EC, µS, mS –– How to convert?

Modified on Tue, Aug 30, 2022 at 6:29 AM

1 mS (millisiemens) = 1,000 µS (microsiemens) = 1 EC


For example:


1500 µS = 1.50 mS = 1.50 EC


2.85 mS = 2.85 EC = 2,850 µS


5.90 mS = 5.90 EC = 5,900 µS


On most Apera testers, µS will be automatically switched to mS at the point it reaches 2,000 µS.
