Human Factors; Procedure
During training flights at a local practice area; I briefly confused metric and imperial measurements and exceeded the altitude limit of 400 ft AGL. The software on my remote controller presents all measurements in metric and I briefly inadvertently mistook it for imperial (feet) thinking I was only at 196.1 FEET; when in fact it was 196.1 METERS / 643 FEET due to the conversion. I had updated my software and firmware just before my flight earlier that day and neglected to double check the maximum altitude setting which had been reset during the update. System was not configured properly by PIC in preflight to allow for an automated alert. I'd like to note; during my flight; I did not see any other aircraft in the air nearby; it was a very clear day and I hope my actions did not cause any further incident. I take full responsibility for my error and will take all proper measures in the future to ensure this never happens again. I have taken extensive time to review all my training materials and the Part 107 certification guide to ensure all rules and regulations are well understood and comprehended.
