GasUnits is a powerful converter of natural gas units for the iPhone/iPad. Developed by an industry professional, the app easily converts between 60 different gas volume, energy, and rate units. Users can switch between three calorific value natural gas streams for greater conversion accuracy. The coverter also estimates approximate volumes of Liquefied Natural Gas (LNG), Gas-to-Liquid (GTL) volumes and megawatts (MW) of power produced from input gas rates. The app has been downloaded over 3000 times since its launch and has become the accepted tool of choice by many natural gas and LNG professionals all over the globe. Unique features include: *Elegant and easy to use interface *Three different conversion bases (see below) to allow accurate calculations specific to particular calorific values *Volume and rate units – identified in both long and abbreviated names Conversion bases supported: Basis # 1: 1 MM Btu = 1,000 ft3 : 1,000 ft3 = 1 MMBtu : 1 boe = 5,800 ft3 Basis # 2: 1 MM Btu = 970 ft3 : 1,000 ft3 = 1.03 MMBtu : 1 boe = 5,600 ft3 Basis # 3: 1 MM Btu = 900 ft3 : 1,000 ft3 = 1.11 MMBtu : 1 boe = 5,400 ft3 Supported gas volume units include: Cubic feet, Thousand ft3, Million ft3, Billion ft3, Trillion ft3, Cubic meter, Thousand m3, Million m3, Billion m3, Trillion m3, British Thermal Unit, 1000 Btu, 100,000 Btu (Therm), Million Btu, Billion Btu, Trillion Btu, Million Therms, 1000 Joules, Million Joules, Gigajoules, Terajoules, Petajoules, Equivalent Barrels of Oil, Thousand boe Million boe, Equivalent tons of Oil, Thousand toe, Million toe, Metric tonne LNG, and Million Metric tonnes LNG.
