EMF units

Electric Fields
Usually measured in volts per metre (V/m)
Multiple used for large fields: 1 kilovolt per metre (kV/m) = 1000 volts per metre

Magnetic Fields
Usually measured in microteslas (µT)
Multiple used for large fields: 1 millitesla = 1000 microteslas
or small fields: 1 nanotesla = 0.001 microteslas
Other units sometimes used: 1 milligauss = 0.1 microteslas
1 ampere per metre = 1.25 microteslas
(this conversion for amperes per metre is only true for air and other non-magnetic materials. It changes in the pressure of magnectic materials such as iron.)

The following chart shows how to convert between the different units used for magnetic fields:
