I believe you observed the voltage across some resister.Divide the rms voltage with the value of resistance to get current flowing through it.For more understanding, is there a knob named current/division on CRO?

Measure the voltage waveform across a resistance in series and use ohm's law to convert the units displayed from voltage to current.

Easy.
