Narrative:
When I was given command of the aircraft; it was below class a airspace on a VFR flight plan at 15;000 MSL. The altimeter setting was set as appropriate for the airspace and altitude it was in. I decided to climb to FL190 and activate our IFR flight plan. After reaching FL190 I forgot to reset my altimeter setting to 29.92. The effect of this was that the aircraft was flying approximately 300 feet lower than indicated by my altimeter. I did not notice this until questioned about it by the center controller approximately 20 minutes after reaching FL190. I corrected my error and the aircraft resumed flight at the correct altitude.
