Verdict
The clearest difference is in-app purchases: mConvertIt at none against Calculator Smart's 3. mConvertIt also leads on ads (none vs shown). Calculator Smart's advantage is update cadence (every 4 months vs every 21 months) and device support (6 vs 3). On price and iOS requirement there is nothing between them.
