Verdict
The clearest difference is in-app purchases: Unit Converter Elite at none against Unit Converter Engineering Pro's 2. Unit Converter Elite also leads on iOS requirement (11.0 vs 13.0). Unit Converter Engineering Pro's advantage is ads (none vs shown) and update cadence (weekly vs every 53 months). On price and device support there is nothing between them.
