# How to count the gate voltage and drain current from the forward transconductance value?

How do i get the ratio of Vgate/Idrain according to the value of the forward transconductance in the MOSFET data sheet? The units i got is 6 siemens, but i don't know how many is 6 siemens? Note that i'm a beginner.

• 6 siemens is 6 amps per volt. 3 volts gate to source means 18 amps drain current for example. – Andy aka Jun 17 at 8:46
