same 15 units as "From". Starts as Microsiemens.

How to use

  1. Enter the amount you want to convert.
  2. Choose the unit to convert from and the unit to convert to.
  3. Read the result: the converted amount and the same amount in the other units. It appears once every required field has a valid value.

Worked examples

Micromhos and microsiemens are the same size, so the number does not change: an amount in micromhos is the same amount in microsiemens.

Sources: Micromho: exact by definition. Microsiemens: SI Brochure, 9th edition (2019, updated 2022), Table 7 (SI prefixes).

Limitations

  • Converts the unit of a conductance only. It does not work out conductance from resistance, current or voltage.
  • Abmho and statmho are historical CGS units, listed for completeness.

FAQs

Q: How many microsiemens is one micromho?
A: One micromho is exactly 1 microsiemens, because 1 mho is exactly 1 siemens.
Q: How many siemens is one micromho?
A: One micromho is 0.000001 siemens (one millionth).
Q: Where are micromhos used?
A: Older water test reports give conductivity in micromhos per centimeter. Newer ones give the same number in microsiemens per centimeter, because 1 micromho is exactly 1 microsiemens.
Q: Does this show resistance in ohms?
A: No. This page converts between conductance units. Conductance is the reciprocal of resistance, so to get ohms from micromhos divide 1 by the conductance in siemens.
