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
