UnitConv app helps in quick unit conversion from SI units to USCS/Imperial and vice verse for most of the units associated in engineering conventions and computations. Therefore, App can be very handy for engineers and students dealing with subjects such as thermodynamics, fluid mechanics, heat transfers and other applied engineering subjects where property data requires frequent conversion. This app covers units under following18 major categories. 1. Mass (kg, lbm, slug, ounce, grain, M. Tonne, Ton) 2. Length (meter, ft, cm, in, mm, km, mile) 3. Area (m^2, ft^2, cm^2, in^2) 4. Volume (liter, gal (US), gal (UK), m^3. ft^3, fl_oz) 5. Temperature (deg C, deg F, Kelvin, Rankin) 6. Flow rate (lpm, gpm, cc/sec, ci/sec) 7. Force (Newton, dyne, kgf, lbf) 8. Pressure (kPa, Bar, psi, atm, kgf/cm^2, in_wg, mm_Hg ) 9. Velocity (m/sec. ft/sc, kmh, mph) 10. Energy (Joule, cal, BTU, m.kgf, ft.lbf) 11. Power (kW, hp, kcal/s, BTU/hr, kgf.m/s, lbf.ft/s) 12. Density (kg/m^3, lb/ft^3, m/cc, lbf.sec^2/in^4) 13. Dynamic Viscosity (Pa.sec, poise, cP, reyn, kgf.sec/m^2, lbf.sec/ft^2) 14. Kinematic viscosity (stokes, cSt, newts) 15. Specific heat (joule/kg.K, BTU/lb.F, cal/kg.C) 16. Thermal Conductivity (W/m.K, BTU/hr.ft.F) 17. Enthalpy (kJ/kg, BTU/lb) 18. Entropy (kJ/kg.K, BTU/hr.R) By default, the app provides the conversion factor for units listed above. However, users can enter in any data and then convert its value in the chosen unit from the picker. In addition app generates a conversion table for the chosen unit. The following screen shots illustrate this for pressure as an example. There is a separate section under Flow Rate category for gas flow rate conversion. One can quickly convert gas flow rate in Slpm to Scfm and vice verse as shown in the screen shot. With Best Compliments From: Kaup Shenoy Associates.

Verdict
The clearest difference is update cadence: Bulk at every 2 days against SI To USCS unit Conversion's every 10 months. SI To USCS unit Conversion's advantage is iOS requirement (14.3 vs 18.0). On price, ads, in-app purchases and device support there is nothing between them.
