SI To USCS unit Conversion2.3 - App Store

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.

Version History Updated for iOS 18 devices. 2.3 05/02/2025 Updated for iOS17 (iPhone15..) devices. 2.2 04/28/2024 Mandatory update for iOS 16. 2.1 05/12/2023 Updated iOS 14.4 and app documentation with additional link provided for validation of reference apps. 2.0 03/04/2021 Updated for iOS 14 devices. 1.9 10/29/2020 Updated with iOS 13.0 and macOS Catalina. 1.8 08/07/2020 Mandatory update for iOS12. 1.7 05/22/2019 Updated using latest Xcode and iOS 11. 1.6 01/22/2019 iOS 8 compliant. Updated for iPhone 6 and iPhone 6+ with bug fixes. Runs on Apple iOS devices with iOS 6.1 and above. 1.5 05/01/2015 This update is mainly for 4 inch display (iPhone5) where a few unconstrained UI objects got displaced in 4-in screen layout as they were originally placed for 320x480px devices. 1.4 09/16/2013 Increased the significant digits for the unit conversion table. Now the conversion table displays up to four decimal places for better accuracy and minimizes round off error. Also updated for iPhone 5 compliance. 1.3 07/09/2013 This version has additional feature on conversion table. Accordingly app displays the conversion table under selected engineering unit category for a specific unit on a separate screen as shown in the screen shot for 'psi' unit conversion as an example. 1.2 04/07/2013 Added 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 versa as shown in the screen shot. V1.1 06/06/2012 1.0 02/20/2012
