Unity vs Well Testing Suite

The best unit converter is now even better! Precise, powerful & customisable. Unity is a unit converter that is like no other - because it's built with simplicity in mind. Unity is also powerful - with over 500 conversion types to choose from already, and more arriving with every update. Unity can reliably convert units in 18 categories including Angles, Area, Capacitance, Clothing, Currency/Crypto, Data, Data Rates, Distance, Energy, Mileage, Power, Pressure, Speed, Temperature, Time, Typography, Volume and Weight. You can also save your regular conversions as favourites by tapping the icon on the conversion view and then see them right on the home screen for easy access. Well, there's more important things to do with your day than search for pennyweights and millifarads. Currency rates are updated from our reliable servers. Rates are downloaded on startup and can be refreshed at any time from the conversion view. Up to date currency graphs show how rates have changed over the past day, week, month, or year. Using your location, Unity also creates a suggested conversions to your home currency right from the home screen. Or build your own conversions for countries you're visiting on your next trip! You can set the number of decimal points you would like conversions to be calculated too, work in negative numbers and use the built in calculator for more complex conversions for the highest precision. As well as the huge range of units already built in, we are happy to add any unit to the app to keep our loyal users happy - just get in touch!

H2Oil Well Testing Suite is a comprehensive engineering calculator app designed for well test supervisors, field engineers, and operations teams working in oil and gas. Every calculation runs entirely on your device - no internet connection, no cloud, no subscriptions. Your data never leaves your phone. CALCULATORS INCLUDED Well Testing - AGA-3 Orifice Gas Metering (Reader-Harris/Gallagher, ISO 5167-2 / API MPMS 14.3.1) - Dual Choke Sizing (Thornhill-Craver / Economides, critical and subcritical) - Choke Flow Rates (gas, oil, multiphase) - Separator Retention Time (two and three-phase) - Bottoms Up Time / kill sheet calculations - Solution GOR (Standing 1947) - Oil and Gas Rate (surface and reservoir) - MCF and Shrinkage Flow Assurance - Well Test Simulator: full flow path from Wellhead to SSV, Choke, Heater, Separator, Flare, Surge Tank and Atmospheric Tank. Live pressure, temperature and velocity at every node. API RP 14E erosional velocity and hydrate risk at each segment.
